Answer:
95.5°F
Step-by-step explanation:
Given the regression equation :
y = 1.8x - 76.9 ; the relationship between temperature (°F) and number of ice cream sold
y = number of ice cream sold
x = temperature (°F)
The temperature when 95 iccream cones are sold will be ;
Here, y = 95
Using the model :
95 = 1.8x - 76.9
95 + 76.9 = 1.8x
171.9 = 1.8x
Divide both sides by 1.8
171.9 / 1.8 = x
95.5°F = x
Hence, temperature when 95 cones of ice-cream are sold is 95.5°F
Answer:
40 Tickets
80 Tickets
Step-by-step explanation:
To find how many tickets it will take to break even, we use the formula:
Our variables are:
Fixed Cost = $200
Sales Price = $10
Variable Cost = $5
Let's plug in our values into the formula.
So the class needs to sell a total of 40 Tickets to break even.
Since we know that it takes 40 tickets to break even a $200 Fixed cost. To make a profit of $200, we simply multiply the number of tickets sold by 2.
Number of tickets for $200 profit = 40 x 2
Number of tickets for $200 profit = 80 Tickets.
So the class needs to sell 80 Tickets to make a $200 Profit.
Answer:
y = 3x -18 ( where y = balls sent back by Rudolf; x= balls given to Rudolf)
Step-by-step explanation:
x (Balls given) y( Balls sent back)
8 6 Δy/Δx = (27-6)/(15-8) = 3
15 27
25 57 Δy/Δx = (57-27)/(25-15) = 3
Observing the number sequence shows constant gradient and as such we can use equation of a straight line to relate the two variables.
Using the equation of a straight line we have:
(y-y1)/(x-x1) = (y2-y1)/(x2-x1)
y-6/x-8 = (27-6)/(15-8)
y-6/x-8 = 3
y-6 = 3(x-8)
y-6 = 3x - 24
y = 3x-18
Answer:
40.0
18%
14.375%
1/250
38
6325
Step-by-step explanation:
Convert the percent to a decimal 4,000%
4000% = 4000/100 = 40.0
Convert the decimal or whole number to a percent.
0.36 * 1/2
= 0.36/2 * 100
= 0.18 * 100
= 18%
Convert the decimal or whole number to a percent.
1.15 * 1/8
= 1.15/8 * 100
= 14.375%
Convert the percent to a reduced fraction, mixed number, or whole number.
0.4%
= 0.4/100
= 1/250
Solve for the portion (in $). Round to hundredths when necessary.
9 1/2% of $400 = 19/2% x 400
= 0.095 x 400
= 38
Solve for the portion. Round to hundredths when necessary.
What number is 253% of 2,500?
253/100 x 2500
= 2.53 x 2500
= 6325
