Which expression represents the same solution as (4) (negative 3 and StartFraction 1 over 8 EndFraction? (4) (negative 3) + (4)

elena-s [515]

Answer:

Option B.

Step-by-step explanation:

The given expression is

$(4)(-3\dfrac{1}{8})$

We need an expression Which represents the same solution as the given expression.

It can be written as

$(4)[-(3+\dfrac{1}{8})]$

$(4)[-3-\dfrac{1}{8}]$

$(4)(-3)+(4)(-\dfrac{1}{8})$

Since $(4)(-3)+(4)(-\dfrac{1}{8})$ is equivalent to given equation, therefore this equation represents the same solution as the given expression.

Hence, option B is correct.

Mariana averaged 80 on her first three math exams. The first score was 86. The second score was 74. What was the third exam scor

Anna71 [15]

The three scores are 86, 74, and an unknown score x. The average (i.e. the sum divided by how many there are) is 80, so we have

$\dfrac{86+74+x}{3}=80$

Multiply both sides by 3 and you get

$160+x=240$

Subtract 160 from both sides to get

$x=240-160=80$

Note: you could solve this exercise very quickly if you notice that the two numbers, 86 and 74, are symmetrical with respect to 80, which is the average. So, the third number must be the average.

Applicants who wish to be admitted to a certain professional school in a large university are required to take a screening test

Elden [556K]

Answer:

Probability of eligible applicants who pass the exam is 0.665

probability of applicants who are ineligible but pass the exam 0.063

Step-by-step explanation:

Total percentage eligible applicants who pass the exam

$\textrm {89\% of 70\%}= \dfrac{89\times70}{100}=62.3\%$

Total ineligible applicants who pass the exam

$\textrm {14\% of 30\%}= \dfrac{14\times30}{100}=4.2\%$

All applicants who pass this exam 62.3% + 4.2% = 66.5%

Probability of applicants who pass the exam

$\textrm{probability }= \dfrac{66.5}{100}=0.665$

Out of 66.5% applicants who pass the exam , 4.2% applicants are ineligible

$\textrm{so the probability is}\dfrac{4.2}{66.5}=0.063$

Probability of applicants who pass the exam is 0.665

probability of applicants who are ineligible but pass the exam 0.063
