It's not a typo that both answers are 24
======================================================
Explanation:
Each time the weight goes up by 1 ounce, the cost goes up by 24 cents. So the unit cost is 24 cents per ounce. This is exactly the slope of the line because the slope is the rate of change. It tells us how fast something is changing.
You can use the slope formula to answer this question, but I think it's easier to simply locate the point (1,24) and then note that slope = rise/run = y/x = 24/1 = 24. This shortcut only works because the line goes through the origin.
The equation of this line is y = 24x
x = number of ounces
y = cost in cents
Answer:
$39.22
Step-by-step explanation:
The case costs $37. $37 is 100% of the price of the case.
The tax is 6% of the cost of the case. When you add 6% to 100% you get 106%.
The total price including tax is 106% of the price of the case.
106% of $37 = 1.06 * $37 = $39.22
Answer: $39.22
Answer:
17.55 tubs
Step-by-step explanation:
step 1
Find out the total scoops of ice cream in 234 regular cones and 156 large cones

step 2
Find out the weight of the total scoops
we know that
One scoop of ice cream is 3 ounces
so

step 3
Convert ounces to pounds
Remember that
1 pound = 16 ounces
so
To convert ounces to pounds divide by 16

step 4
Find out how many ice cream tubs Richard used to make the cones
we know that
A tub of ice cream weighs 10 pounds
Divide the total weight in pounds by 10

Answer:
[0.4979, 0.5479]
Step-by-step explanation:
-We first determine the sample proportion:

-The confidence intervals of a sample proportion is calculated using the formula:

#We substitute for the sample proportion and z value to get the Confidence interval:
![CI=\hat p\pm z\sqrt{\frac{\hat p(1-\hat p}{n}}\\\\=0.5238\pm 1.645\times \sqrt{\frac{0.5238\times0.4762}{1008}}\\\\=0.5238\pm0.0259\\\\=[0.4979,0.5497]](https://tex.z-dn.net/?f=CI%3D%5Chat%20p%5Cpm%20z%5Csqrt%7B%5Cfrac%7B%5Chat%20p%281-%5Chat%20p%7D%7Bn%7D%7D%5C%5C%5C%5C%3D0.5238%5Cpm%201.645%5Ctimes%20%5Csqrt%7B%5Cfrac%7B0.5238%5Ctimes0.4762%7D%7B1008%7D%7D%5C%5C%5C%5C%3D0.5238%5Cpm0.0259%5C%5C%5C%5C%3D%5B0.4979%2C0.5497%5D)
Hence, the 90% confidence intervals is [0.4979,0.5479]
