1. Which store had the highest demand both before and after the price increase?

230 is the  value of the company in 2018.

Option (B) is correct.

To find 230 represent in the function.

science that deals with the addition, subtraction, multiplication, and division of numbers.

It is given that:

The equation of a exponential growth function is equal to

[tex]V(t)=a(1+r)^{t}[/tex]

where,

V(t) is the value of the company

t is the number of years after 2018

a is the initial value or y-intercept

r is the rate of change

Put the value,

a=230

1+r=1.12

r=1.12-1=0.12

r=12%

so 230 is the value of the company when the value of t is equal to zero.

Remember that t is the number of years since 2018

Therefore ,230 is the  value of the company in 2018.

Answer:

a.

Step-by-step explanation:

A p-value less than 0.05 (typically ≤ 0.05) is statistically significant. It indicates strong evidence against the null hypothesis, as there is less than a 5% probability the null is correct (and the results are random). Therefore, we reject the null hypothesis, and accept the alternative hypothesis.

------------------------

First question:

The first question involves the test of an hypothesis.

Tests have significance levels, which normally are either 0.01, 0.05 or 0.1. If the p-value is less than the significance level, the results are significant, while if they are more, the results are not significant.

In this question, the p-value is 0.45, which is considerably more than any significance level, meaning that the results are nowhere near to being statistically significant, and the correct option is:

a. The results are nowhere near to being statistically significant.

Second question:

The order in which the people are chosen is important, as the first and second person chosen have different roles, and thus, the permutations formula is used.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

In this problem, there are 2 people from a set of 10, so:

To round 721295.198715 to the nearest ten, we increase the tens place from 9 to 0 due to the ones place being 5, resulting in 721300.

To round the number 721295.198715 to the nearest ten, we should look at the digit in the ones place, which is 5. Since the ones digit is 5 or greater, we need to round up the tens place.

Therefore, the tens digit increases by one from 9 to 0, and all digits to the right of the tens place become zero.

Thus, 721295 rounds up to 721300 when rounded to the nearest ten.

Note that we ignore the decimal and its subsequent numbers because they do not influence the rounding of a number to the nearest ten.

Step-by-step explanation:

Two secants drawn from an external point to the circle.

The (outside ) × (whole) of one secant is equal to the (outside) × (whole) of the other secant, that is

(x + 2)(x + 2 + 2x - 8) = (x + 1)(x + 1 + 2x - 5)

(x + 2)(3x - 6) = (x + 1)(3x - 4) ← expand both sides using FOIL

3x² - 12 = 3x² - x - 4  ( subtract 3x² - x - 4 from both sides )

x - 8 = 0 ( add 8 to both sides )

x = 8

The number of bananas that Emily bought was 6 and the number of peaches that Emily bought was 8

Step-by-step explanation:

The complete question is

Emily and her children went into a grocery store and she bought $20.80 worth of bananas and peaches. Each banana costs $0.80 and each peach costs $2. She bought  a total of 14 peaches and bananas altogether. Determine the number of peaches and the  number of bananas that Emily bought

Let

x ----> the number of bananas that Emily bought

y ----> the number of peaches that Emily bought

we know that

She bought  a total of 14 bananas and peaches altogether

so

Answer:

Step-by-step explanation:

The 21st term of the given geometric sequence can be found by using the formula for the n-th term of a geometric sequence: a_n = a_1 * r^(n-1). In this case, it is 112.5 * 2^(21-1).

In a geometric sequence, each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio. In this case, 225 divided by 112.5 gives us the common ratio of 2. Therefore, to find the 21st term of the given geometric sequence, we use the formula: a_n = a_1 * r^(n-1). Here, a_n is the n-th term, a_1 is the first term, r is the common ratio and n is the term which we want to find.

So, substituting the given values into the formula, a_21 = 112.5 * 2^(21-1). Calculate this and you'll have the 21st term of the geometric sequence.

Answer:

$165.50 dollars

Step-by-step explanation:

$993 / 6 = $165.50

Lula will need to pay $165.50 each month for 6 months to pay off her $993 furniture purchase without interest.

