Center:
Radius:
Answer:
Center: (9, 4)
Radius: 20
Explanation:
(x - 9)² + (y - 4)² = 400
The Circle Formula:
(x - h)² + (y - k)² = r²
where (h, k) is center points, r is radius
Rewrite the equation:
(x - 9)² + (y - 4)² = 20²
Identify following:
h = 9, k = 4, radius = 20

Answer:
17Step-by-step explanation:
SINCE THE LINES ARE PARALLEL THEN ANGLE A AND ANGLE B ARE COREESPONDING TO EACH OTHER.A = 7x + 24 B= 3x+ 92A=B7x + 24 = 3x + 927x - 3x = 92 - 24
4x = 68
x = 68 / 4
x =17
Answer:
143
Step-by-step explanation:
These are corresponding angles meaning they are congruent. So we just have to set them equal to each other and solve for x. Then plug in x.
7x + 24 = 3x + 92
subtract 3x from both sides
4x + 24 = 92
subtract 24 from both sides
4x = 68
divide both sides by 4
x = 17
Now plug in x to angle A, which is 7(17) + 24
119 + 24
then add
you get:
143
A local athletic facility offers a four-week training course, hoping to increase athletes’ running speeds. Thirty-five volunteer athletes are timed, in seconds, running a 50-yard dash before the training program begins and then again after the program is complete. The difference in running times (before training – after training) is calculated for each athlete. Are the conditions for inference met?
No. The athletes who volunteered for this study were not randomly assigned a treatment order.
No. The 10% condition is not met.
No. The Normal/Large Sample condition is not met because the sample size is too small.
Yes. All conditions are met.
Using the Central Limit Theorem, it is found that the correct option is given by:
Yes. All conditions are met.
What does the Central Limit Theorem state?It states that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the sampling distribution is also approximately normal, as long as n is at least 30.
In this problem, we have no information about the distribution, but the sample size is greater than 30, hence all the conditions have been met.

Solve for x 5.2³x = 21.
Answer:
D) 0.69
Step-by-step explanation:
Given :
5 × 2³ˣ = 21
Divide by 5 on each side :
1/5 x 5 x 2³ˣ = 1/5 x 212³ˣ = 4.2Taking the cubic root :
∛2³ˣ = ∛4.22ˣ = 1.61Using logarithm values :
log(2ˣ) = log(1.61)x log(2) = log(1.61)x = log (1.61) / log (2)x = log₂ (1.61)x = 0.69 (approximately)Answer:

Step-by-step explanation:
Given equation:

deliver 44 papers. How many papers does Robert deliver each week?
A. 369
B. 325
C. 413
D. 427
Answer:
B. 325
Step-by-step explanation:
y = the total value of the amount of papers he has to deliver each week
44x + 61 = y
(7 days in a week - sunday = 6 days)
44(6) + 61 = y
264 + 61 = y
325 = y

16 cm
24 cm
Answer:
256cm
Step-by-step explanation:
I'm assuming 16 and 16 are the 2 legs of the triangle.
The equation to get the area of a triangle is b x h /2
16cm x 16cm / 2 = 128cm
128cm x 2 triangles = 256cm

Step-by-step explanation:
Splitting this up into 2 prisms, one vertical and the other horizontal:
Volume of each prism = length * width * height:
Volume of the figure =
Horizontal + vertical prism
= 7 * 9 * 50 + 7* 7* 28
= 3150 + 1372
= 4522 mm^3
Answer the volume based Question. I will make uh brainliest + 50 points
Answer:
see explanation
Step-by-step explanation:
(a)
the volume (V) of the cylinder is calculated as
V = πr²h ( r is the radius and h the height ) , then
V = π × a² × 2a = 2a³π
(b)
the volume of the prism is calculated as
V = Ah ( A is the cross- sectional area and h the height ) , then
a²b = 2a³π ( divide both sides by a² )
b = 2πa
