The equation has 2 real roots

The equation is given as:

[tex]y = 3x^2 + 12x - 12[/tex]

Calculate the determinant using

d = b^2 - 4ac

So, we have:

d = 12^2 - 4 * 3 * (-12)

Evaluate

d = 288

Because d > 0

i.e. 288 is greater than 0

Then it means that the equation has 2 real roots

The correct option is C which is The z-statistic is 3.32, so the null hypothesis should be rejected. One can reject the null hypothesis.

When there are two possibilities then we calculate the null hypothesis if the hypothesis is true hypothesis is accepted if it is

To conduct a hypothesis test for the above situation. We define the null hypothesis and the alternative hypothesis.

The null hypothesis is the claim that the average commute time to downtown is 20 minutes while the alternative hypothesis is a contradiction of the null hypothesis which is that the average commute time to downtown is not 20 minutes.

i.e. H0: μ = 20 and H1:  μ ≠ 20.

The z-statistics is given by (sample mean - hypothesized mean) divided by (standard deviation divided by the square root of the sample size).

i.e.

[tex]z= \dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}[/tex]

x = 26,  [tex]\mu[/tex] = 20, [tex]\sigma[/tex] = 7 and n = 15 putting the values in the question we will get the z-score value.

[tex]z = \dfrac{26-20}{\dfrac{7}{\sqrt15}}[/tex]

z = 6 / 1.807

z = 3.32

Therefore, the z-statistic is 3.32, so the null hypothesis should be rejected. Because the calculated value of z (3.32) is greater than the table value of z (1.96).

Answer:

x = 1

Step-by-step explanation:

Simplifying

7(x + 1) + -2 = 5(x + 1) + 2

Reorder the terms:

7(1 + x) + -2 = 5(x + 1) + 2

(1 * 7 + x * 7) + -2 = 5(x + 1) + 2

(7 + 7x) + -2 = 5(x + 1) + 2

Reorder the terms:

7 + -2 + 7x = 5(x + 1) + 2

Combine like terms: 7 + -2 = 5

5 + 7x = 5(x + 1) + 2

Reorder the terms:

5 + 7x = 5(1 + x) + 2

5 + 7x = (1 * 5 + x * 5) + 2

5 + 7x = (5 + 5x) + 2

Reorder the terms:

5 + 7x = 5 + 2 + 5x

Combine like terms: 5 + 2 = 7

5 + 7x = 7 + 5x

Solving

5 + 7x = 7 + 5x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5x' to each side of the equation.

5 + 7x + -5x = 7 + 5x + -5x

Combine like terms: 7x + -5x = 2x

5 + 2x = 7 + 5x + -5x

Combine like terms: 5x + -5x = 0

5 + 2x = 7 + 0

5 + 2x = 7

Add '-5' to each side of the equation.

5 + -5 + 2x = 7 + -5

Combine like terms: 5 + -5 = 0

0 + 2x = 7 + -5

2x = 7 + -5

Combine like terms: 7 + -5 = 2

2x = 2

Divide each side by '2'.

x = 1

Simplifying

x = 1

Answer:

Hello! The answer is x = 1.

Step-by-step explanation:

To solve this equation, we need to find x.

The first step in approaching this problem would be to use the distributive property:

7(x + 1) - 2 = 5(x + 1) + 2 will turn into:

7x + 7 - 2 = 5x + 5 + 2

Now, you can combine like terms on each side of the equation:

7x + 5 = 5x + 7

Now, you want to get the x's on one side and the whole numbers on the other side. In order to do this, we will subtract 5 from both sides and subtract 5x from both sides:

7x + 5 = 5x + 7

-5x -5   -5x  -5

This will leave us with:

2x = 2

We will have to now divide both sides by 2 to get x by itself:

2x = 2

--     --

2     2

This leaves us with the result: x = 1

Answer:

$9450

Step-by-step explanation:

Answer:

A = $9,450.00

A = P + I where

P (principal) = $9,000.00

I (interest) = $450.00

Calculation Steps:

First, convert R as a percent to r as a decimal

r = R/100

r = 5/100

r = 0.05 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 9,000.00(1 + 0.05/1)(1)(1)

A = 9,000.00(1 + 0.05)(1)

A = $9,450.00

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $9,000.00 at a rate of 5% per year compounded 1 times per year over 1 years is $9,450.00.

Option A is accurate. The points were plotted with the coordinates (x, log) y), and they are (3, 2.097), (4, 2.796), and (5, 3.495).

Answer:

13/40

Step-by-step explanation:

Rewrite a percentage as a decimal: [tex]\frac{32.5}{100}[/tex]

Convert decimals to integers: [tex]\frac{325}{100}[/tex]

Reduce the fraction: [tex]\frac{13}{40}[/tex]

Answer: [tex]\frac{13}{40}[/tex]

32.5% as a fraction in simplest form is 13/40.

Here we have to find fractional form of 35 percent

Since we knw that,

A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

To convert a percentage to a fraction,

we can simply write it as a fraction with a denominator of 100.

Then,

we simplify the resulting fraction to its simplest form.

For 32.5%,

we can write this as,

⇒ 32.5/100

Now, we can simplify this fraction by dividing both the numerator and denominator by their greatest common factor (GCF).

The GCF of 32.5 and 100 is 12.5,

so we can divide both by 12.5,

⇒ 32.5/100 = (32.5 ÷ 12.5) / (100 ÷ 12.5)

                   = 13/40

Therefore, 32.5% as a fraction in simplest form is 13/40.

You may now choose any point on the graph (the horizontal line represents a point for width, and the vertical line represents a point for height) and put it into the specified formula. Let's test the two supplied points (2, 1):

Now, 2 is on the horizontal line, so we put it in for width, and 1 is on the vertical line, so we plug that in for height. When we do it, we get:

1 = C * 2
