A 4-column table with 3 rows. The first column has no label with entries 9th graders, 10th graders, total. The second column is

labeled has a sibling with entries 64, 52, 116. The third column is labeled does not have a sibling with entries 17, 23, 40. The fourth column is labeled total with entries 81, 75, 156.
Which statements are correct about the two-way frequency table? Check all that apply.

The survey represents quantitative data.
There is a greater percentage of 10th graders who do not have a sibling than 9th graders who do not have a sibling.
The total number of students in the poll who have a sibling is 116.
Fifty-two 10th graders were polled.
More 9th graders were polled than 10th graders.

Awsner this with step by step (can use calculator)​
ss7ja [257]

Answer:

x = 9.2

x =22.0

x = 8.7

Step-by-step explanation:

Required

Find x

(a)

x is calculated using tangent formula

\tan(57) = \frac{x}{6}

Make x the subject

x = 6 * \tan(57)

x = 6 * 1.5399

x = 9.2394

x = 9.2 --- approximated

(b):

x is calculated using cosine formula

\cos(60) = \frac{11}{x}

Make x the subject

x = \frac{11}{\cos(60)}

x = \frac{11}{0.5}

x =22.0

(c):

x is calculated using sine formula

\sin(60) = \frac{x}{10}

Make x the subject

x = 10 * \sin(60)

x = 10 * 0.8660

x = 8.660

x = 8.7 --- approximated

Write the equation of the lines resented below in slope-intercept form
scoray [572]

Slope intercept form: y = mx + b

mx = slope

b = y-intercept

We know the y intercept is 0, so nothing will be written there.

To find the slope of this line, we can use the slope formula.

\frac{y.2 - y.1}{x.2 - x.1} = m

We'll use the points (1, 0) and (3, 1) to find the slope.

Now we can just plug these values into the equation to find the slope.

1 - 0 / 3 - 1

1 / 2

The slope of the line is 1/2, or 0.5.

The slope-intercept form of this line can be written as:

y = 0.5x

What is the value of y?<br><br><br><br> Enter your answer in the box.<br><br> y =
Olenka [21]

Answer:

y=40\°

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal angles

The two equal angles are called the base angles and the third angle is called the vertex angle

In this problem the triangle ABC is an isosceles  triangle

so

AB=AC

5x=40\°

x=8\°

The sum of the internal angles of a triangle is equal to 180\°

so

Find the value of y

(2y+20)\°+2(40\°)=180\°

2y=180\°-20\°-80\°

2y=80\°

y=40\°

HELP PLEASE ILL TRY TO MARK U BRAINLIEST
Anon25 [30]

Step-by-step explanation and answer:

For this you just need to plug in x for y = f(1/5x)

1/5(-4) = -4/5 or -0.8

1/5(-1) = -1/5 or -0.2

1/5(0) = 0

1/5(3) = 3/5 or 0.6

1/5(6) = 6/5 or 1.2 or 1 1/5
