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

Answer:

A probability of 0.254 should replace the "?" in the table

Step-by-step explanation:

We have the probabilities for the time of the day when each person begins a trip, during a 24-hour period.

The sum of these probabilities has to be 100% = 1.

The probabilities are of: 0.004, 0.033, 0.144, 0.234, 0.208, ?, 0.123

Since their sum has to be 1, we can find ?. So

0.004 + 0.033 + 0.144 + 0.234 + 0.208 + ? + 0.123 = 1

0.746 + ? = 1

? = 1 - 0.746

? = 0.254

A probability of 0.254 should replace the "?" in the table

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

56

Answer and explanation:

Given that there is 45% off original price of outdoor furniture and price is represented by p

Discount on original price of outdoor furniture = 45% of p=0.45×p=0.45p

Therefore post sale price(after discount) of outdoor furniture can be represented by (1-0.45)p=0.55p

Answer:

0.8401 = 84.01% probability that there is at least one business passenger.

Step-by-step explanation:

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

In this question:

Samples of 5, so [tex]n = 5[/tex]

90 passengers, so [tex]N = 90[/tex]

27 traveling on businnes, so [tex]k = 27[/tex]

Probability that there is at least one business passenger.

Either none are on business, or at least one is. The sum of these probabilities is 100% = 1.

Probability of none on business:

[tex]P(X = 0) = \frac{C_{27,0}*C_{63,5}}{C_{90,5}} = 0.1599[/tex]

Probability of at least one business passenger:

[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.1599 = 0.8401[/tex]

0.8401 = 84.01% probability that there is at least one business passenger.

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:

x=18.5 y=14.2

Step-by-step explanation:

The unmarked angle for the top/x triangle is 109 (all angles add up to 180, 180-50-21=109)

Use cosine rule:

(a/sina)=(b/sinb)

(x/sin109)=(15/sin50)

(x/sin109)=19.58110934

x=18.51430261

The top-most angle of the bottom/y triangle is 71 (angles on a straight line are 180, 180-109=71)

The righthand angle of the bottom/y triangle is 19 (angles in a triangle add to 180, 180-71-90=19)

Use cosine rule again:

(a/sina)=(b/sinb)

(y/sin71)=(15/sin90)

y/sin71=15

y=14.18277863
