investment A save £160 per month for 2 years. 2.5% interest is added to the total amount saved. Investment B invest £3800. Compound interest is added at 3% each year

Answers

Answer:

95.42

Step-by-step explanation:

Investment A:

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.

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

Given:

The universal set is

U = {c, d, e, f, g, h, i}

The other set is

A = {c, e, h, i}

To find:

The set A'

Solution:

We know that,

Complement of a set A = Universal set - set A

A' = U - A

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

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:

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%

Answer: 1859.5 mini bears

Step-by-step explanation:

From the information given in the question,

10 mini bars = 12.1 grams

10 regular bars = 23.1 gram

1 super bear = 2250 grams

To eat enough mini bears to match the super bears, the number that it'll take will be:

Since 10 mini bars = 12.1 grams

1 mini bear = 12.1 grams / 10 = 1.21 gram

Since 1 super bear = 2250 grams, the number of mini bears needed to equate this will be:

= 2250/1.21

= 1859.5 mini bears
