percent of 45.

Answers

Answer:

20%

Step-by-step explanation:

When asked, "x is what percent of y?" divide x by y and multiply by 100.

9/45 = 0.2

0.2 * 100 = 20%

Recall that we multiply by 100 to convert decimal to percent.

Step-by-step explanation:

Let x% of 45 be 9 Then

x % of 45 = 9

x / 100 * 45 = 9

45x = 900

x = 900 / 45

x = 20%

Write an equation of a line that passes through the two given points. Your answer should be written in slope-intercept form.
P(-8,-8),q ( 0,0)

Answers

Answer:

y = x

Step-by-step explanation:

Find the slope using rise over run (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(-8 - 0) / (-8 - 0)

-8 / -8

= 1

So, the slope is 1.

Plug in the slope and a point into y = mx + b and solve for b:

y = mx + b

-8 = 1(-8) + b

-8 = -8 + b

0 = b

Plug in the slope and y intercept into y = mx + b

y = mx + b

y = 1x + 0

y = x

So, the equation of the line is y = x

According to records, the amount of precipitation in a certain city on a November day has a mean of 0.10 inches, with a standard deviation of 0.07 inches. What is the probability that the mean daily precipitation will be 0.11 inches or less for a random sample of November days (taken over many years)?

Carry your intermediate computations to at least four decimal places. Round your answer to at least three decimal places.

Answers

Answer:

The probability that the mean daily precipitation will be 0.11 inches or less for a random sample of November days

P(X≤ 0.11) = 0.4404

Step-by-step explanation:

Step(i):-

Given that the mean of the Population = 0.10 inches

Given that the standard deviation of the population = 0.07inches

Let 'X' be a random variable in a normal distribution

[tex]Z = \frac{x-mean}{S.D} = \frac{0.11-0.10}{0.07} = 0.1428[/tex]

Step(ii):-

The probability that the mean daily precipitation will be 0.11 inches or less for a random sample of November days

P(X≤ 0.11) = P(Z≤0.1428)

               =  1-P(Z≥0.1428)

              =  1 - ( 0.5 +A(0.1428)

            =  0.5 - A(0.1428)

            = 0.5 -0.0596

           = 0.4404

Final answer:-

The probability that the mean daily precipitation will be 0.11 inches or less for a random sample of November days

P(X≤ 0.11) = 0.4404

Answer:

The 4 interior angles in the square are each 90 degrees. The four angles formed by the intersection of the 2 diagonal lines are each 90 degrees. The rest of the angles <PQT, <RQT, etc. Are all 45 degrees.

Answer:

The following angles are 45 degrees: SPT, QPT, PQT, RQT, QRT, SRT, RST, PST.

The following angles are 90 degrees: STP, PTQ, QTR, RTS

Step-by-step explanation:

Notice that it is a square. Since it is a square, any diagonal line drawn from a corner to the opposite corner will bisect the angle at both corners. Since in a square each angle at each corner is 90 degrees, we know that the angles listed above are 45 degrees.

There are multiple ways to arrive at the conclusion that angles STP, PTQ, QTR, RTS are all 90 degrees. The easiest way to arrive at that answer is looking at each triangle. Notice how the square is divided into 4 triangles. Each triangle contains two 45 degree angles. Since the internal angles of each triangle must sum to 180 degrees, this means the last angle is 90 degrees.

What are the steps for solving 6x+2y=4

Answers

Answer:

X=4-2y/6

Y=4-6x/2

Step-by-step explanation:

For X:

1) -2y

Once you subtract 2y you are left with 6x=4-2y

2) Divide by 6 on both sides to get x alone

That would give you your answer of X=4-2y/6

For Y:

1) -6x

After subtracting 6x you would have 2y=4+6x

2) Like the steps above, you divide by 2 on both sides and that would give you your answer of Y=4-6x/2

Step-by-step explanation:

160*24*1.025=3936

Investment B:

3800(1+.03)^2=4031.42

4031.42-3936= 95.42

Investment B is  95.42 more than investment A.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

Given,

investment A save £160 per month for 2 years.

2.5% interest is added to the total amount saved.

Investment A:

160×24×1.025=3936

Investment B:

Investment B invest 3800.

Compound interest is added at 3% each year

Convert 3% to decimal value by dividing 3 by 100.

3/100=0.03

P=A(1+r)t

A is initial deposit, r is rate of interest and t is time

3800(1+0.03)²

3800(1.03)²=3800×1.0609

=4031.42

We need to find how much investment B has more than investment A.

To find this let us find difference between investment A and  investment B.

4031.42-3936= 95.42

Hence investment B is  95.42 more than investment A.
