The two way table shows the results of a survey that asked high school students whether they have a job.
Answers
(b) 17%
Explanation:
(a)
No. of seniors = 54 + 46 = 100
Total No. = 66 + 34 + 54 + 46 = 200
% of seniors = 100/200 x 100% = 1/2 x 100% = 50%
(b)
No. of juniors that do not have a job = 34
Total No. = 66 + 34 + 54 + 46 = 200
% of juniors that do not have a job = 34/200 x 100% = 17/100 x 100% = 17%

Please answer :D pretty simple for math experts I’m just bad
Answers
Answer: 74 inches
Step-by-step explanation:
Since we are given the equation of the regression line for the son's height y to be:
y = 0.5x + 38
where,
x = father's height = 72 inches
Then, we put the value of x into the equation and this will be:
y = 0.5x + 38
y = 0.5(72) + 38
y = 36 + 38
y = 74 inches
Therefore, the son is 74 inches.

Find the slope of the line tangent to the function y=6-3x at the point (5,0)
Answers
Answer:
-3
Step-by-step explanation:
To get the slope of the line tangent to the function y = 6 - 3x
First, we need to differentiate;
dy/dx = 0 -3x^{1-1}
dy/dx = 0 - 3x^0
dy/dx = 0 - 3
dy/dx = -3
Hence the slope of the line tangent to the function at the point is -3

Solve the system of linear equations by elimination. Show your work
2x-y=-3
4x + 3y = -21
Answers
Answer:
x = -3, y = -3
Step-by-step explanation:
Solve the following system:
{-y + 2 x = -3 | (equation 1)
3 y + 4 x = -21 | (equation 2)
Swap equation 1 with equation 2:
{4 x + 3 y = -21 | (equation 1)
2 x - y = -3 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{4 x + 3 y = -21 | (equation 1)
0 x - (5 y)/2 = 15/2 | (equation 2)
Multiply equation 2 by 2/5:
{4 x + 3 y = -21 | (equation 1)
0 x - y = 3 | (equation 2)
Multiply equation 2 by -1:
{4 x + 3 y = -21 | (equation 1)
0 x+y = -3 | (equation 2)
Subtract 3 × (equation 2) from equation 1:
{4 x+0 y = -12 | (equation 1)
0 x+y = -3 | (equation 2)
Divide equation 1 by 4:
{x+0 y = -3 | (equation 1)
0 x+y = -3 | (equation 2)
Collect results:
Answer: x = -3, y = -3

find the radius of a circle if the circumference is 66cm
Answers
Answer:
Approximately 10.5, or 10.5095541.
Step-by-step explanation:
To find the radius given the circumference of a circle, we first have to divide the circumference by pi, or an estimation of 3.14. This will give us the diameter.
Since we know that the radius of a circle is simply half the diameter, we divide the number we got from the problem above by 2. This will give you your answer!
Answer:
r = 10.50
Step-by-step explanation:
Circumference =
[tex]2\pi \: r[/tex]
[tex] 66 = 2\pi \: r[/tex]
[tex] \frac{66}{2\pi} = r[/tex]
r = 10.5
Find the volume of a sphere with a radius of 9 inches. Use 3.14 for π. Round your answer to the nearest tenth..
Answers
To find the volume of a sphere, you first must identify the formula: (4/3)pi(r)^3
You’re given the radius 9 inches
And you’re also given the pi approximation 3.14.
With that in mind, we can plug those variables in the formula to get:
(4/3)(3.14)(9in)^3 = 3053.63 in^3
And rounded to the tenths place:
3053.6 in^3

Answers
Answer: -157,464
Step-by-step explanation:
an=a^1*r^n-1
a10=8*-3^10-1
a10=8*-3^9
a10=8*-19683
a10=-157464
Answer:
a10 = -157,464
Step-by-step explanation:
a1 = 8
a2 = -24
r = a2/a1 = -3
an = a1 × r^(n - 1)
a10 = a1 × (-3)^(10 - 1)
a10 = 8 × (-3)^(9)
a10 = -157,464
