Answer:

**Answer:**

A. $4397.9

**Step-by-step explanation:**

**We are given that Kendra sold 200 shares and that the price per share was $22.1**

**This means that:**

**Total value = 200 * 22.1 = $4420**

**Now, we know that the broker charged 0.5% commission on the total value**

**This means that:**

**Broker's charge = 0.5% * 4420 = 0.005 * 4420 = $22.1**

**Therefore,**

**Kendra's return = Total value - broker's charge**

**Kendra's return = 4420 - 22.1 = $4397.9**

**Hope this helps :)**

**Answer:**

other x values are -5,-4

**Step-by-step explanation:**

f(x)=0 for x=−6

Apply synthetic division to get the quotient . using that we find other two values of x

-6 1 15 74 120

0 -6 - 54 -120

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

1 9 20 0

the quotient is

now factor the left hand side, product is 20 and sum is 9

So other x values are -5,-4

**Answer:**

$27.60

**Step-by-step explanation:**

23×1.2=27.60 is the answer

To calculate a 20% tip on a $23 check, multiply $23 by 0.20 to get the tip amount of $4.60. The total amount you should pay, including the tip, is $27.60.

To calculate a 20% tip on a $23 check, you need to multiply the total bill amount by the percentage of the tip, expressed as a decimal. 20% as a decimal is 0.20. So you simply multiply $23 by 0.20 to get the tip amount.

Here is the math:

- Start with the total bill amount:
**$23**. - Convert the tip percentage into a decimal: 20% =
**0.20**. - Multiply the total bill amount by the tip percentage in decimal form: $23 x 0.20 =
**$4.60**. - Add the tip amount to the total bill amount: $23 + $4.60 = $
**27.60**.

So, if you want to leave a 20% tip on a $23 check, you should pay a total of $27.60.

#SPJ3

**Answer:**

63 tons

**Step-by-step explanation:**

The problem statement asks for the tons of hay removed from the first pit. It is convenient to let a variable (x) represent that amount. This is said to be 3 times the amount removed from the second pit, so that amount must be x/3.

The amount remaining in the first pit is 90-x.

The amount remaining in the second pit is 75 -x/3.

Since the first pit remaining amount is half the second pit remaining amount, we can write the equation ...

... 90 -x = (1/2)(75 -x/3)

... 180 -2x = 75 -x/3 . . . . multiply by 2

... 105 - 2x = -x/3 . . . . . . subtract 75

... 315 -6x = -x . . . . . . . . multiply by 3

... 315 = 5x . . . . . . . . . . . add 6x

... 63 = x . . . . . . . . . . . . . divide by 5

**63 tons of hay were taken from the first pit.**

_____

*Check*

After removing 63 tons from the first pit, there are 27 tons remaining. After removing 63/3 = 21 tons from the second pit, there are 54 tons remaining. 27 is half of 54, so the answer checks OK.

**Answer:**

**We conclude that the new teaching method does not negatively affects reading comprehension scores.**

**Step-by-step explanation:**

We are given that an educational psychologist wants to test whether a new teaching method negatively affects reading comprehension scores.

She randomly selects 30 6th grade students that were taught under the new teaching method and finds that their scores on a standardized reading comprehension test have a mean equal to 118.8 with a variance equal to 37.2.

Scores on the standardized test in the general population of 6th graders are distributed approximately normally with a mean equal to 119.8.

*Let ** = mean scores on a standardized reading comprehension test.*

So, **Null Hypothesis**, : 119.8 {means that the new teaching method does not negatively affects reading comprehension scores}

**Alternate Hypothesis,** : < 119.8 {means that the new teaching method negatively affects reading comprehension scores}

The test statistics that would be used here __ One-sample t test statistics__ as we don't know about the population standard deviation;

T.S. = ~

where, = sample mean test score = 118.8

s = sample standard deviation = = 6.1

n = sample of 6th grade students = 30

So, __test statistics__ = ~

= -0.898

The value of t test statistics is -0.898.

Since, in the question we are not given with the level of significance so we assume it to be 5%. **Now, at 5% significance level the t table gives critical value of -1.699 for left-tailed test.**

Since our test statistic is more than the critical value of t as -0.898 > -1.699, so we have insufficient evidence to reject our null hypothesis as it will not fall in the rejection region due to which __we fail to reject our null hypothesis__.

**Therefore, we conclude that the new teaching method does not negatively affects reading comprehension scores.**

**Answer:**

20%

**Step-by-step explanation:**

The reason it is 20% is due to the fact that if you put it in a form showing 250/250 = 100/100 and put another proportional rate underneath it showing 200/250 = x/100, you would have to multiply the numerator of the fraction on the left by the denominator of the fraction on the right to get 20000. Now you divide 250 from 20000 and get x for 80, resulting in 80/100 or 80%. All you have to do now is subtract 100-80, which equals 20, resulting in 20%.

Hope that helps!! It's my first time in answering so, ya. ;D goodluck!

it’s 20% like the person said on top give that person brainliest lol
