Complete Question
Question: In the bronze medal game of the 2014 FIBA Asia Cup... In the bronze medal game of the 2014 FIBA Asia Cup, and with his team down by two points, Philippines guard Paul Dalistan was fouled while attempting a three-pointer at the buzzer. He missed the shot and headed to the line for three foul shots.
1. Watch the video of Dalistan preparing to take his first shot. Before he shoots, what is the probability that Philippines will win the game? Lose the game? Send it into overtime? Dalistan’s free throw percentage is 84.6%
Answer:
a
The probability that Philippines will win the game is [tex]P(A) = 0.6055 [/tex]
b
The probability that Philippines will lose the game is [tex]P(B) = 0.00365[/tex]
c
The probability that the game will be sent to overtime is [tex]P(C) = 0.06 [/tex]
Step-by-step explanation:
From the question we are told that
The probability of Paul Dalistan making a shot is p = 0.846
The probability of Paul Dalistan not making the shot is [tex]q = 1- p = 1- 0.846=0.154[/tex]
Paul Dalistan team was down by two points
This mean that for Paul Dalistan's team to win the game he must make the 3 free throws
So the probability that Philippines will win the game is mathematically represented as
[tex]P(A) = p^3 [/tex]
=> [tex]P(A) = 0.846^3[/tex]
=> [tex]P(A) = 0.6055 [/tex]
Gnerally for Paul Dalistan's team to loss the game it means that Paul Dalistan did not make any of the free shot
Hence the probability that Philippines will loss the game is
[tex]P(B) = q^3[/tex]
=> [tex]P(B) = (0.154 )^3[/tex]
=> [tex]P(B) = 0.00365[/tex]
Generally for the game to be sent to overtime then the game must be tied and for the game to be tied, Paul Dalistan have to make 2 out of the three shots
Hence the probability that game will go to overtime is
[tex]P(C) = 3 * 0.846 * 0.154 * 0.154[/tex]
[tex]P(C) = 0.06 [/tex]
What is the equation olf the line that is parallel to the gven line and has an x-intercept of 3? Oy-x+3 Oy-x+2 Oy=-x+3 Oy=-x+2
Answer:
It’s D
Step-by-step explanation:
The equation of the parallel line is y = x - 3, the correct option is C.
What is y-intercept of a function?The intersection of the graph of the function with the y-axis gives y-intercept of that function. The y-intercept is the value of y on the y-axis at which the considered function intersects it.
Assume that we've got: y = f(x)
At y-axis, we've got x = 0, so putting it will give us the y-intercept.
Thus, y-intercept of y = f(x) is y = f(0)
We are given that;
x-intercept = 3
Now,
we can find the equation of the line parallel to the given line and passing through the point (3, 0):
The given line has an equation of y = x + 3. This is already in slope-intercept form, so we can see that the slope is 1. The parallel line will have the same slope of 1.
The point that the parallel line passes through is (3, 0). We can use this point and the slope to write the equation of the parallel line in point-slope form:
y - 0 = 1(x - 3)
y = x - 3
Therefore, the slope intercept will be y=x-3

Jessie read three books in one week. At this rate, how many books will she read in 3 weeks?
Answer:
Jessie will read 9 books in 3 weeks.
Step-by-step explanation:
3 x 3 = 9
Answer: 9
Step-by-step explanation: If you need an equation, you can create one:
t = total number of books read
w = weeks
t = 3w
The 3 is there because she reads 3 books weekly, so you multiply the number of weeks by the number of books she reads.
Plug in 3 weeks:
t = 3(3)
t = 9 books
Jessie reads 9 books in 3 weeks.

Step-by-step explanation:
Researchers have noted a decline in cognitive functioning as people age (Bartus, 1990). However, the results from other research suggest that the antioxidants in foods such as blueberries can reduce and even reverse these age-related declines, at least in laboratory rats (Joseph et al., 1999). Based on these results, one might theorize that the same antioxidants might also benefit elderly humans. Suppose a researcher is interested in testing this theory. The researcher obtains a sample of adults who are older than 65, and gives each participant a daily dose of a blueberry supplement that is very high in antioxidants. After taking the supplement for 6 months, the participants are given a standardized cognitive skills test and produce a mean score of . For the general population of elderly adults, scores on the test average μ and form a normal distribution with σ=9.
(a)-Can the researcher conclude that the supplement has a significant effect on cognitive skill? Use a two-tailed
Complete Question
The complete question is shown on the first uploaded image
Answer:
a
Yes the researcher can conclude that the supplement has a significant effect on cognitive skill
b
[tex]d = 0.5778 [/tex]
c
The result of this hypothesis test shows that there is sufficient evidence to that the supplement had significant effect.The measure of effect size is large due to the large value of Cohen's d (0.5778 > 0.30 )
Step-by-step explanation:
From the question we are told that
The sample size is n=16
The sample mean is [tex]M = 50.2[/tex]
The standard deviation is [tex]\sigma = 9[/tex]
The population mean is [tex]\mu = 45[/tex]
The level of significance is [tex]\alpha = 0.05[/tex]
The null hypothesis is [tex]H_o \mu =45[/tex]
The alternative hypothesis is [tex]H_a \mu \ne 45[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{M - \mu}{\frac{\sigma}{\sqrt{n} } }[/tex]
=> [tex]z = \frac{50.2 - 45}{\frac{9}{\sqrt{16} } }[/tex]
=> [tex]z = 2.31 [/tex]
Generally the p-value is mathematically represented as
[tex]p-value = 2 * P(Z > z )[/tex]
[tex]p-value = 2 * P(Z > 2.31 )[/tex]
From the z-table
[tex]P(Z > 2.31 ) = 0.010444[/tex]
=> [tex]p-value = 2 * 0.010444 [/tex]
=> [tex]p-value = 0.021 [/tex]
From the obtained values we see that [tex]p-value < 0.05[/tex]
Decision Rule
Reject the null hypothesis
Conclusion
There is sufficient evidence to conclude that the supplement has a significant effect on the cognitive skill of elderly adults
Generally the Cohen's d for this study is mathematically represented as
[tex]d = \frac{M - \mu}{\sigma }[/tex]
=> [tex]d = \frac{50.2 -45}{9 }[/tex]
=> [tex]d = 0.5778 [/tex]

