Answer:
x = -8
Step-by-step explanation:
using what's given, you can make the following equation:
3 + 2x + 22 = x + 17
3 + 22 + 2x - x = 17
25 + x = 17
x = 17 - 25
x = -8
Answer:
Step-by-step explanation:
3 + 2x + 22= x + 17
2x + 25 = x + 17
x + 25 = 17
x = -8
3 + 2(-8) + 22 = -8 + 17
25 - 16 = 9

Given f(x) = -x + 7, evaluate f(-2).
Answers
Answer:
f(x)=9
Step-by-step explanation:
f(x)=-(-2)+7
f(x)=9
2 +7
when f is -2 and x in the equation is negative the -2 would be positive because 2 negative equals a positive so 2+7 = 9
f(-2)= 2+7= 9

If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled fewer than 194 feet
Answers
Complete Question
Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 220 feet and a standard deviation of 40 feet. Let X = distance in feet for a fly ball.
If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled fewer than 194 feet
Answer:
The value is [tex]P(X < 194 ) = 0.25785[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 220 \ feet[/tex]
The standard deviation is [tex]\sigma = 40 \ feet[/tex]
Generally the probability that this ball traveled fewer than 194 feet is mathematically represented as
[tex]P(X < 194 ) = P(\frac{X -\mu}{\sigma } < \frac{194 - 220}{40} )[/tex]
Generally [tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
[tex]P(X < 194 ) = P(Z < -0.65 )[/tex]
From the z-table the probability of [tex](Z < -0.65 )[/tex]
[tex]P(Z < -0.65 ) = 0.25785[/tex]
So
[tex]P(X < 194 ) = 0.25785[/tex]

Answer:
13) 28
14) 22
15) 24
16)13
Step-by-step explanation:
13) Because they all lie on the same line, AC would be AB+BC, or 16+12, or 28.
14) Same thing as 13, 13+9=22
15) Same thing as others but make an equation
-1+2x+11=3x+3
Simplifying the equation, we get x=7. Now, we plug in x=7 to 3x+3 to get AC.
3(7)+3=21+3=24
16) build the equation:
x+14+x+10=22
2x+24=22
2x=-2
x=-1
Now plug in x=-1 to x+14.
-1+14=13
Find the value(s) of "k" that will cause the equation 4x^2 +kx + 4 to have one real solution.
Answers
Answer: k = {8, -8}
Step-by-step explanation:
In order for a quadratic equation to have exactly one solution, the discriminant must equal zero. → b² - 4ac = 0
4x² + kx + 4 = 0
↓ ↓ ↓
a=4 b=k c=4
b² - 4ac = 0
k² - 4(4)(4) = 0
k² = 64
k = √64
k = ± 8

Keep the triangle that you created in Question 1. You will now copy the triangle to a different location on the grid using two of its angles and the included side:
In a different place on the grid, draw a new line segment of the same length as the line segment recorded in Question 1. (This will be easier if you draw the new line segment parallel or perpendicular to the corresponding line segment from Question 1.)
At each endpoint of the new line segment, create an angle of a given size. Size the angles using the angle measurements you recorded in Question 1.
Once you’ve created the angles, draw a ray through each endpoint at the specified angle measurement.
Place a point at the intersection of the two rays.
Finish copying the triangle by drawing a polygon through the three points you created.
Answers
Answer:
The triangles appear to be the same size and shape.
Step-by-step explanation:
The new triangle formed is congruent to the former one.
From question 1 the data has been revised. Which form a triangle.
Here same triangle to be determine.
Similar triangles, are those triangles which have similar properties, i.e. angles and proportionality of sides.
Here,
We have triangle from question 1 solution. While copying triangle we used to draw three sides over the measure of angles and size of the sides to get copy of triangle. The triangle obtained will be congruent to the former triangle.
Thus, the new triangle formed is congruent to the former one.

Answers
Answer:
A
Step-by-step explanation:
It’s the answer I did the math
The unit rate for the ratio is 3 laps per miles.
Given that the ratio is 78 laps/26 miles.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Now,
Unit rate =78 laps/26 miles
Divide both the numerator and the denominator by 26.
So, 78 laps÷26 miles/26 miles÷26 miles
= 3 laps/miles
Therefore, the unit rate for the ratio is 3 laps per miles.
