In order for Brady to earn a B in his biology course, his test scores must average at least 80%. On the first 5 tests, he has an
larisa [96]

Hey there! I'm happy to help!

There were 5 tests needed to make an average of 77. These numbers have to add up to 385 (77×5) because that is what you divide by 5 to find the average which is 77.

Now, we want to find an average of 80 with 6 numbers. We multiply 80 and 6, showing us that the sum of these 6 numbers must be 480. Since 5 of these numbers are the same as with the 77 average, we know that one test score (the one Brady needs to get) is added to 385 to give us 480.

480-385=95

Therefore, Brady needs to earn a 95% on the last test to receive a B in the class.

Students surveyed boys and girls separately to determine whether they wanted outdoor
vazorg [7]

Answer:

111 girls

Step-by-step explanation:

Given

Boys: Every 17 outdoor ≈ 20 indoor

Girls: 3:2 outdoor to indoor

First, we'll determine the ratio of outdoor to indoor for boys;

Recall that;

17 choose indoor while 20 choose outdoor;

The ratio of outdoor to indoor is;

20 : 17

Convert to fraction:

\frac{20}{17}

Let x represent number of boys that choose indoor when 85 boys chose outdoor;

The ratio of outdoor to indoor is;

x : 85

Convert to fraction

\frac{x}{85}

Equate both fractions

\frac{20}{17} = \frac{x}{85}

Multiply both sides by 85

85 * \frac{20}{17} = \frac{x}{85} * 85

85 * \frac{20}{17} = x

\frac{1700}{17} = x

100 = x

x = 100

This implies that when 85 chose outdoor, 100 chose indoor for boys;

Total = 100 + 85

Total = 185 boys surveyed

<em>Recall that the question says the same number of boys and girls were surveyed</em>

This implies that

Total Girls Surveyed = 185

For the girl ratio;

Outdoor to Indoor= 3:2

Number of girls that chose outdoor is as follows;

Outdoor = \frac{3}{3 + 2} * Total

Outdoor = \frac{3}{3 + 2} * 185

Outdoor = \frac{3}{5} * 185

Outdoor = \frac{555}{5}

Outdoor = 111

<em>Hence, the number of girls that chose outdoor is 111</em>
