Its C! Lets say x=30
|30-323|=50
This could technically be true because it would show if the temp is within range
Answer:
first and third
Step-by-step explanation:
Emma used the product instead of the quotient and forgot the parentheses in x-4.5
Required experession is g(5000) = 50
Answer:
Step-by-step explanation:
Both 115 and 145 mph are above the mean. Draw a normal curve and mark these speeds. 115 mph is 1 standard deviation above the mean; 130 would be 2 standard deviations above the mean; and 145 would be 3 s. d. above it.
We need to find the area under the standard normal curve between 115 and 145. This is equivalent to the area under the standard normal curve between z = 1 and z = 3.
I used my TI-83 Plus calculator's DISTR function "normalcdf(" to calculate this area: normalcdf(1, 3) = 0.1573.
The area between z = 1 and z = 3 is 0.1573. In other words, the percentage of serves that were between 115 and 145 mph was 15.73%.
yes, to complete her goal she would need to run roughly 14.3 so this is more than enough