Sabendo que as retas r, s e t são paralelas, determine o valor de x na imagem a seguir
a)3
b)3,2
c)3,5
d)4
Answer:
x = 3.2
Step-by-step explanation:
Aquí, queremos encontrar el valor de x en la imagen de arriba.
Matemáticamente eso sería;
x / 4 = (x + 16) / (20 + 4)
x / 4 = (x + 16) / 24
Cruz multiplicar 24 * x = 4 (x + 16)
24x = 4x + 64
24x - 4x = 64
20x = 64
x = 64/20 x = 3,2
From the transversal proportionality theorem of parallel lines r,s,t. the value of x is 3.2.
It is given that r, s, t are parallel to each other. The length of the sides is given as 16, 20, 4, x. we need to find the value of x.
What is the transversal proportionality theorem?If two or more parallel lines are cut by two transversals, then they divide the transversals proportionally.
From the transversal proportionality theorem,
When r, s, t are parallel to each other then a / x = b / y
so,
[tex]\rm \frac{16}{x} = \frac{20}{4} \\\rm x = \frac{16}{5} \\\rm x = 3.2[/tex]
Therefore, from the transversal proportionality theorem of parallel lines r,s,t. the value of x is 3.2.

m/4 - 3 = 6 + m/2
Answer:
m = -36
Step-by-step explanation:
Solve for m:
m/4 - 3 = m/2 + 6
Hint: | Put the fractions in m/4 - 3 over a common denominator.
Put each term in m/4 - 3 over the common denominator 4: m/4 - 3 = m/4 - 12/4:
m/4 - 12/4 = m/2 + 6
Hint: | Combine m/4 - 12/4 into a single fraction.
m/4 - 12/4 = (m - 12)/4:
(m - 12)/4 = m/2 + 6
Hint: | Put the fractions in m/2 + 6 over a common denominator.
Put each term in m/2 + 6 over the common denominator 2: m/2 + 6 = m/2 + 12/2:
(m - 12)/4 = m/2 + 12/2
Hint: | Combine m/2 + 12/2 into a single fraction.
m/2 + 12/2 = (m + 12)/2:
(m - 12)/4 = (m + 12)/2
Hint: | Make (m - 12)/4 = (m + 12)/2 simpler by multiplying both sides by a constant.
Multiply both sides by 4:
(4 (m - 12))/4 = (4 (m + 12))/2
Hint: | Cancel common terms in the numerator and denominator of (4 (m - 12))/4.
(4 (m - 12))/4 = 4/4×(m - 12) = m - 12:
m - 12 = (4 (m + 12))/2
Hint: | In (4 (m + 12))/2, divide 4 in the numerator by 2 in the denominator.
4/2 = (2×2)/2 = 2:
m - 12 = 2 (m + 12)
Hint: | Write the linear polynomial on the left hand side in standard form.
Expand out terms of the right hand side:
m - 12 = 2 m + 24
Hint: | Move terms with m to the left hand side.
Subtract 2 m from both sides:
(m - 2 m) - 12 = (2 m - 2 m) + 24
Hint: | Combine like terms in m - 2 m.
m - 2 m = -m:
-m - 12 = (2 m - 2 m) + 24
Hint: | Look for the difference of two identical terms.
2 m - 2 m = 0:
-m - 12 = 24
Hint: | Isolate terms with m to the left hand side.
Add 12 to both sides:
(12 - 12) - m = 12 + 24
Hint: | Look for the difference of two identical terms.
12 - 12 = 0:
-m = 24 + 12
Hint: | Evaluate 24 + 12.
24 + 12 = 36:
-m = 36
Hint: | Multiply both sides by a constant to simplify the equation.
Multiply both sides of -m = 36 by -1:
(-m)/(-1) = -36
Hint: | Any nonzero number divided by itself is one.
(-1)/(-1) = 1:
Answer: m = -36

Answer:
(f - g)(x) = -x² + 3x + 7 ⇒ D
Step-by-step explanation:
In the expression x - a, you will subtract a from x
Let us solve the question using this fact
∵ f(x) = 3x + 1
∵ g(x) = x² - 6
→ We need to find (f - g)(x), which means subtract g from x
∵ (f - g)(x) = (3x + 1) - (x² - 6)
→ The negative sign before (x² - 6) will change their signs
∵ - (x² - 6) = -(x²) + -(-6)
→ Remember (-)(+) = - and (-)(-) = (+)
∴ - (x² - 6) = -x² + 6
→ Substitute it in (f - g)(x)
∴ (f - g)(x) = 3x + 1 - x² + 6
→ Add the like terms
∴ (f - g)(x) = 3x - x² + (1 + 6)
∴ (f - g)(x) = 3x - x² + 7
→ Re-arrange the terms from the greatest power of x
∴ (f - g)(x) = -x² + 3x + 7
