Answer: 3 hours

Step-by-step explanation:

From the question, we are informed that WHUR Radio uses 1/5 of its of its 10 hours of daytime broadcast for commercial and 1/2 for music.

Hours used for commercial:

= 1/5 × 10

= 2 hours

Hours used for music:

= 1/2 × 10

= 5 hours

Hours left for news will be:

= 10 hours - 2 hours - 5 hours

= 3 hours

Lynn plotted point G, 3 units to the left and 2 units above point F. Where did lynn plot point G?

kvasek [131]

Answer:

$G = (2,6)$

Step-by-step explanation:

See Attachment for Complete Question

From the attachment, we can see that F is plotted at

$F = (5,4)$

On the x axis, G is 3 units to the left;

And on the y axis, G is 2 units above

So, the coordinates of G is calculated as:

$G = (5-3,4+2)$

$G = (2,6)$

Hence:

<em>G is plotted at (2,6)</em>

A statistics professor drew a random sample of 81 observations and found that x with bar on top equals 62 s equals 15. Estimate

ratelena [41]

Answer:

LCL = 59.26 to two decimal places

Step-by-step explanation:

Here, we want to estimate the LCL of the population mean with 90% confidence

We proceed as follows;

Given alpha = 0.1, then Z(0.05)=1.645 (from standard normal table), s = 15

Mathematically;

LCL =x_bar -Z*s/√( n)= 62 - (1.645 * 15)/√81

LCL = 62- (24.675)/9 = 59.2583

LCL = 59.26 to two decimal places

belka [17]

Answer:

$Percent = 79\%$

Step-by-step explanation:

Given

$Adults = 450000$

$Rate = 79\%$ --- Those that do not get recommended amount of exercise

Required

The percentage that do not get the recommended amount of exercise

From the question, we have 79% to be the percentage of adults that do not get the recommended amount of exercise. This 79% represents the required percentage

Hence:

$Percent = 79\%$
