Answer:
4' - 9.64
Step-by-step explanation:
Total rise = 2' - 7"
Total run = 3' - 9"
Converting to inches :
1' = 12" ; 1 feet = 12 inches
2' = 2 * 12 = 24"
3' = 3 * 12 = 36"
Total rise = 24" + 7" = 31"
Total run = 36" + 9" = 45"
Length of stringer = hypotenus
Hypotenus = √(total rise² + total run²)
Hypotenus = √(31² + 45²)
Hypotenus = 54.644304"
= 4' - 9.64"

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

Answer:
x = 148
Step-by-step explanation:
vertical angles are congruent
the angle with a measure of 148° and the angle labeled "x" are vertical angles.
Hence, x = 148
Answer:
x=148 because the opposite angles are equal
also, the rest of the smaller angles are both 32 degrees if you need them
you can check because 148+148+32+32=360
hope it helps:)

What is the volume of this figure? Pls help this is due Thursday 11:45
Answer:
The answer for this question is 49 cubic inches
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
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

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
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).
