Answer: 51 students

Step-by-step explanation:

There are 600 students in this school and 34% are in 8th Grade.

The number of students in 8th grade is:

= 34% * 600

= 204 students

Then out of these 204, 1/4 walk to school. The number of students walking to school is therefore:

= 204 * 1/4

= 51 students

Answer:

B=50

Step-by-step explanation:

THE TRINGLE IS 180 DEGREE (RULE)

(X+38)+(3X-12)+(2X-2)=180

6X=180-(38-12-2)

6X=156

X=26

B=2X-2

B=2(26)-2=52-2=50

Answer:

130 ; 50% ; 25%

Step-by-step explanation:

Using te boxplot to answer the underlying questions :

Number of employees who spend $10 or less corresponds to the lower quartile, which is up to 25% of the distribution :

Total number of employees = 520

Number of employees who spend $10 or less = 25% of 520 = 0.25 * 520 = 130 employees.

Percentage of employees who spend from $10 to $45 = Interquartile range

$10 corresponds to lower quartile = 25%

$45 corresponds to upper quartile = 75%

IQR  = 75% - 25% = 50%

Percentage who spend $45 or more

$45 corresponds to the upper QUARTILE (Q3) :

45 or more = 100% - Q3 = 100% - 75% = 25%

Answer:

25

Step-by-step explanation:

as you can see test a is further away from the ruler you have to put it at 0 so that you can get your answer I am not sure if it's correct or not

Answer:

Radius, x = 80.6mm

Step-by-step explanation:

[tex]radius =\sqrt{height^2 -slant\ height^2} = \sqrt{90^2 - 40^2} = \sqrt{8100-1600} =\sqrt{6500}[/tex]

Radius = 80.6mm

Answer: (b)

Step-by-step explanation:

Given

Amelia ordered 2 large pizzas for the party

After the party, half of one pizza and three-eight of pizza is left from other pizza

Sum of the remaining pizzas

[tex]\Rightarrow \dfrac{1}{2}+\dfrac{3}{8}\\\\\Rightarrow \dfrac{4}{8}+\dfrac{3}{8}\\\\\Rightarrow \dfrac{4+3}{8}=\dfrac{7}{8}[/tex]

seven-eight is a fraction which is less than 1

Hence, less than 1 pizza is left

So, option (b) is correct.

2 X 5 = 10. 10 +3 = 13. 13 + 5 = 18.

Answer:

The answer is 152 r10

Step-by-step explanation:

There is indeed a remainder when dividing 6394 by 42.

6394 ÷ 42 = 152 with a remainder of 10, so, the remainder is 10.

Here, we have,

To determine if there is a remainder when dividing 6394 by 42,

we can perform the division and check if the result is a whole number or a decimal.

6394 ÷ 42 = 152 with a remainder of 10

Since the division does not result in a whole number,

but rather a quotient of 152 with a remainder of 10,

it indicates that there is indeed a remainder when dividing 6394 by 42.

5 liters (L) of 30% bleach solution contains 0.3×(5 L) = 1.5 L of bleach.

3 L of 50% bleach contains 0.5×(3 L) = 1.5 L of bleach, too.

Combined, you would have 8 L of solution containing 1.5 L + 1.5 L = 3 L of bleach, so the concentration of bleach is

(3 L) / (8 L) = 0.375 = 37.5%

How much reflective material is needed (without overlapping)

The question implies that, we calculate the surface area of the material.

Without overlapping, the material will have the same surface area as the block of ice.

The surface area is calculated using:

[tex]SA = 2 * (LW + WH + HL)[/tex]

Where

[tex]W = 4[/tex] --- Width

[tex]L = 2[/tex] --- Length

[tex]H = 3[/tex] --- Height

So, we have:

[tex]SA = 2 * (2 * 4 + 4 * 3 + 3 * 2)[/tex]

[tex]SA = 2 * (8 + 12 + 6)[/tex]

[tex]SA = 2 * 26[/tex]

[tex]SA = 52[/tex]

Answer:

-1/√2  

Step-by-step explanation:

According to trigonometry identity

cos(A+B) = cosAcosB - sinA sinB

Given the expression

(cos92°)(cos133°)-(sin92°)(sin133°)

This can be expressed as cos(92+133) where A = 92, B = 133

(cos92°)(cos133°)-(sin92°)(sin133°)

= cos(92+133)

= cos225

= -0.7071

= -1/√2

Hence the exact value is  -1/√2

Answer:

508sq. cm

Step-by-step explanation:

surface area of a prism = 2(lw + wh + lh)

For the larger prism

Surface area = 2(2*10 + 2 * 12 * 10*12)

Surface area = 2(20+24+120)

Surface area = 2(164)

Surface area = 328sq.cm

For the smaller prism

Surface area = 2(3*6 + 3 * 8 * 6*8)

Surface area = 2(18+24+48)

Surface area = 2(90)

Surface area = 180 sq.cm

Surface area of the figure = 328 + 180

Surface area of the figure = 508sq. cm

Answer:

Wanda's recipe needs 0.09 more cups of flour per bagel.

Step-by-step explanation:

First, you have to find the amount flour that each of them need for one bagel by dividing the cups of flour they use by the number of bagels:

Wanda: 3.54/6= 0.59 cups of flour

Eli: 2.5/5=0.5 cups of flour

Now, you have to subtract the amount of flour Eli needs from the amount that Wanda needs:

0.59-0.5=0.09

According to thiss, the answer is that Wanda's recipe needs 0.09 more cups of flour per bagel.

Answer:

10.44

Step-by-step explanation:

okay so percentages can be converted to decimals

to do this, you can either:

move the decimal space to the left twice

or

divide the percentage (in this case 58) by 100,

regardless you will get the same answer

58.0 → 5.80 → 0.58

now that you have 58% as a decimal, all you have to do is multiply it by 18

(0.58)(18) = 10.44

therefore, 58% of 18 is 10.44

The answer of the condition is Fail to Reject.

A chi-squared test (also chi-square or χ2 test) is a statistical hypothesis test that is valid to perform when the test statistic is chi-squared distributed under the null hypothesis, specifically Pearson's chi-squared test and variants thereof. Pearson's chi-squared test is used to determine whether there is a statistically significant difference between the expected frequencies and the observed frequencies in one or more categories of a contingency table.

The data is given as follow:

The experimental weight of cashews = 40 % of 20lbs

                                                                  = 8

The experimental weight of Brazil Nuts = 15 % of 20lbs

                                                                  = 3

The experimental weight of Almonds = 20 % of 20lbs

                                                                 = 4

The experimental weight of peanuts = 25 % of 20lbs

                                                                  = 5

The observed value is :

So, [tex]{\displaystyle \chi }[/tex] =[tex]\frac{(O-E)^{2}}{E}[/tex]

[tex]{\displaystyle \chi }[/tex]= [tex]\frac{(5-8)^{2}}{8} + \frac{(6-3)^{2}}{3} + \frac{(5-4)^{2}}{4} +\frac{(4-5)^{2}}{5}[/tex]

  = 4.575

pvalue = p([tex]{\displaystyle \chi }^{2}[/tex] > 4.575) = [tex]{\displaystyle \chi }^{2}[/tex] cdf(4.575, 99999, 3)

                                     = 0.208 >α

Hence, Fail to reject.
