For Fredrico to make an average of at least 7.4 on all four dives, he must get at least 5.6 in his last dive.

The average is the mean of the total scores that Fredrico scored in his dives.

The average can be computed by dividing the total scores by the number of dives.

The average is the quotient of the division operation of the total scores and the number of dives.

The total score based on an average of 7.4 = 29.6

The total scores obtained = 24 (7.2 + 8.4 + 8.4)

The remaining score to obtain to get the average of 7.4 = 5.6 (29.6 - 24)

Thus, Fredrico needs an additional 5.6 score in the last dive to make the average.

Fredrico needs to score at least 5.6 on his final dive in order to achieve an average of at least 7.4 on all four dives.

Let's assume the required score would be x on his final dive

Mean = ∑x/n

The average represents the mean of all of Fredrico's dive-related scores.

Here, n = 4

Sum of Observations (∑x) = 7.2 + 8.4 + 8.4 + x

∑x  = x + 24

Mean = ∑x/n

Substitute the values in the above formula,

⇒ 7.4 = (x + 24) / 4

Apply the cross-multiplication operation in the above equation,

⇒ 7.4 × 4= (x + 24)

⇒ 29.6 = x + 24

⇒ x = 29.6 - 24

Apply the subtraction operation to get

⇒ x = 5.4

Therefore, Fredrico needs to score at least 5.6 on his final dive

The angle subtend an arc length of 7 feet is 44.56°

Given,

Radius of a circle = 9 feet

Arc length of a circle = 7 feet

Arc length :

The distance between two places along a segment of a curve is known as the arc length.

Formula for arc length:

AL = 2πr (C/360)

Where,

r is the radius of the circle

C is the central angle in degrees

Now,

AL = 2πr (C/360)

7 = 2 × π × 9 (C/360)

7 = 18 π (C/360)

7/18π = C/360

C = (7 × 360) / (18 × π)

C = (7 × 20) / π

C = 140 / π

C = 44.56°

That is,

The angle subtend an arc length of 7 feet is 44.56°

We are given a dot plot as shown which indicates the ages of members of an intermediate swim class.

The dot plot indicates a cluster to the right for the values;

This indicates that a reasonable amount of the members are within that age range.

For this reason, it is not likely that Mira will be able to convince her mother.

This is because Mira's age (13 years old) is within the area where the data are clustered.

Therefore;

ANSWER:

(1) The data are clustered between 11 and 14 years old

(2) It is not likely that she will be able to convince her mother

(3) Mira's age is within the area where the data are clustered.

We proceed to use the quadratic formula, we have:

Answer:

Explanation:

Here, we want to find the value of m and n

If we substituted a supposed root into the parent polynomial, the value after evaluation is the remainder. If the remainder is zero, then the value substituted is a root.

for x+ 3

x + 3 = 0

x = -3

Substitute this into the first equation as follows:

We do this for the second value as follows:

x-2 = 0

x = 2

Substitute this value into the polynomial:

Now, we have two equations so solve simultaneously:

Add both equations:

To get the value of n, we simply susbstitute the value of m into any of the two equations. Let us use the second one:

The first step to solving this problem is to put the variable on one side. Thus, you must move 7 to the right side to make   [tex]\frac{f}{25} \leq -3[/tex]

Next, you must multiply the 25 to the right side to isolate the variable

You get [tex]f \leq -75[/tex]

With this explained, the answer would be the second option (f=-75)

Hope this helped :)

1.volume = mass*density

v = 1.2 * 3.6 = 4.32 cm3

The density of a substance quantifies how tightly its molecules are packed, which affects how heavy or light it is.

Density is calculated as follows: density=mass/volume. Most often, mass is measured in grams or kilograms. Most often, volume is measured in cubic centimeters (cm3), cubic meters (m3), or millileters (mL).

How can you find mass from density?

multiply the volume by the density.

Mass per unit volume is the definition of density.

ρ = m V

This can be rearranged to yield the mass expression.

m = ρ × V

Example:

What mass of the liquid is present if 500 mL of it has a density of 1.11 g/mL

m = ρ × V = 500 mL × 1.11 g

1 mL = 555 g

The expression of the mathematical statement given as the difference of 4R and 108 is |4R - 108|

From the question, the mathematical statement is given as

The difference of 4R and 108

In mathematics, the difference of numbers or expressions implies that we subtract one of the numbers from the other number or expression

This in other words means that difference means subtraction

So, we have the following representation

The difference of 4R and 108 ⇒ 4R - 108

However, we do  not know the bigger number.

So, the expression can be rewritten as

The difference of 4R and 108 ⇒ 108 - 4R

So, we have two options

4R - 108 and 108 - 4R

When both expressions are combined, we introduce the absolute value symbol i.e. |.....|

|4R - 108|

Hence, the expression represented by the statement is |4R - 108|

The composition of functions g(x) and f(x) evaluated in x = 5 is:

(g o f)(5) = 6

Here we have two functions f(x) and g(x), and we want to find the composition evaluated in x = 5, this is:

(g o f)(5) = g( f(5) )

So first we need to evaluate f(x) in x = 5, and then g(x) in f(5).

f(5) = 5² - 6*5 + 2 = 25 - 30 + 2 = -3

Then we have:

(g o f)(5) = g( f(5) ) = g(-3)

Evaluating g(x) in x = -3 gives:

We have the following inequality

We must graph this inequality, In order to understand this I will explain term by term

But first, we must remember that in mathematics, the absolute value or modulus of a real number x, denoted by |x|, is the non-negative value of x regardless of the sign, positive or negative. This must be taken into account for the |x+3| term.

That is to say that the value will always be assumed by its magnitude and we will tend to have the same behavior on both the negative and positive x-axis.

Taking this into account and that the slope is -2/3 the graph would look like this:

Now, we must remember two rules of function translation, these are as follows:

y = f(x) original funtion

y = f(x+c) it is moved horizontally "c" units to the left

y = f(x)+c it moves vertically "c" units upwards

So taking into account these rules our graph is shifted 3 units to the left and 4 units upwards.

In conclusion, this graph looks like this:

All of the base of the slice corresponds to the circumference of the circle, but since half of it just accounts for the base of the parllelogram therefore, the base is approximately equal to only half of the circumference.
