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%

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%

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

Step-by-step explanation:

major arcs are greater than 180 degrees. 180 degrees is a semicircle. Arc LJK is larger than a semicircle, therefore larger than 180 degrees. and it includes angle 2

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

Step-by-step explanation:

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

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.

Step-by-step explanation:

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

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

Step-by-step explanation:

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.
