Bonnie and Adele wrote down how much they spent at play rehearsal each week for 6 weeks.

liq [111]

Ok, if you want to find out the range of the hours they play, here it is:

Since the number of hours for Bonnie are 4, 5, 4, 3, 3, 5, the range should be 3, 4, 5, which makes the range 3.

Since the number of hours for Adele are 5, 5, 9, 8, 8, 7, the range should be 5, 7, 8, 9, which makes the range 4.

Which means Adele's range is bigger than Bonnie's!

I need help on my math question so whats c?

Vanyuwa [196]

Answer:

c = -25

Step-by-step explanation:

Multiply the denominator by -7 on both sides, you would then get the equation c + 32 = 7 in which the -7 on the left side cancels out. Subtract 32 on both sides to get the c value which is -25.

-12=3+3u Solve for “u”

Kipish [7]

Answer:

$- 12 = 3 + 3u \\ 3 + 3u = - 12 \\ 3u = - 12 - 3 \\ 3u = - 15 \\ u = \frac{ - 15}{3} \\ u = - 5$

u = -5

The probability that a morning bus arrives on time is 65%.

Drupady [299]

The attached diagram represents the tree diagram for three consecutive mornings.

<h3>How to draw the tree diagram?</h3>

The probability of arriving on time is given as:

P(On Time) = 65%

Assume that the bus would definitely show up.

Then it means that the event is a binomial event and the possible outcomes are:

On Time and Late

The above means that the number of possible outcomes is 2.

For three consecutive mornings, the total outcome is:

Total = 2³

Evaluate

Total = 8

This means that the tree diagram would have 8 outcomes

Next, we draw the tree diagram (see attachment)
