Answer:

Step-by-step explanation:

So you have to remember, area is LxW - Lenth x Width.

Also remember base is bxh - Base x height.

T he rectangle has a area already which is 3x3 = 6 but remember you also have to find the base. So,

you do Area = 50.4 yd²

Step-by-step explanation:

Base dimension of container = 4⅕ by 1⅓ yd

Array: 3 * 3 containers without space

Area covered by the containers

First, it'll be assumed that the container has a rectangular base.

The dimension of the base is measured out as follows:

Length, L = 4⅕ yd

Width, W = 1⅓ yd

Note that this can also be interchanged.

Next, is to calculate the area of 1 container..

Area = 4⅕ yd * 1⅓ yd

Convert mixed fractions to improper fraction

Area = 21/5 * 4/3 yd²

Area = 84/15 yd²

Area = 28/5 yd²

Area = 5.6 yd²

Next, is to calculate the area of the 3 by 3 containers.

Given that the container formed a 3 by 3 array;

This means that there 3 * 3 containers

3 * 3 = 9 containers.

Area of the 9 containers = 9 * Area of 1 container.

Area = 9 * 5.6 yd²

Area = 50.4 yd²

the area covered by the containers is 50.4 yd²

Assume that adults have IQ scores that are normally distributed with a mean of mu equals μ=105 and a standard deviation sigma eq

Over [174]

The probability that a randomly selected adult has an IQ less than

135 is 0.97725

Step-by-step explanation:

Assume that adults have IQ scores that are normally distributed with a mean of mu equals μ = 105 and a standard deviation sigma equals σ = 15

We need to find the probability that a randomly selected adult has an IQ less than 135

For the probability that X < b;

Convert b into a z-score using z = (X - μ)/σ, where μ is the mean and σ is the standard deviation
Use the normal distribution table of z to find the area to the left of the z-value ⇒ P(X < b)

∵ z = (X - μ)/σ

∵ μ = 105 , σ = 15 and X = 135

∴ $z=\frac{135-105}{15}=2$

- Use z-table to find the area corresponding to z-score of 2

∵ The area to the left of z-score of 2 = 0.97725

∴ P(X < 136) = 0.97725

The probability that a randomly selected adult has an IQ less than

135 is 0.97725

Para ir a visitar a los abuelos Paula y Mario se ponen de acuerdo en que Paula vaya cada 5 días y Mario cada 6 días. Si coincidi

photoshop1234 [79]

Answer:

a) January 24(24 de Enero)

b) Paula will have made 5 visits(Paula habrá hecho 5 visitas). Mario will have made 4 visits(Mario habrá hecho 4 visitas).

Step-by-step explanation:

When two events, A and B, happen every x and y days, respectively, they will happen on the same day in each lcm(x,y) days. lcm(x,y) is the lesser common multiple of x and y which is not 0.

In this question:

Paula each 5 days

Mario each 6 days

Multiples of 5: {0, 5, 10, 15, 20,25,30, ...}

Multiples of 6: {0, 6, 12, 18, 24, 30, ...}

a) ¿Cuándo volvieron a coincidir?

lcm(5,6) = 30

30 days from December 24, which is January 24(24 de Enero).

b) ¿Cuántas visitas habrá hecho cada uno?

Paula visits each 5 days.

30 is 6th non-zero multiple of 5. This means that on January 24 will be her 6th visit. So she will have made 5 visits.

30 is the 5th non-zero multiple of 6. This means that on January 24 will be her 5th visit. So he will have made 4 visits.

Answer:

a. 59.73_3 ft²/h

b. 5.093 h

c. $149.95

Step-by-step explanation:

a. The specified unit rate is ...

... (square ft)/(hour) = (10.5 ft)(12.8 ft)/(2.25 h) = 134.4 ft²/2.25 h = 59.73_3 ft²/h

b. The wall area is the product of the perimeter of the room and its height:

... A = (2(l+w))h = 2(10.2 ft + 6.7 ft)·(9 ft) = 304.2 ft²

At the above rate, the time required is ...

... (304.2 ft²)/(59.73_3 ft²/h) ≈ 5.093 h

c. If the charge is proportional to the time required, the charge for painting the basement walls will be ...

... $66.25/(2.25 h) = charge/(5.093 h)

... (5.093 h)/(2.25 h)×$66.25 = charge ≈ $149.95

_____

Note that the number 5.093 shown here is a representation of the number 5.09263392857 used in the calculations. Only the final numbers are rounded in each case.

The underbar in 59.73_3 is a text representation of the overbar usually used to signify the repeating digits in a repeating decimal:

... $59.7\overline{3}$
