Answer 1

Answer:

Answer:

0.0099

Step-by-step explanation:

To find the area under the standard normal curve to the right of $z = 2.33$ , you're essentially looking for the probability that a randomly chosen value from the standard normal distribution is greater than 2.33.

Using a standard normal distribution table or a calculator, you can find this probability directly. The value you're looking for is the complement of the cumulative distribution function (CDF) at $z = 2.33$ , which gives you the area to the left of $z = 2.33$ . To find the area to the right, you subtract this value from 1.

In other words, you want to find $1 - P(Z \leq 2.33)$ , where $Z$ is a standard normal random variable.

Using a calculator or a standard normal distribution table, you will find that $$ P(Z \leq 2.33) \approx 0.9901 $.$

So, the area under the standard normal curve to the right of $z = 2.33$ is approximately:

$1 - 0.9901 = 0.0099$

Rounded to four decimal places, the answer is approximately 0.0099.

65% of 80 is what number

Answers

Answer:

Step-by-step explanation:

We can find the percent of a number by converting the percent to a decimal.

65%=0.65

80(0.65)=52

To find 65% of 80, first write 65% as a decimal by moving the decimal point 2 places to the left and we will get .65. Next, the word "of" means multiply, so we have (.65) (80) = 52.

Therefore, 65% of 80 is 52.

Which statement is true about the equation fraction 3 over 4z − fraction 1 over 4z + 1 = fraction 2 over 4z + 1?It has no solution.
It has one solution.
It has two solutions.
It has infinitely many solutions.

Answers

Answer:

It has no solution.

Step-by-step explanation:

I just did the test and got this right (as a matter of fact, I got 100% ^^)

It has no solution because no matter how much you multiply the two fractions to the left, it will always equal to 1/2, and 2/4, no matter how many times you multiply it, will always equal to 1/2 as well. Therefore, since those two cancel out, and the leftover numbers in the equation aren't the same, there is no possible solution for this equation.

The solution is Option A.

The equation has no solutions

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

( 3/4z ) - ( 1/(4z+1 ) ) = 2/ (4z + 1 ) be equation (1)

Adding ( 1/(4z+1 ) ) on both sides of the equation , we get

( 3/4z ) = ( 2 + 1 ) / (4z + 1 )

On further simplification , we get

( 3/4z ) = 3/(4z + 1 )

Divide by 3 on both sides of the equation , we get

1/4z = 1/( 4z+1 )

Taking reciprocals on both sides of the equation , we get

4z = 4z + 1

Subtracting 4z on both sides of the equation , we get

1 ≠ 0

Hence , the equation has no solutions

How much will you save per lb, by buying the least expensive? Round to the nearest cent. 2.5 lbs for $8.75 or 3 pounds for $9.75.

Answers

Answer:

$0.25 per pound.

Step-by-step explanation:

Let us find unit rate for both quantities.

$\text{Price per pound}=\frac{8.75\text{ dollars}}{2.5\text{ pound}}$

$\text{Price per pound}=3.5\frac{\text{ dollars}}{\text{ pound}}$

Therefore, cost of per pound for first given rate is $3.5.

Now let us find unit rate for second quantity.

$\text{Price per pound}=\frac{9.75\text{ dollars}}{3\text{ pound}}$

$\text{Price per pound}=3.25\frac{\text{ dollars}}{\text{ pound}}$

We can see that price for second quantity is less than 1st. To find the savings per pound we will subtract 3.25 from 3.5.

$\text{Savings per pound}=3.50-3.25$

$\text{Savings per pound}=0.25$

Therefore, we will save $0.25 per pound by buying the least expensive.

0.25
