Answer:
50 cents per lollipop
Step-by-step explanation:
The full bag of lollipops costs 5.99 for 12 lollipops. You must use proportions.
5.99. _ X
———. ——
12. 1
Cross multiply to get 5.99 = 12x. Isolate the variable (x) by dividing by 12. 5.99/12 = 0.499166666666667
Because it is a price, round to the nearest hundredth and it costs about 50 cents per lollipop
Answer: B
To find the frequency of students favorite sport you will use the equation
Number of students for each sport/total students
Basketball: 4/25 = .16
Football: 7/25 = .28
Lacrosse: 3/25 = .12
Soccer: 8/25 = .32
Volleyball: 3/25 = .12
Answer:
Step-by-step explanation:
I have this saved on my computer in notepad b/c this type of question get asked sooo often :/
point P1 (-4,-2) in the form (x1,y1)
point P2(3,1) in the form (x2,y2)
slope = m
m = (y2-y1) / (x2-x1)
My suggestion is copy that above and save it on your computer for questions like this
now use it
Point 1 , P1 = (2,-4) in the form (x1,y1)
Point 2 , P2 = (4,-1) in the form (x2,y2)
m = [ -1-(-4) ] / [ 4-2]
m = (-1+4) / 2
m = 3 / 2
so now we know the slope is 3/2 :)
Answer:
1.4
Step-by-step explanation:
We have been given that the number of raisins in a box of a popular cereal is normally distributed, with a mean of 133 raisins per box and a standard deviation of 10 raisins. My cereal box has 147 raisins.
To find the z-score for this box of cereal, we will use z-score formula.
, where,
z = Z-score,
x = Sample score,
= Mean,
= Standard deviation.
Upon substituting our given values, we will get:
Therefore, the z-score for this box of cereal is 1.4.
Answer:
Option B.
Step-by-step explanation:
If the cost of the house (y) is in thousands and area of the house is x ft².
Cost of the house is modeled by the equation given,
y = 0.06x + 60.5
By substituting the values in the line of best fit,
235 = 0.06x + 60.5
0.06x = 235 - 60.5
0.06x = 174.5
x = 
x = 2908.33 ft²
x ≈ 2900 ft²
Therefore, Option B will be the correct answer.
