Answer:

Jessie hiked at a constant rate of 3 miles/hour

Step-by-step explanation:

Constant rate can also be called speed

The formula for constant rate /Speed = Distance (miles)/ time in hours

Distance = 1 mile

Time = 20 minutes

Converting to hours

60 minutes = 1 hour

20 minutes =

20/60

= 0.3333333333hour

Constant rate = 1mile/0.3333333333 hour

= 3.0000000003

= 3 miles/hour

The heights of students at a college are normally distributed with a mean of 175 cm and a standard deviation of 6 cm. One might
frosja888 [35]

Answer:

25

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 175cm

Standard deviation = 6 cm

Percentage of students below 163 cm

163 = 175 - 2*6

So 163 is two standard deviations below the mean.

By the Empirical rule, 95% of the heights are within 2 standard deviations of the mean. The other 100-95 = 5% are more than 2 standard deviations of the mean. Since the normal distribution is symmetric, 2.5% of them are more than 2 standard deviations below the mean(so below 163cm) and 2.5% are more than two standard deviations above the mean.

2.5% of the students have heights less than 163cm.

Out of 1000

0.025*1000 = 25

25 is the answer

In circle K, what is the value of x?
djyliett [7]

Answer:

18°

Step-by-step explanation:

A diameter cuts a circle into two arcs that are each 180°. An inscribed angle that intercepts an arc of 180° has a measure of 90°. Thus we have ...

... 5x = 90°

.. 90°/5 = x = 18°
