find the value of x in each figure

PLEASE DONT GIVE ME A LINK

Answers

Answer 1

Answer:

x = 24

Step-by-step explanation:

3X +5 +2x-4 +2x +11 = 180

7x +12 = 180

7x = 180 - 12

7x = 168

7x/7 = 168/7

x =24

michaela spent $33 on 3 rose bushes and 3 pots of ivy. totsakan spent $92 on 12 rose bushes and 4 pots of ivy. find the cost of one rose bush and the cost of one pot of ivy

Answers

Answer:

One rose bush costs $6

One pot of ivy costs $5

Step-by-step explanation:

Set up an equation:

Variable x = cost of rose bushes

Variable y = cost of pots of ivy

3x + 3y = 33

12x + 4y = 92

I will use substitution to first solve for x:

3y = 33 - 3x

Divide both sides by 3

y = 11 - x

Substitute y value for 11 - x:

12x + 4(11 - x) = 92

Use distributive property

12x + 44 - 4x = 92

Combine like terms

8x + 44 = 92

8x = 48

Divide both sides by 8

x = 6

Solve for y by plugging in 6 for the x value:

3(6) + 3y = 33

18 + 3y = 33

3y = 15

Divide both sides by 3

y = 5

Check work:

3(6) + 3(5) = 33

18 + 15 = 33

33 = 33

Correct

A newspaper article indicated that 43 percent of cars with black seats are white, 46 percent of cars with black seats are blue, 7 percent of cars with black seats are red, and 4 percent of cars with black seats are black. A test was conducted to investigate whether the color of cars with black seats was consistent with the newspaper article. A random sample of cars of these colors was selected, and the value of the chi-square test statistic was x = 8.2. Which of the following represents the p-value for the test?
A) P(x2 ≥ 8.2) = 0.08
B) P(x2 ≥ 8.2) = 0.04
C) P(x2 ≤ 8.2) = 0.96
D) P (x2 = 8.2) = 0.00
E) The p-value cannot be calculated because the sample size is not given.

Answers

Answer:

C) P (X2 ≤ 8.2) = 0.96

Step-by-step explanation:

P value for the test is the probability of obtaining results that have been observed in the null hypothesis statement. A very small value of p indicates that there is unlikely chance of null hypothesis being true which means that we cannot accept null hypothesis based on the small p value.

Answer:

P(χ2≥8.2)=0.04

What is the are of the arrow?

Answers

Answer:

Step-by-step explanation:

First you need to find the area of the square. You have to multiply 4x10 which is 40. So now you have to find the area of the triangle. To do that you have to use this equation base x Height/2. Basically 6 times 3.5 is 21/2 so its 10.5. Since you have 2 triangles you can just multiply by 2 which is 42 so 42 + 42 is 84

after months of negotiations,jabus annual salary was increased by 6,5percent to R330 000. determine his previous monthly salary and the monthly increase he will be getting

Answers

Answer:

previous monthly salary is R 308,550 and increment is R 21,450

Step-by-step explanation:

Let the previous monthly salary be x

Current salary = R 330,000

Percent increase = 6,5%

Increase = 6.5% * 330,000

Increase = 0.065 * 330,000

Increase = Rs21,450

Previous salary = 330,000 - 21,450

Previous salary = 308,550

Hence previous monthly salary is R 308,550 and increment is R 21,450

Freshman, sophomore, junior, and senior students at a high school will be surveyed regarding a potential increase in the extracurricular student activities fee. There are three possible responses to the survey question - agree with the increase, do not agree with the increase, or no opinion. A chi-square test will be conducted to determine whether the response to this question is independent of the class in which the student is a member. How many degrees of freedom should the chi-square test have

Answers

Answer:

The degrees of freedom is 6 for the chi square independence test.

Step-by-step explanation:

This is test hypothesis of independence. The test statistic under H0 is

χ²= ∑ (O - E)²/ E

where O is the observed and E is the expected frequency

which has an approximate chi square distribution with ( r-1) (c-1) degrees of freedom, where r= rows and c= columns.

Here there are 4 rows and 3 columns

Hence the degrees of freedom will be

( 4-1) ( 3-1)= 3*2= 6

37. The sum of two numbers is 86. The larger number is nine less than four times the smaller number. Find both numbers.

Answers

The larger number is 67 while the smaller number will be 19 for the given condition.

What is a number system?

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use frequently.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

As per the given,

Suppose the larger number is x while the smaller number is y.

Sum will be as x + y = 86

The larger number is nine less than four times the smaller number.

x = 4y - 9

By substitution,

4y - 9 + y = 86

5y = 95

y = 19

x = 86 - 19 = 67

Hence "For the specified condition, the greater number is 67 and the smaller number is 19".

Answer: 18

Explanation: 18 times 2.5 is 45. 45 +18=63

Answer:

the answer would be 25 because to get the answer you would take 63 and divide it by 2.5 and you will get 25.2 then rounding it to the nearest 10th would be 25

then after you get 25 you would put it into the equation 2.5(x) = 63 which would be 2.5(25)=63. that it y 25 would be the correct answer.

Only the healthy foods we eat provideenergy to our bodytruefalse When you use tobacco products, nicotine is quickly absorbed into your bloodstream. Within 10 seconds of entering your body, the nicotine reaches your brain and causes the brain to release adrenaline, creating a buzz of pleasure and energy. The buzz fades quickly though, and leaves you feeling tired, a little down, and wanting the buzz again. This feeling is what makes you light up the next cigarette. Since your body is able to build up a high tolerance to nicotine, youll need to smoke more and more This up and down cycle repeats over and over, leading to addiction. Addiction keeps people smoking even when they want to quit. Research suggests that children and teens may be especially sensitive to nicotine, making it easier for them to become addicted. The younger smokers are when they start, the more likely they are to become addicted. In fact, about three out of four high school smokers will become adult smokers. Nicotine Addiction and Your Health Which effects of nicotine use do most users experience? Check all that apply. Nicotine affects the pleasure centers of the brain, making it addictive. Teens who smoke are less likely to smoke as adults. People have to increase their nicotine use over time to receive the same effects. People who want to quit are generally able to do so. Stopping use leads to a tired feeling.
