What is the length, in centimeters (cm), of y?
Answer:
Step-by-step explanation:
Use Pythagorean Theorem for a right triangle.
a^2 + b^2 = c^2
3.6^2 + 4.8^2 = c^2
c = 6cm
The length of y (Hypotenuse) is 6 cm.
We have,
Perpendicular = 3.6 cm
Base = 4.8 cm
Hypotenuse = y
Using Pythagoras theorem
Hypotenuse² = Base² + Perpendicular²
So, y² = 4.8² + 3.6²
y²= 23.04+ 12.96
y²=
y= √36
y= 6 cm
Thus, the value of y (Hypotenuse) is 6 cm.

Which of the following types of statement cannot be used to explain the
steps of a proof? Check all that apply.
A. Conjecture
B. Guess
OC. Postulate
0 D. Theorem
Answer:
A. Conjecture
B. Guess
Steps of a proof cannot be explained using A. conjecture and B. guess.
What is Conjecture?Conjectures in mathematics is a term which is given to the situation where something is guessed without any proof or basics.
This may be true, but are not proved up to this day.
Theorems are something which are already proved. This can be used in figuring out the proof of any problems.
Similarly, postulates are something which are the special cases of a certain proof. These can also be used to prove anything in mathemetics.
But guess and conjectures are not already proved statements. So these cannot be used.
Hence the options are Guess and Conjectures.

70%of it is 14 min find the valy ofx
Note:
Your questions sound a little unclear.
But, I am assuming your questions as:
''70% of x is 14 min. Find the value of x''.
So, I will solve assuming this statement which anyways would clear your concept.
Answer:
The value of x = 20.
Step-by-step explanation:
Given
''70% of x is 14 min. Find the value of x''.
Thus,
70% of x = 14
70/100 × x = 14
0.7x = 14
divide both sides by 0.7
0.7x/0.7 = 14/0.7
x = 20
Therefore, we conclude that the value of x = 20.

Suppose a 99% confidence interval for the mean weight of high school girls in pounds is (102.3, 106.5). If we had measured the weights of each of the girls in kilograms (2.2 pounds = 1 kilogram) then the confidence interval for the mean weight of high school girls in kilograms would have been
Answer:
The confidence interval for the mean weight of high school girls in kilograms would have been would have been (46.5, 48.41).
Step-by-step explanation:
To find the interval, we can just make the conversion of the values from pounds to kilograms.
Each kilogram has 2.2 pounds. So, to realize the conversion from pounds to kilograms, we divide by 2.2.
Confidence interval: (102.3 pounds, 106.5 pounds).
102.3 pounds = 102.3/2.2 = 46.5 kilograms
106.5 pounds = 106.5/2.2 = 48.41 kilograms
The confidence interval for the mean weight of high school girls in kilograms would have been would have been (46.5, 48.41).

Automobile engines and transmissions are produced on assembly lines, and are inspected for defects after they come off their assembly lines. Those with defects are repaired. Let X represent the number of engines, and Y the number of transmissions that require repairs in a one-hour time interval. The joint probability mass function of X and Y is as follows: y x 0 1 2 3 0 0.13 0.10 0.07 0.03 1 0.12 0.16 0.08 0.04 2 0.02 0.06 0.08 0.04 3 0.01 0.02 0.02 0.02 Find the marginal probability mass function of X. Round the answers to two decimal places. pX(0) pX(1) pX(2) pX(3)
Answer:

Step-by-step explanation:
From the question we are given the table
[tex]\begin\\\begin{tabular}{|l|l|l|l|l|} &&y \\x &0&1&2&3\\0 &0.13&0.1&0.07&0.03 \\1&0.12&0.16&0.08&0.04\\ 2&0.02&0.06&0.08&0.04\\ 3&0.01&0.02&0.02&0.02\end[/tex]
Generally the marginal probability mass function of X is mathematically given as
[tex]P(x)=\sum P(x,y)>y[/tex]
[tex]\sum P(0)=0.13+0.1+0.07+0.03=0.33\\\sum P(1)=0.12+0.16+0.08+0.04=0.40\\\sum P(2)=0.02+0.06+0.08+0.04=0.20\\\sum P(3)=0.01+0.02+0.02+0.02=0.07[/tex]
Therefore marginal probability mass function of X

Zachary purchased a computer for $1,400 on a payment plan. Two months after he purchased the computer, his valence was $1,120. Three months after he purchased the computer, his balance was $980. What is an equation that models the balance y after x months??
9514 1404 393
Answer:
y = 1400 -140x
Step-by-step explanation:
In the first two months, Zachary paid ...
1400 -1120 = 280
so 280/2 = 140 per month. This is the amount that the balance decreases each month from the starting balance of $1400.
Zachary's balance (y) can be modeled as ...
y = 1400 -140x
