a snowplow has maximum speed of 40 miles per hour on a dry highway. It's maximum speed decreases by 1.2 miles per hour for every
vova2212 [387]

Step-by-step explanation:

The snowplow's speed is 40 mph minus the loss from the snow, which is 1.2 mph times the depth of snow in inches.

y = 40 − 1.2x

When y = 0:

0 = 40 − 1.2x

1.2x = 40

x = 33 ⅓

The snowplow stops moving when the snow is 33 ⅓ inches deep or more.

An article reported that for a sample of 55 kitchens with gas cooking appliances monitored during a one-week period, the sample
Sati [7]

Answer:

Step-by-step explanation:

Given that

sample size n = 55:  x bar = 654.16 and s = sample sd = 162.34

Std error = 162.34/sqrt 55 = 21.889

For 95% CI we can use t critical value as population std dev is not known.

df = 54

t critical = 2.004

Margin of error = 2.004 *21.889 = 43.866

Confidence interval lower bound = 654.16-43.866 =610.294

Upper bound = 654.16+43.866=698.026

Confidence interval rounded off at 95% = (610.29, 698.23)
