y = kx
'k' is the constant of proportionality, or otherwise known as constant of variation.
y = 90
x = 3
90 = k(3)
90 = 3k
3k/3 = 90/3
k = 30
The constant of proportionality is 30.
Answer:
You can get 2 pounds of pecan for the cost of 22$
Step-by-step explanation:
if 3 pounds of pecan cost 33$ that means 1 Pound of pecan cost 11$ So if there is three pound of pecan that means it cost 33$ like it says in the question, so for the price of 22$ you can get two pecans.
First we should write the total numbers:
12+8+6+4=30
then we should divide the number 30 by 360(because the pie chart is 360 degrees):

now we should multiply 12(the number of students who likes rock) by 12

the answer is 144 degrees
So Sally gets payed <span>$32,448 a year and gets paid the same amount each week. To figure how much she gets payed a week, divide her salary by 52 weeks since there are 52 weeks in a year. Then we divide how much she makes a week by 40 to see how much she gets payed an hour since she works 40 hours each week:
</span><span>32,448/52 = 624
624/40 = 15.6
Sally makes $15.60 an hour.
</span>
We can rewrite (z ≤ −1.75) in order to 4%.
We have given that (z ≤ −1.75).
We have to use the Normal Distribution is symmetrical
<h3>What is the Normal Distribution is symmetrical?</h3>
The normal distribution is symmetric and has a skewness of zero.





That is nothing but the 4%
