Answer:

.40 or 40 percent

Step-by-step explanation:

Answer:

30 cm

Step-by-step explanation:

To find the perimeter you will have to use the formula L2 + W2 = A

1. Multiply the length (let's say 10 cm) by 2

       a. 20

2. Do the same for width (5 cm)

      a. 10

3. Add together

     a. 20 + 10 = 30 cm

(There is another way to do it but this is easier)

Hope this helps :)

Answer:

72 passengers

Step-by-step explanation:

What we know:

To find how many passengers are travelling alone, multiply 150 by 48%.

48% ⇒ 0.48 as a decimal

150 × 0.48 = 72

Therefore, 72 passengers are travelling alone.

I hope this helps!

Answer:

w = [tex]l + \frac{25 - l^{2}}{l - 5}[/tex]

(Anyone can correct me if I'm wrong)

Step-by-step explanation:

Before we start the solving, we can make the following statements:

Area = l x w

Area = 5x + 25

therefore,

l x w = 5x + 25

Since the question states that the length is x more than the width, so we can make the following statement:

w = l + x

With this, we can substitute it to the first statement we made, l x w = 5x + 25,

l x (l + x) = 5x + 25

[tex]l^{2}[/tex] + lx = 5x + 25

lx - 5x = 25 - [tex]l^{2}[/tex]

x(l - 5) = 25 - [tex]l^{2}[/tex]

x = [tex]\frac{25 - l^{2}}{l - 5}[/tex]

From this, we can find w by substituting it in the statement we made earlier, w = l + x,

w = [tex]l + \frac{25 - l^{2}}{l - 5}[/tex]

Answer:

mx = y

or

y = mx

Step-by-step explanation:

If she pays m per share, and x represents each share, you will multiply m and x. If she sold all them for the value of y. Then you set mx equal to y.

mx = y

or

y = mx

Hey there!

Your answer is [tex]2(\frac{x}{6} )[/tex]

"Double" represents multiplying by 2. "the quotation of a number (x) and 6" represents division. So, we can double [tex]\frac{x}{6}[/tex], which gives us [tex]2(\frac{x}{6} )[/tex].

Have a terrificly amazing day! :D

For the shower multiply the amount of water per minute by number of minutes:

10.6 x 7 = 74.2 liters.

Calculate volume of the tube and the amount of water in it:

35 x 40 x 120 = 168,000 cubic cm.

Convert to liters:

168,000/ 1000 = 168 liters.

Savings = 168 - 74.2 = 93.8 liters

Answer:

1) P(258.5-cm < M < 259-cm) = 8.71%.

2) P17 = 125.57cm

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

Question 1:

Mean of 258.5-cm and a standard deviation of 2.3-cm, which means that [tex]\mu = 258.5, \sigma = 2.3[/tex]

Find the probability that the average length of a randomly selected bundle of steel rods is between 258.5-cm and 259-cm.

This is the pvalue of Z when X = 259 subtracted by the pvalue of Z when X = 258.5.

X = 259

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

[tex]Z = \frac{259 - 258.5}{2.3}[/tex]

[tex]Z = 0.22[/tex]

[tex]Z = 0.22[/tex] has a pvalue of 0.5871

X = 258.5

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

[tex]Z = \frac{258.5 - 258.5}{2.3}[/tex]

[tex]Z = 0[/tex]

[tex]Z = 0[/tex] has a pvalue of 0.5

0.5871 - 0.5 = 0.0871

0.0871*100% = 8.71%. So

P(258.5-cm < M < 259-cm) = 8.71%.

Question 2:

Mean of 127.1-cm and a standard deviation of 1.6-cm, which means that [tex]\mu = 127.1, \sigma = 1.6[/tex]

Find P17, which is the average length separating the smallest 17% bundles from the largest 83% bundles.

This is the 17th percentile, which is X when Z has a pvalue of 0.17. So X when Z = -0.954.

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

[tex]-0.954 = \frac{X - 127.1}{1.6}[/tex]

[tex]X - 127.1 = -0.954*1.6[/tex]

[tex]X = 125.57[/tex]

P17 = 125.57cm

[tex]{ :{ \implies { \tt{ \blue{ \frac{1}{4} x + 3 - \frac{1}{3} x + ( - 2)}}} }}\\ \\ \\ { : { \implies{ \blue{ \tt{ \frac{1}{4} x - \frac{1}{3} x + 3 - 2}}}}}[/tex]

[tex]{ : { \implies{ \tt{ \blue{ \frac{1}{4} x - \frac{1}{3} x + 1}}}}} \\ \\ \\ { : { \implies{ \tt{ \blue{ \frac{3x - 4x + 12}{12}}}}}} [/tex]

[tex]{ :{ \implies{ \blue{ \tt{ \frac{12 - x}{12}}}}}} \\ \\ \\ { : { \implies{ \blue{ \tt{1 - \frac{x}{12}}}}}} [/tex]
