IS A PICTURE!!!! thank you for your time
Answer:
I am not sure, but I think you would check for the side with the longest length(hypothenuse) and check if the formula of a^2+b^2=c^2(side with the longest length) satisfies it.
A newsgroup is interested in constructing a 90% confidence interval for the proportion of all Americans who are in favor of a new Green initiative. Of the 533 randomly selected Americans surveyed, 351 were in favor of the initiative. Round answers to 4 decimal places where possible.
Answer:
The 90% confidence interval for the proportion of all Americans who are in favor of a new Green initiative is (0.6247, 0.6923).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
Of the 533 randomly selected Americans surveyed, 351 were in favor of the initiative.
This means that [tex]n = 533, \pi = \frac{351}{533} = 0.6585[/tex]
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6585 - 1.645\sqrt{\frac{0.6585*0.3415}{533}} = 0.6247[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6585 + 1.645\sqrt{\frac{0.6585*0.3415}{533}} = 0.6923[/tex]
The 90% confidence interval for the proportion of all Americans who are in favor of a new Green initiative is (0.6247, 0.6923).
Three numbers are in the ratio 5 :3 : 2. If the sum of their squares is 5472, find the three numbers
Answer:
60 36 24
Step-by-step explanation:
5 3 2
25x +9x + 4x = 5472
38x = 5472
x = 144
25(144) = 3,600 9(144) = 1,296 4(144) = 576
60² = 3,600 36²= 1,296 24² = 576
3,600 + 1,296+576 = 5,472

What is 5C3?
A. 35
B. 10
C. 14
D. 28
Answer: B. 10
-5C3 or 5 choose 3 refers to how many combinations are possible from 5 items, taken 3 at a time. To calculate combinations, we will use the formula nCr = n! / r! ... * (n - r)!, where n represents the total number of items, and r represents the number of items being chosen at a time.
-10 is the total number of all possible combinations for choosing 3 elements at a time from 5 distinct elements without considering the order of elements in statistics & probability surveys or experiments. The number of combinations for sample space 5 CHOOSE 3 can also be written as 5C3 in the format of nCr or nCk.

Reflect P (-5,10) over the x-axis. What are the coordinates of the reflected point? What quadrant is the reflected point in?
Answer:
(-5,-10)
it is in quadrant 3 (quadrant III)
Step-by-step explanation:
Mark as Brainliest
Answer:
(-5,-10) In Quadrant III
Step-by-step explanation:
When reflecting a point accross the x-axis, the y-coordinate of the point changes signs
Ex. Positive to Negative and vice versa
Therefore, (-5,10) reflected accross the x-axis becomes (-5,-10)
Since both x and y coordinates are negative, the point falls in the third quadrant, or Quadrant III

Answers:
cos(A) = 0.8480
tan(B) = 1.6
=============================================
Explanation:
Before we can compute cos(A), we'll need to find the hypotenuse.
Use the pythagorean theorem.
a^2 + b^2 = c^2
8^2 + 5^2 = c^2
89 = c^2
c^2 = 89
c = sqrt(89)
The hypotenuse is exactly sqrt(89) units long.
This will allow us to find the cos(A) value
cos(angle) = adjacent/hypotenuse
cos(A) = AC/AB
cos(A) = 8/sqrt(89)
cos(A) = 0.84799830400509 which is approximate
cos(A) = 0.8480 when rounding to four decimal places
-------------------------
For the tangent ratio, we won't use the hypotenuse. Instead, we use the opposite and adjacent sides like so:
tan(angle) = opposite/adjacent
tan(B) = AC/BC
tan(B) = 8/5
tan(B) = 1.6

What is the volume of this composite solid?
Step-by-step explanation:
5×9×12=540
6×9×12÷2=324
324+540=864
Answer:
C. 1188 cubic meters
Step-by-step explanation:
"To find the volume, we must multiply the length x width x height"
The shape is too big so we must break it into another shape
Let's solve the bottom shape that looks like a rectangle!
Length: 12 m
Width: 9 m
Height: 5 m
Volume = 540 m
Now the top shape!
Length: 12 m
Width: 9 m
Height: 6 m
Volume = 648 m
Now we need to add both of the volume shapes!
648 + 540 = 1188 cubic meters
What equation models the volume for a rectangular prism that is 4 cm long, 4cm wide, and 0.1 m tall A. V = 42 x 10 B. V = 10 x (4 + 4) C. V = 400 x 4 D. V = (4 x 4) + 10
Answer:
It's 160
I think you have a typo in d. If you do, the answer is d) V=(4 x 4) x 10
meaning a x 10 versus a + 10 as typed.
Step-by-step explanation:
.1m=10cm
volume = 4 x 4 x 10 = 160

Two trains leave stations 456 miles apart at the same time and travel toward each other. One train travels at 105 miles per hour while the other travels at 105miles per hour. How long will it take for the two trains to meet?
Answer:
let x=distance 105 mph train traveled
(456-x)=distance 85 mph train traveled
Travel time = distance/speed (equal in both directions)
x/105=(456-x)/85
85x=105*456-105x
190x=105*456
x=105*456/190=252 miles
travel time=252/105=2.4 hrs
ans:
The two trains will meet in 2.4 hrs
