a rectangle is drawn so the width is 49 inches longer than the height. if the rectangle's diagonal measurement is 61 inches, find the height.

"95% confidence interval" means that there is a 95% chance that the true fraction falls within the computed confidence interval.

Confidence Intervals: Confidence intervals are the range of estimates for unknown parameters.

Confidence intervals are more than just a range of estimated values. It also tells you how stable the estimates are. A stable estimate is an estimate that has approximately the same value if the study is repeated. An unstable estimate is one that would vary from one sample to another.

The confidence interval determines the range that one can be certain that contains the true mean of the population.

This means that, The 95% confidence means, there is a 95% chance that the true proportion will be in the calculated confidence interval or 95 percent confidence interval, you have a 5 percent chance of being wrong.

Hence, the true statement that represents "95% confidence interval" is chance of true fraction of sucess.

(a) not picking a square  ,

(d) picking shape that has only straight edges ,

(e) not picking a circle   .

In the question ,

it is given that ,

there are 2 circles , 4 triangles , 2 squares .

(a) probability of not picking a square = ( circles + triangles )/total

Answer:

Step-by-step explanation:

first of all the graph is shifted up by 1 then we should add 1 to the function we have.

after that its obvious that the function is sine because if we remove the 1 we add it then it will be 0 when the angle is 0.

the function we have now is y = 1 + sin(ax).

to know the value of a we choose an angle we already know its sine for example:

2 = 1 + sin(a * 1/8)

1 = sin(a * 1/8)

sin-1(1) = PI/2 = a*1/8 => PI = 180

a = 4 * PI

at the end we will have => y = 1 + sin(4PI * x).

the perimeter of the composite figure is 20cm and its area is 37cm².

what is perimeter  ?

Perimeter is the total length of the boundary of a two-dimensional shape or figure. In other words, it is the distance around the outside of a shape. To find the perimeter of a shape, you simply add up the lengths of all its sides.

In the given question,

To find the perimeter of the composite figure, we need to add up the lengths of all the sides.

Starting from the left side of the figure, we have a vertical line segment of length 6cm, followed by a horizontal line segment of length 5cm, then another vertical line segment of length 2cm, followed by a slanted line segment of length 3cm, then another horizontal line segment of length 2cm, and finally, a vertical line segment of length 2cm.

So the perimeter of the composite figure is:

Perimeter = 6cm + 5cm + 2cm + 3cm + 2cm + 2cm

Perimeter = 20cm

To find the area of the composite figure, we can break it down into simpler shapes and add up their areas.

The composite figure can be split into two rectangles, one with dimensions 6cm x 5cm and the other with dimensions 2cm x 2cm, and a right triangle with base 3cm and height 2cm.

The area of the first rectangle is:

Area = length x width

Area = 6cm x 5cm

Area = 30cm²

The area of the second rectangle is:

Area = length x width

Area = 2cm x 2cm

Area = 4cm²

The area of the right triangle is:

Area = (base x height) / 2

Area = (3cm x 2cm) / 2

Area = 3cm²

Therefore, the total area of the composite figure is:

Area = 30cm² + 4cm² + 3cm²

Area = 37cm²

So the perimeter of the composite figure is 20cm and its area is 37cm².

Answer:

1) b = 17/4

2) x = -3/5

Step-by-step explanation (question one):

Step 1: Simplify both sides of the equation.

3b +9 + −5b + 3 = −14 +6b +−8

(3b +−5b) +(9 +3)=(6b) +(−14 + −8) (Combine Like Terms)

−2b +12 = 6b −22

Step 2: Subtract 6b from both sides.

−2b +12 −6b = 6b −22 −6b

−8b +12 = −22

Step 3: Subtract 12 from both sides.

−8b +12 −12 = −22 −12

−8b = −34

Step 4: Divide both sides by -8.

(-8b/-8) = (-34/-8)

Step 5: Get your Answer

b = 17/4

Step-by-step explanation (question two):

Step 1: Simplify both sides of the equation.

2x +5 + −4x +8 = (5)(5) +(5)(6x) + −12x (Distribute)

2x +5 + −4x +8 = 25 +30x + −12x

(2x+−4x) + (5+8) = (30x +−12x) +(25) (Combine Like Terms)

−2x +13 = 18x +25

Step 2: Subtract 18x from both sides.

−2x +13 −18x= 18x +25 −18x

−20x +13 = 25

Step 3: Subtract 13 from both sides.

−20x +13 −13 = 25 −13

−20x=12

Step 4: Divide both sides by -20.

(-20x/-20) = (12/-20)

Answer:

The cost of 6 cans of soup is 3.75

Step-by-step explanation:

1 can = x

12x = 7.50

We need to find the cost of 1 can. So we divide 7.50 by 12.

x = 0.625

Then multiply by 6.

0.625 x 6 = 3.75

As a result the cost of 6 cans of sup is $3.75

Answer:

C. five samples.

Step-by-step explanation:

By solving a linear equation, we will see that the value of the greater integer is 12.

Let's define x as the smaller integer, then the greater integer is:

x + 2

(is +2 because is the next consecutive even integer)

We know the sum of an integer and 4 times the next consecutive even integer is 58.

So we can write the linear equation:

x + 4*(x + 2) = 58

x + 4x + 8 = 58

5x = 58 - 8

5x = 50

x = 50/5

x = 10

Then the greater integer is x + 2 = 10 + 2 = 12

Based on the calculation below, the number of years the person must leave the money in the bank until it reaches 6500 dollars is 4.3 years.

This can be calculated using the formula for calculating the future value (FV) as follows:

FV = PV(1 + r)^n ......................... (1)

Where:

FV = future value or the amount in the bank after certain years = 6500

PV = present value or the amount invested = 5000

r = quarterly interest rate = 6.25% / 4 = 0.0625 / 4 = 0.015625

n = number of quarters

Substituting relevant values into equation (1) and solve for n, we have:

6500 = 5000(1 + 0.015625)^n

6500 / 5000 = 1.015625^n

1.3 = 1.015625^n

Log linearize both sides, we have:

log1.3 = n * log1.015625

0.1139 = n0.0067

n = 0.1139 / 0.0067

n = 17 quarters

Number of years the money must be in the bank = n / number of quarters in a year = 17 / 4 = 4.25 years

To the nearest tenth of a year, we have:

Number of years the money must be in the bank = 4.3 years

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

-3x - 2y <6

Let's consider an equation of a line,

-3x-2y = 6

-2y = 3x + 6

y = -3/2x - 3

So, slope = -3/2

Substitute y =0 in the equation of a line

So, y-intercept at (0,-2)

Due to Inequality, the graphical representation of the line is a dashed line.

Hence, the line is dashed with a y-intercept at (0,-2) and a slope of -3/2

The number of unit cubes it would take to completely fill the prism with no gaps between unit cubes is 72

From the question, we are to determine how many unit cubes it would take to completely fill the prism with no gaps between unit cubes.

To do this, we will calculate the volume of rectangular prism

Assuming each cube is 1 cubic unit

Then,

From the top view,

The length of the rectangular prism = 9 units

The width of the rectangular prism = 2 units

From the Right-side view,

The height of the rectangular prism = 4 units

Thus,

The volume of the rectangular prism = 9 × 2 × 4

Volume of the rectangular prism = 72 cubic units

Now,

Number of cubes required to fill the rectangular prism = Volume of the prism / Volume of the cubes

Number of cubes required to fill the rectangular prims = 72 / 1
