The value of x is option B) 6.

<u>Step-by-step explanation:</u>

The given equation is -162=-3+4(6 - 7x).

You can see the bracket on the right of the equation. To remove the bracket, we must use the distributive property.

The distributive property is to multiply the number outside the bracket with each term present inside the bracket.

Here, the number outside the bracket is 4 ans we have to multiply it with 6 and -7x which are inside the bracket.

The simplified form is,

⇒ -162 = -3 + 24 - 28x

Keep x term alone on one side and bring all the constant terms to the other side of the equation.

⇒ -162 = 21 -28x

⇒ 28x = 21+162

⇒ 28x = 183

Divide by 28,

⇒ x = 183/28

⇒ x = 6.5

x can be approximated to 6 which is option B)

Therefore, the value of x is 6.

Alexxx [7]

Question options:

The standard deviation is 0.0998. The 10% condition is not met because there are less than 250 fish in the river.

The standard deviation is 0.0998. The 10% condition is met because it is very likely there are more than 250 fish in the river.

The standard deviation is 0.9002. The 10% condition is met because it is very likely there are more than 250 fish in the river.

The standard deviation is 0.9002. The 10% condition is not met because there are less than 250 fish in the river.

We are unable to determine the standard deviation because we do not know the sample mean. The 10% condition is met because it is very likely there are more than 250 fish in the river

Answer:

The standard deviation is 0.0998. The 10% condition is met because it is very likely there are more than 250 fish in the river

Explanation:

Formula to calculate standard deviation = √p(1-p)/n

Given p= population proportion

n= sample size

From the question,

We are given p(population proportion of catfish in the river)= 0.47

n(sample size of fish collected from river) = 25

The standard deviation using the formula above = √0.47(1-0.47)/25

= 0.0998

The 10% condition demands that a sample size be not less than 10% of the population

To check if the 10% condition was met, we know that a river will likely have up to 250 fish in it and so,

10% of 250= 0.10×250=25 fish

Therefore the option B chosen is correct

Answer:

Unit rates are expressed as a quantity of 1, such as 3 feet per second or 6 miles per hour, they are called unit rates.

In the given table shows the number of pictures taken and how much time it took.

For first camera;

Number of pictures (unit rate) per second = $\frac{15}{3} =5$ pictures.

For second Camera:

Number of picture per second = $\frac{48}{8} =6$ pictures.

For third Camera:

Number of picture per second = $\frac{18}{6} =3$ pictures.

The camera that takes picture the fastest is, Second Camera.

(a)

As per the given statement: At Davidson's Bike rentals, it costs $29 to rent a bike for 8 hour.

⇒ unit rate per dollar = $\frac{Number of hours }{Total cost} = \frac{8}{29} = 0.2758620$ hours

Therefore, 0.227 hours (nearest to hundredths) of bike use does a customer get per dollar.

(b)

Jessica bought 18 pounds of sugar for $10.

unit rate per dollar = $\frac{18}{10} =1.8 pounds$

therefore, 1.8 pounds of sugar did she get per dollar.

The original square has the area (8 in)^2 = 64 in^2.

If we mult. this area by 36, we get the area of a larger square 2304 in^2.

The new side length is sqrt(2304 in^2), or 48. In other words, the original square has side length 8 in, but the 'new' square has side length 48 in.
