A recipe that makes 8 jumbo blueberry muffins calls for 1 1/2 teaspoons of baking powder how much making baking powder is needed

nirvana33 [79]

we know that

For make $8$ jumbo blueberry muffins is needed $1\frac{1}{2}$ teaspoons of baking powder

$1\frac{1}{2}=1.5$

by proportion

$\frac{8}{1.5} =\frac{36}{x} \\ \\ 8x=36*1.5\\ \\ x=\frac{36*1.5}{8} \\ \\ x=6.75$

$x=6\frac{3}{4}$ teaspoons of baking powder

therefore

the answer is

$6\frac{3}{4}$ teaspoons of baking powder

A box contains four red balls and eight black balls. Two balls are randomly chosen from the box, and are not

castortr0y [4]

P(B) = 8/12

P(R | B) = 4/11

P(B ∩ R) = 8/33

The probability that the first ball chosen is black and the second ball chosen is red is about 24% percent

<em><u>Solution:</u></em>

<em><u>The probability is given as:</u></em>

$Probability = \frac{\text{number of favorable outcomes}}{\text{total number of possible outcomes}}$

Given that,

A box contains four red balls and eight black balls

Red = 4

Black = 8

Total number of possible outcomes = 12

Let event B be choosing a black ball first and event R be choosing a red ball second.

$P(B) = \frac{8}{12}$

$P(B n R) = P(B) \times P(R)\\\\P(B n R) = \frac{8}{12} \times \frac{4}{11}\\\\P(B n R) = \frac{8}{33}$

<h3><u>Find </u><u> P(R | B)</u></h3><h3> $P(R | B) = \frac{P(R n B)}{P(B)}\\\\P(R | B) = \frac{\frac{8}{33}}{\frac{8}{12}}\\\\P(R | B) = \frac{8}{33} \times \frac{12}{8}\\\\P(R | B) = \frac{4}{11}$ </h3>

<em><u>The probability that the first ball chosen is black and the second ball chosen is red is about percent</u></em>

$\frac{8}{33} \times 100 = 0.24 \times 100 = 24 \%$

Thus the probability that the first ball chosen is black and the second ball chosen is red is about 24% percent
