Answer:

2nd answer is correct.

Step-by-step explanation:

z² = 0.36

z² = [tex]\frac{36}{100}[/tex]

z² = [tex]\frac{6 * 6}{ 10 *10}[/tex]

z = ± √ ( [tex]\frac{6 * 6}{ 10 *10}[/tex] )

z  = ± [tex]\frac{6}{10}[/tex]

z = ± 0.6

Therefore,

z = + or - 0.6

Answer:

Step-by-step explanation:

The 73 customers who spend money in this store if a MOE of at most 0.075 with 80% confidence.

MOE is an error that provides an estimate of the percentage of errors in real statistical data.

The formula for finding the MOE:

MOE = z x s/√n

Where ,

Z = the z-score at the confidence interval

s =  the standard deviation

n = the number of samples.

We have p = 0.50 MOE = 0.075

Z = 1.282 at 80% confidence

0.075 = 1.282 x √0.50(1- 0.50)/ n

After solving,

n = (0.5)(0.5)/(0.0585)²

n = 73

Thus, the 73 customers who spend money in this store if a MOE of at most 0.075 with 80% confidence.

The length of the diagonal of Stacy’s ceiling is 30√2 or 42.43

Step-by-step explanation:

a² + b² = c²

30² + 30² = c²

900 + 900 = c²

√1,800 = √c²

30√2 = c

Answer:

Using PEMDAS we can see that P or parenthesis is first so we would subtract 5 from 5 in the beginning.  That would result in a 0 which would then get multiplied with 12 to still have 0.

[tex]12(5-5) + 3 * 5[/tex]

[tex]12(0) + 3 * 5[/tex]

[tex]0 + 3 *5[/tex]

Now that we completed that part, the only thing that we have left to do is to multiply the last two numbers, 3 and 5.

[tex]3*5[/tex]

[tex]15[/tex]

Therefore, our final solution is 15.

Hope this helps!

The true statement about the rectangle  is A. If w is 12 inches, then l is 10 inches

The given parameters are:

The perimeter of a rectangle is:

P = 2(L + W)

So, we have:

2(L + W) = 44

Divide by 2

L + W = 22

The area is calculated as:

A = LW

This gives

LW = 120

Express 120 as 12 * 10 and 10 * 12

LW =12 * 10 or LW = 10 * 12

By comparison, we have:

L = 12 and W = 10 or L = 10 and W = 12

When these values are substituted in L + W = 22, we have:

10 + 12 = 22 and 12 + 10 =22

This means that the dimensions of the rectangle are 10 by 12 inches or 12 by 10 inches

Hence, the true statement is A. If w is 12 inches, then l is 10 inches

Based on the statistics, an average American spends $299.7 on lotteries each year

The population is given as:

Population = 325 million

23% are under the age of 18.

This means that this category is not eligible to play lotteries.

The eligible population is:

Eligible = (1 - 23%) * 325 million

Evaluate

Eligible = 250.25 million

The total amount is given as:

Total = $75 billion

So, the amount spent by each is:

Amount = Total/Eligible

This gives

Amount = $75 billion/250.25 million

Evaluate

Amount = $299.7

Hence, an average American spends $299.7 on lotteries each year

The nth term of the arithmetic sequence 300,250,200 is 350-50n if the common ratio is -50

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

We have an arithmetic sequence:

300,250,200

The first term a = 300

Common difference d = 250-300 = -50

nth term:

A(n) = a + (n-1)d

A(n) = 300 + (n-1)(-50)

A(n) = 300 -50n + 50

A(n) = 350—50n

Thus, the nth term of the arithmetic sequence 300,250,200 is 350-50n if the common ratio is -50

I need the question to answer please :)

Answer:

PEMDAS.

1. PARENTHESIS

2. EXPONENTS

3. MULTIPICATION

4. DIVISION

5. ADDITION

6. SUBTRACTION

Follow the steps of BEDMAS:

B = Brackets

E = Exponents

D = Division

M = Multiplication

A = Addition

S = Subtraction

Let's try 1) with these steps.

5 - 6 + 2(3)

We can see there are brackets. When a number is placed near a bracket, it means we need to multiply.

2 x 3 = 6

Let's check our expression.

5 - 6 + 6

We can see that there is addition and subtraction. When we have addition and subtraction together we can solve left to right. The same applies to multiplication and division.

So let's solve the rest of it.

5 - 6 = -1

-1 + 6 = 5

5 is the answer to 1).

Now I hope you can solve the rest accordingly with my help. If you are in a time constraint or genuinely don't feel like doing math, understandable. In that case, simply use any online scientific calculator :)

The arc length can be found using the formula, ∅ × r, which is: (5π)/3.

Arc length = ∅ × r, where ∅ is the central angle in radians, and r is the radius of the circle.

Given the following:

Length of the arc = 60° × π/180 × 5 = (60 × π × 5)/180

Length of the arc = (300π)/180 = (5π)/3
