Yesterday, Juana sold 84 hot chocolate during her shift at work. If she worked from 7:00 am to 3:00 pm with an hour break for lu

spin [16.1K]

She worked from 7 AM to 3 PM meaning she worked a total of 9 hours. However, since she had an hour lunch break, she only worked 8 hours. 84 divided by 8 is equal to 10.5.

So she sold an average of 10.5 hot chocolates an hour.

Hope this helps! :)

1.Find Each of the following angle measures. Round your answer to the nearest degree. Show your work in the space below

Marysya12 [62]

Answer:

a. m<DAB = 36°

b. m<B = 54°

c. m<C = 74°

Step-by-step explanation:

a. m<DAB = m<CAB + m<CAD

m<DAB = 20° + 16° (substitution)

m<DAB = 36°

b. m<B = 180° - (90° + m<DAB)

m<B = 180° - (90° + 36°) (substitution)

m<B = 54°

c. m<C = 180° - (90° + m<CAD)

m<C = 180° - (90° + 16°) (substitution)

m<C = 74°

Question 6 Unsaved

Andreyy89

Question (6)

To answer this question we will find out both probabilities one by one and then we will multiply both probabilities.

Probability of getting a number card from standard deck will be

$\frac{9\cdot 4}{52}=\frac{36}{52}$

Probability of getting one ace will be $\frac{4}{51}$ as we are given that second card is drawn without replacement.

To find the probability of choosing a number card and then an ace without replacement will be,

$=\frac{4}{51}\cdot \frac{36}{52}=\frac{36}{13\cdot 51}\\
\\
=\frac{12}{13\cdot 17}=\frac{12}{221}$

Therefore, first option is the correct choice.

Question (7)

Let us find out probability that Shironda will get an even number after rolling a cube. We know that a standard dice contains 3 even and 3 odd numbers.

Probability of getting an even number = $\frac{3}{6}=\frac{1}{2}$ .

Now let us find out probability of getting a black card from the deck.

Probability of getting a black card,

= $\frac{2\cdot 13}{52}=\frac{26}{52}=\frac{1}{2}$

Now we can get probability of getting an even number and a black card by multiplying both probabilities.

$\frac{1}{2}\cdot \frac{1}{2}=\frac{1}{4}$

Therefore, probability of getting an even number and a black card is 1/4.
