3) 77
4) 37
5) 53

Step-by-step explanation:

Answer:

77°

103°

77°

37°

Step-by-step explanation:

The outer quadrilateral in black is a rectangle because of the angles it has at the vertices.

Look at the upper green line. It intersects the vertical sides of the outer rectangle.

The upper green line intersects the left vertical segment of the outer rectangle at a 103° angle. That makes the top yellow box 77°.

The top yellow box is an angle of a quadrilateral.

360 - 77 - 66 - 114 = 103

The second yellow box is 103°.

The third yellow box is 77°.

The bottom yellow box is 180 - 66 - 77 = 37°

The probability of 20% or more of the sample owning Harleys is 0.95. It is likely that your sample will contain 20% or more who own Harleys.

1. First, calculate the mean number of Harley owners in your sample using the 14% rate of Harley ownership among all motorcycle owners in the US:

2. Next, calculate the standard deviation of the number of Harley owners in your sample using the 14% rate of Harley ownership:

3. Calculate the number of standard deviations that 20% (100 Harley owners) is from the mean of 70 Harley owners:

4. Using a standard normal distribution table, we find that the probability of obtaining 1.79 standard deviations or more from the mean is about 0.9643. Therefore, it is likely that your sample will contain 20% or more who own Harleys.

The graph with the dilated line segment is given by the image shown at the end of the answer.

A dilation happens when the coordinates of the vertices of an image are multiplied by the scale factor, changing the side lengths of a figure, thus a dilation is classified as a non-rigid transformation.

The endpoints of the line segment in this problem are given as follows:

(0,0) and (5,5).

The scale factor of the dilation is given as follows:

k = 2.

Then the endpoints of the dilated line segment will be obtained multiplying each of the coordinates of each of the endpoints by the scale factor of 2, as follows:

(0,0) and (10,10).

The number of miles Joseph traveled in one hour is calculated to be 20.25 miles

Since Joseph drove 27 miles in 1 1/3 hours, we first convert 1 1/3 into simpler form as follows;

1 1/3 hours = 4/3 hours

Now we can determine how far he traveled in one hour if he drove at a constant rate by cross multiplication as follows;

4/3 hours = 27 miles

1 hour = x

Here x represents the number of miles traveled in one hour;

1 × 27 = 4/3x

27 = 4/3x

x = 27/(4/3)

x = 27 × 3/4

x = 20.25 miles

Hence Joseph travels 20.25 miles in one hour.

Answer: the area of the triangle is (1/2) * √20 cm

Step-by-step explanation:

The area of a triangle is equal to one half of the product of the base and the height. In this case, the base of the triangle is √20 cm and the height is √8 cm, so we can find the area by doing this:

Area = (1/2) * (√20 cm) * (√8 cm)

To simplify this expression, we can first multiply the numerator and denominator by the square root of the denominator:

Area = (1/2) * (√20 cm * √8 cm) / (√8 cm)

This gives us:

Area = (1/2) * (√160 cm^2) / (√8 cm)

Now we can cancel out the square root of 8 in the numerator and denominator:

Area = (1/2) * √160 cm^2 / √8 cm

Area = (1/2) * √20 cm

Thus, the area of the triangle is (1/2) * √20 cm, which is the simplified radical form of the answer.

Step-by-step explanation:

Given problem,

→ (3x² + 8x - 7) - (5x² + 2x - 11)

Let's solve the problem,

→ (3x² + 8x - 7) - (5x² + 2x - 11)

→ 3x² + 8x - 7 - 5x² - 2x + 11

→ (3x² - 5x²) + (8x - 2x) + (-7 + 11)

→ (3 - 5)x² + (8 - 2)x + 4

→ -2x² + 6x + 4

Hence, answer is -2x² + 6x + 4.

The slower pipe if working alone can fill the tank in 10.5 hours.

