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:
angle x equals 25
Step-by-step explanation:
130 + 25 = 155
180 - 155 = 25
Triangles always add up to 180°
Answer: C) 25
Step-by-step explanation:
x²+10x+ __=16+ __
Only the square of 5, 5², which is 25, can make the two factors plus equal to 10x, so we need to add 25.
Since they give you the graph find the highest point in the curved line:
the line touches the number 100
so it's maximum height is 100 feet
now from where it touches 100 look at the time:
it hits 100 feet at 2.5 seconds
