The square has sides of 12 in and the area of a square is side × side. The area of the shaded region exists 144 sq. in.

The area of a square can be estimated by squaring the number describing the measure of the side of the square.

The area of a shape exists as the number of unit squares needed to completely cover it. Therefore, it exists calculated and expressed in square units.

The area of a square exists equivalent to (side) × (side) square units. The area of a square when the diagonal, d, exists given exists d²÷2 square units.

The square has sides of 12 in and the area of a square is side × side. Therefore, the area exists 12² which is 144 sq. in.

The upper and lower bounds of each of the numbers are;

1a) Upper bound of 6 = 6.5

Lower bound of 6 = 5.5

b) Upper bound of 83 = 83.5

Lower bound of 83 = 82.5

c) Upper bound of 152 = 152.5

Lower bound of 152 = 151.5

The range as intervals of inequality are;

i) 5.5 ≤ x ≤ 6.5

ii) 82.5 ≤ x ≤ 83.5

iii) 151.5 ≤ x ≤ 152.5

The procedure to identify the upper and lower bounds is;

1) Identify the place value of the degree of accuracy stated.

2) Divide this place value by 2.

3) Add this amount to the given value to find the upper bound, subtract this amount from the given value to find the lower bound.

ai) Since it was approximated to the nearest whole number, then we say that the place value of the degree of accuracy is 1.

Divide by 2 to get; 1/2 = 0.5

Upper bound of 6 = 6 + 0.5 = 6.5

Lower bound of 6 = 6 - 0.5 = 5.5

ii) Since it was approximated to the nearest whole number, then we say that the place value of the degree of accuracy is 1.

Divide by 2 to get; 1/2 = 0.5

Upper bound of 83 = 83 + 0.5 = 83.5

Lower bound of 83 = 83 - 0.5 = 82.5

iii) Since it was approximated to the nearest whole number, then we say that the place value of the degree of accuracy is 1.

Divide by 2 to get; 1/2 = 0.5

Upper bound of 152 = 152 + 0.5 = 152.5

Lower bound of 152 = 152 - 0.5 = 151.5

bi) The range as an inequality is;

5.5 ≤ x ≤ 6.5

ii) The range as an inequality is;

82.5 ≤ x ≤ 83.5

iii) The range as an inequality is;

151.5 ≤ x ≤ 152.5

The answer is option(1) i.e, f(n) = 3n-1, This question is of Arithmetic Sequence

Arithmetic Sequence the difference between one term and the next is a constant. Formula is,

aₙ = a + (n-1)d

aₙ = the nᵗʰ term in the sequence

a = the first term in the sequence

d = the common difference between terms

According to question the sequence is,

2 inches, 5 inches, 8 inches .....

where, a = 2

            d = 5 - 2 = 3

Now, put these value in formula i.e, aₙ = a + (n-1)d

aₙ = 2 + (n - 1) * 3

    = 2 + 3n - 3

     = 3n - 1

Equation of the new perpendicular line is  [tex]y - y_{1} = -\frac{1}{4} (x- x_1)[/tex]

How to calculate the new perpendicular line?

The given equation is:

y- 8=4 (x-5)​

This equation is of the point- slope form

[tex]y- y_{1}= m(x-x_{1})[/tex]

y - 8 = 4( x-5 )​

So, the slope (m) is m = 4

The points [tex](x_1,y_1) = (5,8)[/tex]

Hence, slope of the line perpendicular to the given line is

m = [tex]-\frac{1}{4}[/tex]

The equation of the new perpendicular line is :

The scale factor, if MJ is 25 ft. long and M'J' is 5 feet long is 1/5

If MJ is considered as the original figure, it is 25 ft. long.

The image of MJ, M'J' is 5 feet long

Scale factor is generally understood as the number of times the dimensions of the image is enlarged or diminished

Scale factor = Dimension of the new image ÷ Dimension of the original shape

Scale factor = M'J' length/ MJ length

k = 5/25

k = 1/5

The value of scale factor = 1/5, which means the new image is diminished.

Therefore the scale factor, if MJ is 25 ft. long and M'J' is 5 feet long is 1/5.

Answer:  45

Step-by-step explanation:

The new variance for the data is 0.35 .

In statistics and probability theory, variance is the predicted squared deviation of a stochastic process from its mean or actual values.

Dispersion, or how far apart from the mean a set of data are from one another, is measured by variance.

A few ideas that involve variance are descriptive statistics, parameter estimation, testing hypotheses, quality of fit, and Monte Carlo sampling.

Variance is a vital tool in the fields where statistical data analysis is widely used.

The standard deviation squared is a measure of the variance, which is also referred to as the second systematic of a distribution and the correlation between the random variable and itself.

We know that variance = (standard deviation)²

When the value of the data increases by 25 cents a box , then the standard deviation will remain the same as the mean will only increase and the change in mean has no effect on the SD.

Hence the variance will effectively remain the same.

therefore the new variance is 0.35

The polar bear has a birth weight of 0.5 kilogram.

The linear equation is y = x + 0.4t

Given,

The weight gained by polar bear each week after it was born = 0.4 kg

The weight of polar bear after 3 weeks = 1.7 kilo grams

We have to write an linear equation to represent this ;

Here,

y be the weight of polar bear

x be the initial weight

t be the number of week.

So,

the equation be like;

y = x + 0.4t

Then,

1.7 = x + 0.4 x 3

x = 1.7 - 1.2 = 0.5

The surface area is increasing at the rate of (60 x + 150) cm² per second.

Let the side of the cube be x cm.

s = x cm

Surface area of the cube will be:

S = 6 x² cm²

Now, we are given that, the side of the cube is expanding 5 cm per second.

So, the side of the cube after 1 second will be:

s' = x + 5 cm

Surface area will be:

S' = 6 (x + 5)² cm²

S' = (6x² + 150 + 60 x) cm²

Change in the surface area is:

ΔS = (6x² + 150 + 60 x) cm² - 6 x² cm²

ΔS = (60 x + 150) cm²

Therefore, the surface area is increasing at the rate of (60 x + 150) cm² per second.

Answer:

for calculator steps

Step-by-step explanation:

-Find out what 1% of the whole amount (B) is - to do this you divide it by 100.

-Once you know the value of 1% you can multiply this amount by the number of percent you want to find.

-If you want to find 10% of 50 you divide 50 by 100.

-From this you know that 1% of 50 is 0.5

-So to find 10% you just multiply 0.5 by 10

-0.5 x 10 = 5

-10% of 50 = 5

The total chnage in the stock market from the day beginning of the day to the end of the day is -89 3/4 points.

A stock market simply means the market where shares and stocks are sold.

In the information illustrated, at beginning of the day the stock market goes up 30 1/2 points and at the end of the day the stock market goes down 120 1/4 points.

The change will be the the operation of the numbers through the use of addition when it goes up and subtraction when it comes down. This will be:

= 30 1/2 - 120 1/4

= -89 3/4

3y - 8x = -46

substitute the value of y

3(8 - 6/5x) - 8x = -46

solve the equation

x = 175 / 29

substitute the value of x

y = 8 - 6/5(175/29)

solve the equation

y = 22/29
