I can’t tell if 3 is a dilation or not!

Answer:

X = 1

Step-by-step explanation:

You first divide each side by 3 leaving you with X+5 = 6. Then you take the 5 to the other side leaving you with X=6-5 as the 5 changes from positive to negative. So 6-5=1 so X=1

Step-by-step explanation:

Approximately normal with mean of 140 seconds and standard deviation of 10 seconds.

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean  and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean.

here, we have,

Given,

In the question:

The times to pop a regular bag of microwave popcorn without burning it are Normally distributed with a mean time of 140 seconds and a standard deviation of 20 seconds. The times to pop a mini bag of microwave popcorn without burning it are Normally distributed with a mean time of 90 seconds and a standard deviation of 15 seconds.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Mean of 140, standard deviation of 20, sample of 4:

By the Central Limit Theorem, the distribution is approximately normal.

Mean is the same, of 140.

n = 4 , σ = 20, thus:

s = σ /√n  

 = 20/√4

 = 10

Thus, the correct answer is:

Approximately normal with mean of 140 seconds and standard deviation of 10 seconds.

Answer:

20.05feet

Step-by-step explanation:

Given data

Circumference= 63feet

The expression for circumference is

C= 2πr

substitute

63= 2*3.142*r

63= 6.284r

r= 63/6.284

r=10.025

Hence the diameter is

=10.025*2

Answer: It is not.

Step-by-step explanation:

The salaries paid to the various departments of a company are usually different as some departments get paid more than others. For instance, in a manufacturing company, the R&D department would on average, get paid more than members of the Cleaning department.

Asking members of only one department therefore, about their pay satisfaction would not bring about a reasonable result because it would not be indicative of the thoughts of members of the other departments who are not being paid the same.

The equivalent expression in standard form is 2x² + 7x + 5.

An expression is combination of variables, numbers and operators.

To write the expression in standard form, we need to simplify it by multiplying the two factors using the distributive property of multiplication:

(2x + 5)(x + 1) = 2x² + 2x + 5x + 5

Combining like terms, we get:

(2x + 5)(x + 1) = 2x² + 7x + 5

Therefore, the equivalent expression in standard form is 2x² + 7x + 5.

Answer:

Distance cover by Brent in 2 Lap = 104 meter

Step-by-step explanation:

Given:

Length of football field = 14 m

Width of football field = 12 m

Find:

Distance cover by Brent in 2 Lap

Computation:

Distance cover by Brent in 2 Lap = 2 x Perimeter of rectangular field

Perimeter of rectangle = 2[l+b]

Perimeter of rectangular field = 2[14 + 12]

Perimeter of rectangular field = 2[26]

Perimeter of rectangular field = 52 m

Distance cover by Brent in 2 Lap = 2 x Perimeter of rectangular field

Distance cover by Brent in 2 Lap = 2 x 52

Distance cover by Brent in 2 Lap = 104 meter

Answer:

1/3

Step-by-step explanation:

Answer:

x=12

Step-by-step explanation:

4x+16=64

to isolate x, take 16 from both sides

4x+ 16(-16)=64-16

4x=48

divide 4 on each side

4x/4=x

48/4=12

x=12

The solution of the equation 4x+16= 64 is x = 12.

The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of those variable would give a true mathematical statement.

For this case, we've to solve for x, the equation [tex]4x + 16 = 64[/tex]

Subtracting 16 from both the sides:

[tex]4x + 16 - 16 = 64 - 16\\4x + 0 = 48\\4x = 48[/tex]

4x is actually 4 times x, and is written in short, where the multiplication sign is hidden. This is usually done when variables like x,y are there.

Dividing both the sides by 4, we can get x on one side, and rest of the constant values on the other side.

[tex]\dfrac{4x}{4} = \dfrac{48}{4}\\\\1 \times x = 12\\x = 12[/tex]

(since 1 times any number is that number itself, and as x represents a number, so we got 1 times x =x).

Thus, the solution of the equation 4x+16= 64 is x = 12.

Answer:

35 mph

Step-by-step explanation:

As you might have learned in your physics class, the average speed of a car in mph is 50. You should write this down on some paper.

After writing it down, we need to look at what the problem is asking us, so we don't get confused. " How fast was he going on the way to the bookstore?"

This means that we need to calculate his mph speed on the way to the bookstore by subtracting something.

50 mph=Average

Alternate Route= -15

After you have written THAT down in your notes, you need to ask yourself,

"What is 50-15?"

Calculating 50-15 will make the "15 mph slower" show up and calculating that with the average will get you your answer.

50-15 is 35

its d cause there is actually 208 nickles and if u ad 8 more it gives u 216.

Answer: D.

Step-by-step explanation:

52x4=208

Since we know she has 4 times as many nickels as dimes(52), we just have to multiply 52x4 to get 208 nickels

208+8=216

We know that she has 8 more quarters than nickels(208) so we have to add 8 to 208 to get 216 quarters
