Answer:

110in2

Step-by-step explanation:

Area = (base1 + base2 ) * height /2

        = ( 9 + 13) *10 /2 = 110in2

Answers:

110in^2

Step-by-step explanation:

area pf rectangle=l×w

=9in×10in

=90in^2

area of 1st triangle

A=bh/2

=2in×10in/2

=20in^2/2

=10in^2

area of 2nd triangle=10in^2

Area of trapezoid =90in^2+10in^2+10in^2

=11in^2

We have been given a circle H, in which length of arc XY is 78 miles and measure of arc XY is 70 degrees. We are asked to find the radius of circle.

We will use arc length formula to solve our given problem.

[tex]\text{Arc length}=2\pi r\cdot \frac{\theta}{360^{\circ}}[/tex], where,

r = Radius of circle,

[tex]\theta[/tex] = Central angle corresponding to arc.

We know that the measure of central angle that corresponds to arc XY will be equal to measure of arc XY.

[tex]78=2\cdot 3.14\cdot r\cdot \frac{70^{\circ}}{360^{\circ}}[/tex]

[tex]78=2\cdot 3.14\cdot r\cdot \frac{7}{36}[/tex]

[tex]78= 3.14\cdot r\cdot \frac{7}{18}[/tex]

[tex]78= r\cdot \frac{21.98}{18}[/tex]

[tex]r\cdot \frac{21.98}{18}=78[/tex]

[tex]r\cdot \frac{21.98}{18}\cdot \frac{18}{21.98}=78\cdot \frac{18}{21.98}[/tex]

[tex]r=63.8762511373[/tex]

Upon rounding to nearest hundredth, we will get:

[tex]r\approx 63.88[/tex]

Therefore, the radius of circle H is approximately 63.88 miles.

Answer:

C. 17

Step-by-step explanation:

The mean weight can be calculated by adding the numbers 15 + 16 + 15 + 13 + 19 + 20 + 21 divided by the number 7, which is the amount of numbers you just added.

(15 + 16 + 15 + 13 + 19 + 20 + 21)/7

the outcome = 17 which corresponds to answer C.

Answer: The answer is C.17

Step-by-step explanation:

Answer:

y=45

x=90

Step-by-step explanation:

x is a right angle, y is vertical from 45 degrees making it congruent to it.

Answer:

C: x=90 y=45

Step-by-step explanation:

The place where x is is obviously a right angle therefore, it is 90. Then here is a diagonal line cutting through the 90 degrees in half. 90/2=45.

Answer: D : interquartile range

Step-by-step explanation: I just took the test

The measure of variability which should be used in this case interquartile range. so option D is correct.

A quartile is a type of quantile that divides a data set into four equal parts, or quarters. The first quartile (Q1) marks the 25th percentile of the data, the second quartile (Q2) marks the 50th percentile, or median, of the data, and the third quartile (Q3) marks the 75th percentile of the data. These quartiles divide the data into four equal parts and provide information about the distribution of the data and its spread. The interquartile range (IQR), which is the difference between Q3 and Q1, is a measure of the spread of the middle 50% of the data.

When the data is skewed, the mean can be misleading as it is affected by the skewness of the data. In such cases, the median is a better measure of central tendency that represents the typical value of the data.

Therefore, the measure of variability that should be used to describe the data in this case is the interquartile range (IQR). IQR is a measure of spread that is not affected by extreme values or outliers and is often used with skewed data. It is calculated as the difference between the third quartile (Q3) and the first quartile (Q1) of the data.

So, the answer is the interquartile range.

Answer:

-32

Step-by-step explanation:

Look at the attachment

Functions can be represented as equations and graphs.

The value of [tex]\mathbf{-8\cdot f(0)+4\cdot g(-8)}[/tex] is -32

From the graph, we have the following values.

[tex]\mathbf{f(0)= 1}[/tex]

[tex]\mathbf{g(-8)= -6}[/tex]

So, we have:

[tex]\mathbf{-8\cdot f(0)+4\cdot g(-8)= -8 \times 1 + 4 \times -6}[/tex]

Simplify

[tex]\mathbf{-8\cdot f(0)+4\cdot g(-8)= -8 -24 }[/tex]

[tex]\mathbf{-8\cdot f(0)+4\cdot g(-8)= -32 }[/tex]

Hence, the value of [tex]\mathbf{-8\cdot f(0)+4\cdot g(-8)}[/tex] is -32

Answer:

1 / 1296

Step-by-step explanation:

Rolling a 1 for one of the cubes is 1 / 6

1 / 6 * 1 / 6 * 1 / 6 * 1 / 6 = 1 / 1296

Answer:

1 / 1296

Step-by-step explanation:

We have been given that three cubes are being rolled and we are required to find the probability of getting 4 on 1 cubes.

We know the probability of rolling a 4 on one cube will be .  the probability of rolling 4 in each of the individual cubes will be .

But we want 4 to be rolled on 1 cubes at once, in order for that to happen, we need to get a four on first cube AND second cube AND third cube. Since there is AND between the events, we will multiplied their probabilities as per counting principle. Thus, the required probability of rolling 4 on each of the 1 cube is  which simplifies to . 1 / 1296

Answer: -5

Step-by-step explanation:

For each question Sandra answered incorrectly her overall score was changed by -1 point.

Her overall score was -4 before she attempted her last question incorrectly. Since a wrong answer gives her -1 point and her overall is -4

We add her overall and her point from last question which sums up to -5.

So sandras final score is -5

Answer:

Step-by-step explanation:

Rule for the transformations has been given as,

[tex]T_{(5, -0.05)o\text{R}(0, 180)}(x,y)[/tex] defines the rules as the translation by 5 units right and 0.5 units down followed by rotation of the triangle by 180° about the origin.

In other words,

Rule for translation:

F(x, y) → F"(x + 5, y - 0.5)

Followed by the rotation of 180° about the origin,

Rule of rotation,

F"(x', y') → F'(-x, -y)

Following these rules coordinates of the new triangle F'G'H' can be obtained.
