The value of M and N from the given expression is -10 and -21 respectively

Sum of functions is the addition of expression. Given the expression below;

M = 5(x + 1) and;

N = (6x - 3)

Take the difference of the expressions

M - N = 10

Substitute

5(x+1) - (6x-2) = 10

Expand the expression to have:

5x + 5 -6x + 2 = 10
5x - 6x + 5 + 2 = 10
-x + 7 = 10
-x = 10 - 7
-x = 3
x = -3

Determine the value of M

M = 5x + 5
M = 5(-3) + 5
M = -15 + 5
M = -10

Determine the value of N

N = 6x - 3
N = 6(-3) - 3
N = -18 - 3
N = -21

Hence the value of M and N from the given expression is -10 and -21 respectively

Answer:

a=120

b=60

Step-by-step explanation:

a and 60 are supplementary angles, meaning they add up to 180 degrees.

To find a, subtract 60 from 180 = 120 degrees.

All of the angles within the quadrilateral add up t0 360. Since there are two right angles within, those add to 180. Subtract 180 and 120 from 360 = 60 degrees.

Answer:

37.7 inches

Step-by-step explanation:

She wants to paint the line along the circumference of the plate.

The plate is circular; the circumference of a circle is given as:

C = πD

where D = diameter

The diameter of the plate is 12 inches, therefore:

C = π * 12 = 37.7 inches

The line will be 37.7 inches long.

The area of the floor in the scale drawing will be equal to 150 in².

An object's area is how much space it takes up in two dimensions. It is the measurement of the number of unit squares that completely encompass the surface of a compact figure. The squared unit, which is frequently expressed as inches, square feet, etc., is the accepted unit of area.

As per the given information in the question,

Length of the classroom, l = 30 feet and,

The width of the classroom, w = 20 feet.

As per the scale drawing, the length of the classroom, l' = 15 feet

Let the scale width, w' = x feet

As we can see that the original length is twice the scale drawing.

Then, the original width also is twice the scale drawing.

So, w' = 20/2 = 10 feet.

Now, the area of the floor in the scale drawing will be,

Answer:

534.37500

Step-by-step explanation:

1/42.75 = 12.5/x

x= 534.37500

you setup a ratio of litre/cost = litre/cost

you can also multiply 42.75 by 12.5, which is way easier.

a) 95% confidence interval of the true mean : 88.98 < µ < 103.02

b) 95% confidence interval of the mean heart rate : 93.91 < µ < 98.09

Given ,

Point estimate = sample mean = X  = 96

Sample standard deviation = s = 15

Sample size = n = 20

= n - 1 = 20 - 1 = 19

Here,

Using t-distribution because standard deviation unknown

At 95% confidence level the t is,

\(t_{\alpha /2\), df  = t0.025,19 = 2.093

At 95% confidence level the t is,

α = 1 - 95%

= 1 - 0.95

= 0.05

α / 2 = 0.05 / 2

= 0.025

\(t_{\alpha /2\), df

 = \(t_{0.025,19\)

= 2.093

Margin of error,

E = \(t_{\alpha /2\) , df * s/√n

= 2.093 * 15/√20

= 7.02

Margin of error = E = 7.02

The 95% confidence interval estimate of the population mean is,

X - E < µ < X + E

96 - 7.02 < µ < 96 + 7.02

88.98 < µ < 103.02

b)

n = 200

degrees of freedom = n - 1 = 200 - 1 = 199

At 95% confidence level the t is,

\(t_{\alpha /2\), df  = \(t_{0.025,199\)

= 1.972

Margin of error,

E = \(t_{\alpha /2\) , df * s/√n

E = 1.972 * 15/√200

E = 2.09

The 95% confidence interval estimate of the population mean is,

X - E < µ < X + E

Answer:

Step-by-step explanation:

Square Root of 225 is 15 (with -15 also it would work but let’s stick to positive root)

Now, the 1st Odd Number is 15 -2 = 13 and the 3rd Odd Number is 15 + 2 = 17.

The required Numbers are 13 and 17.

This works for 3 consecutive Even Numbers also.

Why does it work?

Because, if we have 3 numbers to be a-2, a and a+2 (Doesn’t really matter if a is positive or negative)

(a-2)*(a+2) = a^2 - 4

So, you see adding 4 to the Product of the 1st Number and the 3rd Number (a^2 - 4 + 4 = a^2) gives you the square of the Middle Number, which is a^2!

Out of the 1300 cargo containers, approximately 30 containers (2.28% of 1300) are expected to weigh more than the mean by 2 standard deviations.

If the distribution of weights of a sample of 1300 cargo containers is symmetric and bell-shaped, we can assume that it follows a normal distribution. In a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, and approximately 95% of the data falls within two standard deviations of the mean.

Therefore, if we want to know what percent of the data is above the mean by 2 standard deviations, we need to calculate the area under the normal distribution curve to the right of the mean plus 2 standard deviations. This is equivalent to finding the area in the upper tail of the distribution.

Using a standard normal table or a calculator, we can find that the area to the right of mean plus 2 standard deviations in a standard normal distribution is approximately 2.28%. Since the given distribution is assumed to be a normal distribution, we can conclude that approximately 2.28% of the cargo containers weigh more than the mean by 2 standard deviations.

Therefore, out of the 1300 cargo containers, approximately 30 containers (2.28% of 1300) are expected to weigh more than the mean by 2 standard deviations.