Lula purchased furniture on her credit card and plans to make payments over a period of 6 months with no interest charged. To calculate the monthly payment amount, you would divide the total cost of the furniture by the number of months over which she plans to pay.

The formula to find out the monthly payment is:

Monthly Payment = Total Cost / Number of Months

So for Lula, it looks like this:

Monthly Payment = $993 / 6

Monthly Payment = $165.50

Therefore, if Lula pays $165.50 each month, she will have the furniture paid off in 6 months without incurring any interest.

Answer:

a) 675 000

b) 685 000

Step-by-step explanation:

The population of a town is 680 000 correct to the nearest 10 000.

a) To find it lower bound, we level of accuracy by 2 and then subtract from 680 000

The lower bound is:

680 000-5000=675,000

Therefore the least possible population of the town is 675 000

b) We repeat the same process to find the upper bound

680 000+5000=685,000

To find the equivalent expression for the given expression.

[tex]\sqrt[5]{(n+4)^{3}}[/tex]

Using radical rule: [tex]$\sqrt[m]{a}=a^{\frac{1}{m}}[/tex]

      [tex]$=\left((n+4)^{3}\right)^{\frac{1}{5}}[/tex]

Using exponent rule: [tex]$\left(a^{b}\right)^{c}=a^{b c}[/tex]

[tex]B) \frac{DE }{EA} =\frac{CB}{AC}[/tex]

Step-by-step explanation:

If ant two given triangles are SIMILAR, then they have equal corresponding angles and their corresponding sides are PROPORTIONAL.

For example: if Δ ABC ≈ Δ PQR, then

∠A  = ∠P  , ∠B  = ∠Q  and ∠C  = ∠R

and [tex]\frac{AB}{PQ} = \frac{BC}{QR} = \frac{AC}{PR}[/tex]

Now, here given:  Δ ADE ≈ Δ ABC

Then by the SIMILAR postulate their corresponding angles are equal and their corresponding sides are Proportional.

[tex]\implies \frac{AD}{AB} = \frac{DE}{BC} = \frac{AE}{AC}[/tex]    ............. (1)

Consider from above:

 [tex]\frac{DE}{BC} = \frac{AE}{AC}\\\implies \frac{DE}{AE} = \frac{BC}{AC}[/tex] ............. (2)

Here, the given options are:

[tex]A) \frac{EA }{DE} =\frac{CB}{AC}[/tex]     FALSE

[tex]B) \frac{DE }{EA} =\frac{CB}{AC}[/tex]   TRUE    (from 2)

Answer:

c) 4

Step-by-step explanation:

The sum of two numbers is 14. The larger number minus three times the lesser number is -2

To solve this question, we need to write the statement mathematically;

Let the two numbers be x and y

"The sum of two numbers is 14" can be mathematically written as x+y = 14

and

"The larger number minus three times the lesser number is -2" can be mathematically written as x -  3y  = -2

x + y = 14  ------------------(1)

x - 3y= -2 -------------------(2)

Subtract equation (2) from equation (1)

[x - x = 0          y - (-3y)=4y     14-(-2)=16]

4y  = 16

To get the value of y divide both-side of the equation by 4

4y/4 = 16/4

y  =   4

Substitute y=4 into equation (1)

x + y =14

x +4 =14

Subtract 4 from both-side of the equation

x + 4 -4  = 10]-4

x = 10

x=10 and y =4

Therefore the lesser number is 4

Step-by-step explanation:

Ok so a number multiplied by 4 equal  a number multiplied by 8.

Both numbers can't have the same variable because if they had the same varable that means they are the same number which in that case means Marcy is wrong but we know she is right because Mr.Kim said so.

let's plug in numbers. If they had the same variable it would be:-4x=8x

                                                                                         let x=2,    4(2)=8(2)

                                                                                                           8=16 not true

if the variables were not the same:-4x=8y

                                   let x=4

                                   let y=2          4(4)=8(2)

                                                          16=16 true
