Answer:

7/8

Step-by-step explanation:

If you mean 7/20 divided by 2/5 and there both fractions its like this:

Since we are dividing we flip 2/5 to 5/2.

Then we multiply 7/20 by 5/2. 7 times 5 is 35 and 20 times 2 is 40. So it is 35/40. You simplify by dividing by 5 and your final answer is 7/8.

At noodle & company restaurant, the probability that a customer will order a nonalcoholic beverage is .46. Find the probabil

skelet666 [1.2K]

Answer:

0.0021

Step-by-step explanation:

Given:

Probability of ordering a nonalcoholic beverage is, $P(N)=0.46$

Number of samples are $n=10$

Now, the complement of event 'N' is not ordering a nonalcoholic beverage.

Therefore, $P(\overline N)=1-P(N)=1-0.46=0.54$

Now, for a sample of '10' customers, the probability of not ordering a non alcoholic beverage is product of their individual probabilities as all these events are independent events.

Therefore, probability that none of the 10 will order a nonalcoholic beverage is given as:

$=[P(\overline N)]^{10}\\\\=(0.54)^{10}\\\\=0.0021$

The comeplement of 99

harkovskaia [24]

1. the complement is when two angles add up to 99 degrees and the supplement is when the two angles add up to 180 degrees.

2. Let x be the measure of the unknown angle .

3. Let 90 -x be it's complement and 180- x be the supplement of the angle .

4. Given 90-x=3x+9 the measure of the complement of an angle is 3x+9. Solve using the following steps.

99-x=3x+9
Add x-9 to both sides to isolate x-terms on right side and numbers on left
90-x+x-9=3x+9+x-9

90-x+x-9=3x+9+x-9

91=4x
divide by 4 to both sides yields
91/4=x

5. Given 3x+99=180-x. The measure of the supplement of an angle is 3x+99. So
3x+99=180-x

Add x+99 to both sides of equations to isolate x on right side and number on left
3x+99+x-99=180-x+x-99

4x=91

X=91/4

6. The angle is x=91/4
