What is the hypotenuse and how do I get it?
Step-by-step explanation:
by Pythagoras theorem:
perpendicular² + base²= hypotenuse²
(1/√2)²+ (1/√3)² = H²
1/2+1/3= H²
5/6 = H²
√(5/6 )= H
√5/√6 = H

7.2.9-T Question Help Here are summary statistics for randomly selected weights of newborn girls: n= 157, x = 33.6 hg, s = 6.2 hg. Construct a confidence interval estimate of the mean. Use a 98% confidence level. Are these results very different from the confidence interval 32.3 hg
Answer:
The 98% confidence interval estimate of the mean is between 32.45 hg and 34.75 hg.
32.3 is not a part of the confidence interval, which means that yes, these results are very different from the confidence interval 32.3 hg
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.98}{2} = 0.01[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.01 = 0.99[/tex], so Z = 2.327.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
[tex]M = 2.327\frac{6.2}{\sqrt{157}} = 1.15[/tex]
The lower end of the interval is the sample mean subtracted by M. So it is 33.6 - 1.15 = 32.45 hg
The upper end of the interval is the sample mean added to M. So it is 33.6 + 1.15 = 34.75 hg
The 98% confidence interval estimate of the mean is between 32.45 hg and 34.75 hg.
Are these results very different from the confidence interval 32.3 hg
32.3 is not a part of the confidence interval, which means that yes, these results are very different from the confidence interval 32.3 hg

A total of P60,000 was invested, a portion at 5% and the remainder at 4.5%. The total amount of interest earned was P2,900. How much was invested at each rate?
Answer:
P40000 at 5%
P20000 at 4.5%
I am curious as to what the P stands for. Can you tell me?
Step-by-step explanation:
Let x = amt. invested at 5%
y = amt. invested at 4.5%
(1) x + y = 60000 (2) .05x + .045y = 2900
50x + 45y = 2900000
-45 times (1) -45x - 45y = -2700000
5x = 200000
x = 40000
40000 + y = 60000
y = 20000
P40000 at 5%
P20000 at 4.5%
I am curious as to what the P stands for. Can you tell me?

Find the equation containing the points (-1,1) and (4,-9)
A
y = 2x + 1
B
y = -2x - 3
C
y = 2x -3
D
y = -2x -1
Plz help
Answer:
D)
Step-by-step explanation:
Substitute it into equation, for (-1,1): -2*(-1) - 1 = 2 -1 = 1, and -2*4 - 1 = - 8 -1 = -9, so D) is correct.

Question 10
The graph of a function includes the points (4, 5) and (21, 39).
What is the rate of change of the function?
A
2
B
34
с
17
D
0.5
Answer:
Step-by-step explanation:
The rate of change, slope, m is
m=(y2-y1)/(x2-x1), we have points (4,5) and (21,39) so
m=(39-5)/(21-4)
m=34/17
m=2
So the rate of change is 2
Erica decides to paint the birdhouse. She has a pint of
paint that covers 32.5 ft2 of surface. How can you tell that Kali has
enough paint without calculating?
Answer:
Step-by-step explanation:
If the birdhouse is a cube that is 2 ft on each edge, the surface area is 6×2² = 24 ft². That's a pretty large birdhouse, and it will need about ¾ of a pint of paint.

Janie walks 1 mile to get to a running track.she then runs at a speed of 3.5 miles per hour.Which linear models represents the total distance she ran and walked, d, as a function of t, the time she runs,in hours?
Answer:
d = 3.5t + 1
Step-by-step explanation:
The linear function would have to multiply the speed she runs at the track by the number of hours that she spent running. Then it should add this amount to the 1 mile that she walked to get to the track. If we use the variable d as the total distance that she ran and walked, and the variable t to represent time then we would create the following linear function/model.
d = 3.5t + 1

Which expression is equivalent to 39 + 91?
3(7 + 13)
3(13 + 30)
7(3 + 13)
13(3 + 7)
Answer:
The last one is the answer
Step-by-step explanation:
39+91=130
13(10)=130
130=130
Answer:
13(3 + 7)
Step-by-step explanation:
First do 3 + 7 and that is 10.
Then do 10 x 13 and that is 130.
Finally compare 91 + 39 = 130 to 13(3 + 7)
