OH NO!
It's been a great morning at school so far. Your class has been to PE
and math class and now it is time for lunch, As you are walking
toward the cafeteria, an announcement comes over the intercom.
"All of the student lunch IDs have been lost! In order to get your
lunch today you are going to need to solve a set of problems to
retrieve the codes before you'll be able to get your lunch!"
You and your group must work together to solve the problems and
get your codes to eat lunch!

Answer:

0.254

Step-by-step explanation:

Given that:

Percentage of those having health insurance = 71%

p = 71 / 100 = 0.71

Number of adults selected at random, n = 4

Probability that 4 selected have health insurance :

p^n = 0.71^4 = 0.25411681

= 0.254

Answer:

yes, all of it is correct

Step-by-step explanation:

For the two triangles to be congruent, you would need the following angles and lengths to be congruent with each other.

Answer:

So we have this equation:

r/10 + 4 = 5

FIrst, we can substract 4 in both sides

r/10 + 4 - 4 = 5 - 4

r/10  = 1

Now, we can multiply both sides per 10:

r/10 * 10 = 1 * 10

r = 10

And we know that r = 10, and that's the result of the equation.

Question #2

21 Miles per gallon

Divide the number of gallons by the amount of gas to get miles per gallon.

252/12=21 miles per gallon

Answer:

4,055

Step-by-step explanation:

9514 1404 393

Answer:

  11 years, 7 months

Step-by-step explanation:

When the investment reaches its desired value, it will be 3 times the original amount. So, we are looking for the number of half-month periods (n) of compounding such that ...

  (1 +0.095/24)^n = 3

Taking logarithms, we have ...

  n·log(1.003958333...) = log(3)

  n = log(3)/log(1.009358333...) ≈ 278.09

This is 278.09/24 ≈ 11.59 years.

It will take about 11 years and 7 months for the investment to reach the desired value.

__

Additional comment

The amount will be about tzs 2,758 short after 11 years 7 months. It will exceed the desired amount after 2 more days' interest is added.

Answer:

56

Step-by-step explanation:

If we split this figure to 2 parts, we figure the area based upon this composite figure.

1 figure is 10x4(rectangle)

the other figure is a 4x4 square (Note we subtract 8 by 4 because we don't want overlapping area)

After that we find the area of those to figures then we add them up

(4x4)+(10x4)

16+40

132 is what percent of 880? = 15.

Answer:

w<50

c≤30

6w+2c≥320

Step-by-step explanation:

W stands for the car wash, and C stands for the cakes. Naturally, it would be 7w+4c≥320 but each cake costs $2 to make and each car wash costs $1 per car. This makes the system 6w+2c≥320. They will wash less than(<) 50 cars and bake no more than(≤) 30 cakes. I hope this helped :).

To solve the problem we must know about Expressions.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Given to us

Earning per car wash = $7

Earning per cake  = $4

Cost of supplies per car wash = $1

Cost of cake = $2

They will wash less than 50 cars and

Bake no more than 30 cakes

They want to raise at least $320

Assumption

Let the number of cakes they sold be represented by x, and the number of car washes they did be represented by y.

Profit from Car wash

= Earning per car wash - Cost of supplies per car wash

= $7 - $1

= $6

Profit from Cake

= Earning per Cake - Cost of a cake

= $4 - $2

= $2

The system that represents profit

$320 = ($6)y + ($2)x

320 = 6y + 2x

As it is given that they will not make more than 30 cakes, therefore,

x ≤ 30

As it is given that they will wash less than 50 cars.

y < 50

Hence, the following equations can represent the system,

Answer:

0.82% probability that the average time it takes to complete both homework assignments is greater than 82 minutes

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Math homework:

[tex]\mu_M = 30, \sigma_M = 3[/tex]

Arts homework:

[tex]\mu_A = 40, \sigma_A = 4[/tex]

What is the probability that the average time it takes to complete both homework assignments is greater than 82 minutes?

Here, we have a sum of normal variables. The mean will be the sum of the means, while the standard deviation is the square root of the sum of the variances. So

[tex]\mu = \mu_M + \mu_A = 30 + 40 = 70[/tex]

[tex]\sigma = \sqrt{\sigma_M^2 + \sigma_A^2} = \sqrt{3^2+4^2} = 5[/tex]

This probability is 1 subtracted by the pvalue of Z when X = 82. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{82 - 70}{5}[/tex]

[tex]Z = 2.4[/tex]

[tex]Z = 2.4[/tex] has a pvalue of 0.9918

1 - 0.9918 = 0.0082

0.82% probability that the average time it takes to complete both homework assignments is greater than 82 minutes

Answer:

Perimeter = 26 cm. Area =

Step-by-step explanation:

The rectangle has a width of 4 cm and the square has a length of 9. cm, so  to make them have the same area you make the length of the rectangle 9 cm and the square have a width of 4 cm.

then each shape will have two sides that are 9 cm and two sides that are                 4 cm.

Perimeter

9 + 9 = 18

4 + 4 = 8

18 + 8 = 26

the perimeter is 26 cm.

Area

9 x 4 = 36

the area is 36 cm.

Answer:

Width is 4cm and length is 20.25, so perimeter is 48.5

Step-by-step explanation:

Square has same length for each side

Area for the Square 9 x 9 = 81

So find another number that adds up to the area of the square

Area for Rectangle 4 x 20.25 = 81

Width for Rectangle is 4cm and length is 20.25, so perimeter is 48.5

Should be pretty easy if you have a calculator, It'll just take a couple more minutes :D
