3/4+ (1/3 divided by 1/6) - (- 1/2)

Virty [35]

Answer:

3 1/4

Step-by-step explanation:

3/4 + (1/3 divided by 1/6) - (- 1/2)

first calculate between the brackets.

(1/3) / (1/6)

Division is the inverse of multiplying.

(1/3) * (6/1)

multiply both numerators and multiply both denominators

1*6 / 3*1 = 6/3 = 2

3/4 + (2) - (- 1/2)

make all denominators into 4

3/4 + (8/4) - (- 2/4)

- ( - = plus

3/4 + (8/4) + 2/4

3/4 + 8/4 + 2/4

add all numerators since the denominators are all the same.

( 3 + 8 + 2 ) / 4

13/4

3 1/4

What is an equation of the line that passes through the points (-4, -1)(−4,−1) and (6, -1)(6,−1)?

Vlada [557]

$\boxed{y=-1}$

<h2>Explanation:</h2>

In order to solve this problem, let's remember the point-slope form of the equation of a line:

$y-y_{1}=m(x-x_{1}) \\ \\ m:slope \\ \\ (x_{1},y_{1}):A \ point \ on \ the \ line$

We know two points:

$(x_{1},y_{1})=(-4, -1) \\ \\ (x_{2},y_{2})=(6, -1)$

So:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ m=\frac{-1-(-1)}{6-(-4)} \\ \\ m=0$

So this is a constant line (slope equals zero). Therefore, every point has a y-coordinate $y=-1$ . In other words, the equation is:

$\boxed{y=-1}$

To the nearest whole percent, what is the probability that a randomly chosen member of the JV swim team does not wear glasses an

Yuri [45]

Answer: 14%

Step-by-step explanation:

Complete question is provided in the attachment below:

Probability that members of the junior varsity swim team wear glasses = 55%=0.55

Given: P(wear glasses) = 0.55

P(not wear glasses) = 1-0.55 = 0.45

P(member in 10th grade | not wear glasses) = 30%

Using conditional probability formula:

$P(B|A)=\dfrac{P(A\text{ and } B)}{P(A)}$

$\Rightarrow\ 0.30=\dfrac{P(\text{not wear glasses and in 10th grade})}{0.45}\\\\\Rightarrow\ P(\text{not wear glasses and in 10th grade})=0.45\times0.30\\\\0.135=13.5\%\approx14\%$

Hence, the probability that a randomly chosen member of the JV swim team does not wear glasses and is in the 10th grade = 14%.

So, the correct option is "14%".
