Find the slope of the line parallel to the line graphed. A) -1 B) 0 C) 1 D) undefined

The slope of the parallel line (which has the same slope as the referenced line) line would be undefined, as vertical lines are undefined. Let's test this.

Slope is y2-y1/x2-x1. We'll use the points (2,-5) and (2,5)
5-(-5)/2-2 simplifies to 10/0. Since you can't divide by zero, this is undefined.

In one town, 39% of all voters are Democrats. If two voters are randomly selected for a survey, find the probability that they are both Democrats. Round to the nearest thousandth if necessary.

Answer:

The probability is 0.152

Step-by-step explanation:

We know that in this town 39% of all voters are Democrats. Therefore, the probability of a randomly selected voter being a Democrat is p=0.39

The experiment of randomly select voters for a survey is called a Bernoulli experiment (under some suppositions). We suppose that exist independence in this randomly selection of voters. We also suppose that there are only two possibilities for the voter : It is Democrat or not.

Now the variable X : ''The randomly selected voter for a survey is Democrat'' is a Binomial random variable.

X ~ Bi (n,p)

The probability function for the BInomial random variable X is :

P(X=x)=(nCx).p^{x}.(1-p)^{n-x}

Where ''n'' is the number of Bernoulli experiments (In this case n = 2 because we randomly selected two voters)

P(X=x) is the probability of the variable X to assumes the value x

(nCx) is the combinatorial number define as

(nCx)=\frac{n!}{x!(n-x)!}

p = 0.39 in this exercise.

We are looking for P(X=2) ⇒

P(X=2)=(2C2).(0.39)^{2}.(1-0.39)^{2-2}=(0.39)^{2}=0.1521

If we round to the nearest thousandth the probability is 0.152

What is the sine ratio of angle E? A - 5/3 B - 3/5 C - 5/4 D - 4/5

Answer:

The correct option is B.

Step-by-step explanation:

In a right angled triangle

\sin \theta=\frac{perpendicular}{hypotenuse}=\frac{opposite}{hypotenuse}

In the given triangle DEF, the opposite sides of angle E is DF=6 units and hypotenuse EF=10 units.

The sine ratio of angle E is

\sin E=\frac{DF}{EF}

\sin E=\frac{6}{10}

\sin E=\frac{3}{5}

The sine ratio of angle E is 3/5, therefore the correct option is B.

Find the volume V or height H of the cylinder. Round your answer to the nearest tenth

X = multiplication
h = height
r^2 = radius squared

Formula of a cylinder: Pi x r^2 x height

So, if 176 = 3.14... times 4^2  times h
Then, 176 = 3.14 times 16h 
Next, 176 = 50.24h
Finally, 3.5 = h

You can then check your work by plugging 3.5 back in for the missing height and round to the nearest tenth. :) The answer should come out the same if done correctly.

shoe salesman earns a commission of 30% of all shoe sales made. Yesterday he sold 3 pairs of shoes for $70 each and 2 pairs of shoes for $80 each. How much did he earn in commission yesterday? A. $111 B. $30 C. $42 D. $32

Answer:

$111 is earn by shoe salesman as commission .

Option (A) is correct .

Step-by-step explanation:

As given the statement in the question be as follow.

Shoes salesman sold 3 pairs of shoes for $70 each and 2 pairs of shoes for $80 each.

Thus

Total cost of the pair of shoes = 3 × 70 + 2 × 80

                                                  = 210 + 160

                                                  = $ 370

As given

shoe salesman earns a commission of 30% of all shoe sales made.

30% is written is decimal form

= \frac{30}{100}

= 0.30

Commission earns = 0.30 × Total cost of the pair of shoes .

                               = 0.30 × 370

                               = $ 111

Therefore $111 is earn by shoe salesman as commission .

Option (A) is correct .

What is the y intercept of the line passing through the point (5,-6) with the slope of -1/7

Answer:

The equation of the line would be y = -1/7x - 37/7

Step-by-step explanation:

In order to find this, we need to start with point-slope form.

y - y1 = m(x - x1)

Now we can input the slope in for m and the point in for (x1, y1)

y + 6 = -1/7(x - 5)

y + 6 = -1/7x + 5/7

y = -1/7x - 37/7

How many multiples of 5 are there between 199 and 1,198? Hint: an = a1 + d(n − 1), where a1 is the first term and d is the common difference.

An=a1+d (n-1)
A1=200 since that's the first term that can be a multiple of 5
N=? That's what we need to find
An=1195 since that's the last multiple of 5 that we can use
D=5
Plug in
1195=200+5 (n-1)
-200 both sides
995=5 (n-1)
Distribute 5 to n-1
995=5n-5
+5 both sides
1000=5n
÷5 both sides
N=200 there are 200 multiples of 5 in between 199 and 1198
