The answer is 14.5 degrees because and acute triangle is less than 90 degrees and you subtract 75.5 from 90 and you get 14.5. Hope I helped you

Answer:

Step-by-step explanation:

When you roll dice, there are 6 possible outcomes.

In order to not roll a 6, you'd have to roll either 1,2,3,4,5.

So you have a 5:6 chance of not rolling a 6.

But they're asking you to use the chart.

Based on the chart, you've rolled the die 24+10+8+3+30+15=90 times.

Of those 90 times, you rolled a 6 15 times.

Which means you did not roll a 6 90-15=75 times.

Therefore the probability of not rolling a 6, based on the chart, is 75/90=83%.

Notice that 5/6=83% as well. So this chart is fairly accurate.

Now for number 2.

Based on the chart, odd numbers appear 24+8+30=52 times out of the 90.

So we can say that odd numbers show up 52/90=58% of the time.

If James is rolling the cube 250 times, we know odd numbers will show up 58% of the time so, .58*250=144 is how many times we can expect to see an odd number appear.

Perform the indicated operation.(4r/r+3) - (5/r)

Aleks [24]

Answer:

4r² - 5r - 15 / r(r+3)

Step-by-step explanation:

To solve this problem, we will proceed the following way, writing down the common multiple of the denominators.

$\frac{4r}{r+3} -\frac{5}{r} =\frac{4r(r)-5(r+3)}{r(r+3)} =\frac{4r^{2}-5r-15 }{r(r+3)}$

Thus, the answer is 4r² - 5r - 15 / r(r+3)

Find the mean of the list of data.<br> 49, 65, 41, 38, 87, 55, 95, 106<br> I can’t find the answer

KatRina [158]

Answer:

67.

Step-by-step explanation:

First we find the mean:

Mean is add up everything and divide by how much numbers there are.

The numbers are:

$49, 65, 41, 38, 87, 55, 95, 106$ .

So we add them up which is 536.

Then we divide by how much numbers there are.

There are 8 numbers so 536/8 which is 67.

Hope this helps :D