A cuboid is a three-dimensional solid that has 6 faces (rectangular), 8 vertices, and 12 edges. A cuboid has three dimensions such as length, width, and height. A perfect cuboid is said to be a cuboid that has integer edges and the formula for its volume is: V = length ×breadth× width

Given here dimensions of the swimming pool as 30 feet long, 14 feet wide, and an average depth of 8 feet, therefore the volume of the swimming pool V = 30×14×8

  = 3360 feet³

Again the two pipes working together can fill the pool in 3.5 hours and let their speeds 2x and x then, their relative speed = 3x

thus we have 3.5 = 3360/3x

                  ⇒   x  = 320 feet³/hr

Therefore the individual speeds are equal to 320 feet³/hr and 640 feet³/hr

Accordingly, the time taken by the slower pipe to fill the entire tank alone is = 3360/320

             = 10.5 hours

Hence, the time taken by the slower pipe is 10.5 hours

Option 2 is correct that is 1.79

When presented in ascending order, the value that 75% of data points fall within is known as the higher quartile, or third quartile (Q3).

The quartiles formula is as follows:

Upper Quartile (Q3) = 3/4(N+1)

Lower Quartile (Q1) = (N+1) * 1/3

Middle Quartile (Q2) = (N+1) * 2/3

Interquartile Range = Q3 -Q1,

1.74, 0.24, 1.56, 2.79, 0.89, 1.16, 0.20, and 1.84 are available.

Sort the data as follows: 0.20, 0.24, 0.89, 1.16, 1.56, 1.74, 1.84, 2.79 in ascending order of magnitude.

The data set has 8 values.

hence, n = 8; third quartile: 3/4 (n+1)th term

Q3 =3/4 of a term (9) term

Q3 =27/4 th term

Q3 = 1.74 + 1.84 / 2 (average of the sixth and seventh terms)

equals 1.76

Thus Q3 is 1.76 that is option 2

The length of p is 411 cm.

Every three-sided polygon having three edges and three vertices is referred to as a triangle in geometry. The most important attribute of a triangle is that its internal angles sum to 180 degrees. The triangle's angle sum attribute is what is known as.

As per the given data:

We are given a triangle, and we know 2 angles of the triangle and one side.

In ΔPQR:

r = 38 cm

∠P = 49°

∠Q = 127°

From the angle sum property for a triangle:

∠P + ∠Q + ∠R = 180°

49° + 127° + ∠R = 180°

∠R = 180° - 176°

∠R = 4°

By using the sine rule in a triangle:

sin(∠P)/p = sin(∠R)/r

p = [sin(∠P)/sin(∠R)] × r

p = [sin(49°)/sin(4°)] × 38

p = 411 cm

The length of p is 411 cm.

Correct formatting for a nested function is

=IF(AND(B2>3000,02>2000),"Bonus","No Bonus")

A nested If statement is used when 1 or more conditions are to be tested. The result of the nested function depends based on the true value of the function.

i.e. If the nested statement is true, certain operations are to be done otherwise, do something else. In other words, the IF function allows you to make a logical comparison between a value and what you expect by testing for a condition and returning a result if True or False.

The syntax of a nested function goes thus

IF( condition1, value_if_true1, IF( condition2, value_if_true2, value_if_false2 ))

This would be equivalent to the following in Excel

The area of the shaded region in the rectangle is given as follows:

42 units squared.

The area of a rectangle of base b and height h is given by the multiplication of these dimensions, as follows:

Area = base x height.

For the shaded region in this problem, given by the image shown at the end of the answer, the area can be obtained as the subtraction of the area of the entire rectangle by the area of the non-shaded region.

The entire rectangle has base 11 and height 12, hence it's area is given as follows:

Ar = 11 x 12 = 132 units².

The non-shaded region has base of 9 units and height of 10 units, hence it's area is given as follows:

An = 9 x 10 = 90 units².

Then the area of the shaded region on the rectangle is calculated as follows:

As = Ar - An = 132 - 90 = 42 units².

If the sales tax is 6. 35% then Claire's total is $15.63

In this questiion we have been given Claire buys a pair of earrings for $4, a necklace for $10, and a ring for $7.

So, her total purchase is:

4 + 10 + 7 = 21 dollars

She has a 30% off coupon for her whole transaction.

We find the 30 percent of 21

(30/100) * 21 = 6.3 dollars

So, she will get discount of 6.3 dollars.

So, the amount would be,

21 - 6.3 = $14.7

The sales tax is 6. 35%

Now we find 6.35 percent of 14.7

6.35% of 14.7

= 0.0635 × 14.7
