C. k = 5/2
D. k = 2

Thank you in advance for your help!

Answers

Answer:

Option A is correct

k = 2/5

Step-by-step explanation:

The rule of dilation with scale factor k is given by:

$k = \frac{\text{Image length}}{\text{original length}}$

As per the statement:

Line AB has a length of 5 cm. The line segment is dilated to produce line A'B', which has a length of 2 cm.

⇒original Length (AB)= 5 cm

and

Image length (A'B') = 2 cm

Apply the rule of dilation we have;

$k = \frac{\text{A'B'}}{\text{AB}}$

Substitute the given values;

$k = (2)/(5)$

Therefore, the scale factor of the dilation is, 2/5

The correct answer is A. k = 2/5

Justine filled quart jars with 248 pints of juice. How many quart jars did Justine need?

Answers

124 quart jars.
2 pints are in a quart.
To have 248 pints of juice.
Take 248 divided 2 and that gets you 124 quart jars

124 jars cuz 248=124

a random sample of 130 students is chosen from a population of 4,500 students. if the mean iq in the sample is 120 with a standard deviation of 5, what is the 99% confidence interval for the students' mean iq score? answers given below: 118.87−121.13 107.12−132.88 125−135 115−125

Answers

Answer with explanation:

Total Sample Size = 4,500 Students

Sample Chosen(n) = 130 students

Mean IQ of the Sample, $\bar{X} = 120$

Standard Deviation, $\sigma=5$

To Calculate 99% confidence interval for the students' mean IQ score, we will calculate,

$Z_(99 percent)=2.58$

Formula for Confidence Interval

$=\bar{X} \pm Z_(99 percent)* (\sigma)/(√(n))\n\n=120 \pm 2.58 * (5)/(√(130))\n\n=120 \pm (12.9)/(11.401)\n\n =120 \pm 1.1314\n\n=120 \pm 1.13$

The Value of Confidence interval will lie between

⇒ 120 - 1.13 to 120 +1.13

⇒118.87 to 121.13

Option A: 118.87−121.13

$C.I.=120 \pm z_( \alpha /2) ( \sigma )/( √(n) ) \n =120 \pm 2.58 * (5)/( √(130) ) \n =120 \pm 1.13 \n =118.87 - 121.13$

25d-16=4d+26
whats d?

Answers

Like terms are when the variable you have are the same. In this case it is x. Therefore, when you have like terms, you should add, or subtract your like terms.

(note: When you move one thing to the other side of the equation, make sure to do the opposite of the sign. i.e. if it is +26 when you move to the other side it will be -26).

25d-16=4d+26
25d-16+16=4d+26+16
25d=4d+26+16
25d-4d=4d-4d+26+16
25d-4d=26+16
21d=42
this is the same as:
21*d=42
the opposite of multiply is divide so when we move the 21 it has to be divide
21/21*d=42/21
d=2

For this question you should first add -4d on both sides of the equation and then add +16 on both sides:
25d - 4d = 26+16
21d = 42
d = 42/21
d = 2 :)))

The solution for $ x $ of the equation $ 8 e^{x}-1=0 $ is

Answers

Answer:

Step-by-step explanation:

The equation $8e^x - 1 = 0$ can be solved to find the value of $x$.

To solve for $x$, we need to isolate the exponential term, $e^x$.

Here are the steps to solve the equation:

1. Add 1 to both sides of the equation to isolate the exponential term:

$8e^x = 1$

2. Divide both sides of the equation by 8:

$\frac{{8e^x}}{8} = \frac{1}{8}$

3. Simplify:

$e^x = \frac{1}{8}$

4. To solve for $x$, we can take the natural logarithm (ln) of both sides of the equation:

$\ln(e^x) = \ln\left(\frac{1}{8}\right)$

5. Since $\ln(e^x)$ and $e^x$ are inverse functions, they cancel each other out:

$x = \ln\left(\frac{1}{8}\right)$

6. Use the properties of logarithms to simplify further:

$x = \ln(1) - \ln(8)$

7. Simplify:

$x = -\ln(8)$

Therefore, the solution for $x$ in the equation $8e^x - 1 = 0$ is $x = -\ln(8)$.
