The table shows the results of a survey at a local school. The survey asked 7th and 8th graders if they pack their lunches or if they buy their lunches in the school cafeteria. Here are the results.

47 seventh graders were surveyed and 19 of them pack their lunches.
52 eighth graders were surveyed and 33 of them buy their lunches.
Construct a two-way frequency table for the data.

Step-by-step explanation:

72/20=3.6

3.6*3=10.8

Answer: exponential

Step-by-step explanation:

its exponential

count the squares in each one

first is 2 squares

second is 4 squares

third is 8 squares

this is going up exponentially because the first one would be 2^1 the second would be 2^2 and the third would be 2^3

Answer:

[tex](-4,-13)[/tex] and [tex](4,3)[/tex] the intersection points.

Step-by-step explanation:

Intersection point of two functions is a common point which satisfies both the functions.

Given functions are,

[tex]f(x)=2x-5[/tex]

[tex]g(x)=x^2+2x-21[/tex]

For a common point of these functions,

[tex]f(x)=g(x)[/tex]

[tex]2x-5=x^2+2x-21[/tex]

[tex]-5=x^2-21[/tex]

[tex]0=x^2-16[/tex]

[tex]x^2=16[/tex]

[tex]x=-4,4[/tex]

For [tex]x=-4[/tex],

[tex]f(-4)=g(-4)=2(-4)-5[/tex]

                       [tex]=-13[/tex]

For [tex]x=4[/tex],

[tex]f(4)=g(4)=2(4)-5[/tex]

                  [tex]=3[/tex]

Therefore, [tex](-4,-13)[/tex] and [tex](4,3)[/tex] the intersection points.

x = 24.35°

Step-by-step explanation:

Recall that

cos²x - sin²x = cos 2x

which means that

cos 2x = 0.66 ---> 2x = cos^-1 (0.66) = 48.7°

or x = 24.35°

Answer:

x = 24.35, 155.65, 204.35, 335.65  degrees ( for 0 < x < 360 degrees).

Step-by-step explanation:

cos²x - sin²x = 0.66

cos^2 x = 1 - sin^2 x so

1 - sin^2 x - sin^2 x = 0.66

1 - 2sin^2 x = 0.66

2sin^2 x = 1 - 0.66

sin^2x = 0.34/2 = 0.17

sin x = +/- √0.17

= +/- 0.41231

x = 24.35 degrees ( in first quadrant)

and 180 + 24.35 = 204.35 degrees in third quadrant.

Answer:

50

Step-by-step explanation:

68+62=130 then subract 180-130 and have 50 so x=50

Answer:

x°=50°

Step-by-step explanation:

Because of the Vertical Angle Theorem, the blank angle across from 68° is the same measure. Therefore, since the blank angle is 68°, then x° would be 50° because 180-62-68=50 due to the Triangle Angle Sum Theorem.

Answer:

0

Step-by-step explanation:

because you have to look at what both sides of the graph is doing as it approaches 2.

from the left, we can see the the graph is going down All the way to 0 at x=2.

and from the right side, the graph is going up to 0 at x=2.

therefore the graph is approaching 0.

The limit of h(x) as x tends to 2 is equal to 0.

Remember that a limit is not the same as an evaluation, the limit studies the behavior of the function near the value, not in x = 2.

While we can see that h(2) = 3 (we have a jump there). We can see that around x = 2 the function tends to zero.

From that, we conclude that:

[tex]\lim_{x \to \ 2} h(x) = 0.[/tex]

Then the correct option is the first one.

Answer:

4000

Step-by-step explanation:

200 + 200 {100

400 × 10

4000

Answer:

4000

Step-by-step explanation:

because the 200+200 are in parenthesis that shows that you will need to do it first.

so.. 200+200=400

and now the second part is asking for the square root of 100. We know that 10 times 10 is 100. This means that 10 is the square root of 100.

And for our last step they ask to multiply our two answers.

so 400 x 10= 4000

Answer:

7.97%

Step-by-step explanation:

Given data

Original Salary= $32,000

Increase= $2,550.00

percent increase= increase/original *100

Percent increase= 2,550.00/32000*100

Percent increase=  0.0796875*100

Percent increase= 7.97%

Hence the increase is  7.97%

1 7/12

Answer:

1 3/4 - 1 1/6

= 10/4 - 7/6

Lcm of 4 and 6 = 2 ×2 × 3 = 12

= (10/4) × 3 = 30/12

(7/6) × 2 = 14/12

30/12 - 14/12 = 30-13/12 = 17/12

Answer:

4791.7

Step-by-step explanation:

Answer: c=35

D=90

E=55

Step-by-step explanation:

Since d is a right angle it is 90. Take 90 and subtract it from 180 to get 90.Set them equal to 90 so 3x+11+5x+15=90

Simplify

8x+26=90

8x=64

X=8

Now take x and plug it in for each equation

3(8)+11=35

5(8)+15=55

So measured of c is 35

Measure of e is 55

And d is 90

hope this helps

Answer:

20°

Step-by-step explanation:

It's a catch. Draw a stronger line (along the circle) from V, going through Z, W, X, and getting to Y. That measures 320°.

Since the whole circle is 360° the segment YV measures 40°. Therefore, angle VXY = 20°.
