Ray is x years old. His brother Ron is y years older than Ray.
How old will Ron be in 2 years?
Answer:
Ray is x years old.
Ron is x+y years old.
In 2 years, Ron will be two years older than now, so x+y+2 years old.
Step-by-step explanation:
Enjoy!
Answer:
Ray is x years old.
Ron is x + y years old.
In 2 years, Ron will be two years older than now, so
x + y + 2 years old.
Since their ages are variables, you should only have 1 clear digit which is 2. Due to the information given
The maximum acceptable level of a certain toxic chemical in vegetables has been set at 0.4
parts per million (ppm). A consumer health group measured the level of the chemical in a
random sample of tomatoes obtained from one producer.
The levels, in ppm, are shown below.
0.31 0.47 0.19 0.72 0.56
0.91 0.29 0.83 0.49 0.28
0.31 0.46 0.25 0.34 0.17
0.58 0.19 0.26 0.47 0.81
Does the data provide sufficient evidence to support the claim that the mean level of the
chemical in tomatoes from this producer is greater than the recommended level of 0.4 ppm?
Use a 0.05 significance level to test the claim that these sample levels come from a population
with a mean greater than 0.4 ppm. Use the P-value method of testing hypotheses. Assume that
the standard deviation of levels of the chemical in all such tomatoes is 0.21 ppm.
Choose the correct null and alternative hypotheses associated with this experiment.
Null hypothesis (H0): The mean level of the chemical in tomatoes from this producer is equal to or less than the recommended level of 0.4 ppm.
Given that, the maximum acceptable level of a certain toxic chemical in vegetables has been set at 0.4 parts per million (ppm).
Alternative hypothesis (H1): The mean level of the chemical in tomatoes from this producer is greater than the recommended level of 0.4 ppm.
To test the claim, we will use a one-tailed hypothesis test with a significance level of 0.05. The test statistic is calculated by subtracting the mean of the sample from the mean of the population, and dividing the result by the standard deviation of the population.
Test statistic = (Sample mean - Population mean) / Standard deviation of population
Test statistic = (0.465 - 0.4) / 0.21
Test statistic = 2.38
Since the test statistic is positive, we can reject the null hypothesis. The P-value for this test statistic is 0.0095, which is less than 0.05.
Therefore, the data provides sufficient evidence to support the claim that the mean level of the chemical in tomatoes from this producer is greater than the recommended level of 0.4 ppm.

Step-by-step explanation:
17 + 19 = 36 x 5 = 180
Answer:
5 hours
Step-by-step explanation:
so since it al together you add 17+19 which equals 36. after that you divide 180 by 36 which equals 5. to recheck this I multipled 17 by 5 and 19 by 5. equaling 85 plus 95 equals 180 meaning it is 5

[tex](2c+a+3b)(2c-a-3b)[/tex]
Step-by-step explanation:
Given expression: [tex]4c^2-a^2-6ab-9b^2[/tex]
Factor [tex]-a^2-6ab-9b^2[/tex]
[tex]\implies -(a^2+6ab+9b^2)[/tex]
[tex]\implies -(a+3b)(a+3b)[/tex]
[tex]\implies -(a+3b)^2[/tex]
Factor [tex]4c^2[/tex]

Therefore,
[tex](2c)^2-(a+3b)^2[/tex]
Difference of Two Squares: [tex]x^2-y^2=(x+y)(x-y)[/tex]
[tex]x^2=(2c)^2\implies x=2c[/tex]
[tex]y^2=(a+3b)^2 \implies y=a+3b[/tex]
Therefore,

[tex]\implies (2c+a+3b)(2c-a-3b)[/tex]
Answer:
(2c - a + 3b)(2c + a + 3b)
Step-by-step explanation:
4c² - a² - 6ab - 9b²
= 4c² - (a² + 6ab + 9b²) ← the terms in the parenthesiis are a perfect square )
= 4c² - (a + 3b)² ← this is a difference of squares which factors in general as
a² - b² = (a - b)(a + b) , then
= (2c)² - (a + 3b)²
= (2c - (a + 3b) )(2c + (a + 3b) )
= (2c - a - 3b)(2c + a + 3b)

Stephanie has $42,750 in student loans at a 6% compound interest
rate. If she decides to defer payment on the loan for two years, how
much additional interest will be added to the loan at the end of the
two-year deferment?
Answer:
You first take the annual interest rate on your loan and divide it by 365 to determine the amount of interest that accrues on a daily basis. Say you owe $10,000 on a loan with 5% annual interest. You'd divide that rate by 365 (0.05 ÷ 365) to arrive at a daily interest rate of 0.000137.

Answer:
x is equal to 30
<ABC is equal to 100°
<DBC is equal to 80°
Step-by-step explanation:
3x +10 +2x +20 =180
5x = 180 - 10- 20
5x = 150, divide both sides by 5
x is equal to 30
<ABC = 3x + 10 = 3 × 30 + 10 = 100°
<DBC = 180 - <ABC = 180 - 100 = 80°

Answer:
18. $5890
19. Mitsubishi Mirage
Step-by-step explanation:
The depreciated value can be found using an exponential relation. The decay rate here is given as 12.5%. The exponential function will have the form ...
y = a·b^x . . . . . a = initial value, b = decay factor = 1 - decay rate
__
18.The above equation will have a=15,000, representing the initial value of the car. It will have b=(1-0.125) = 0.875, the decay factor for the car's value. In the 7 years between your 18th and 25th birthdays, the car will have declined in value to ...
y = $15000·0.875^7 ≈ $5890.44
When you turn 25, the car will be worth about $5890.
__
19.We found three cars with a price under $15,000:
Nissan VersaChevrolet SparkMitsubishi MirageOf these, the Mirage gets the best mileage and has the most cargo space. (It also has the smallest engine.) The Spark has a continuously-variable transmission, not a 5-speed manual, so will be somewhat easier to drive. Its mileage is almost as good, but its range is about 10% less than that of the Mirage or Versa.
(Your curriculum may offer different choices. We cannot tell.)

suppose we want to choose 2 colors, without replacement, from the 5 colors red, blue, green, purple, and yellow.
Answer:
black and white should do right?
There are 20 ways to choose 2 colors without replacement, considering the order of choices as relevant, from the 5 colors: red, blue, green, purple, and yellow.
If the order of choices is relevant, it means we are dealing with permutations.
To calculate the number of ways to choose 2 colors from 5 colors without replacement and with order being relevant, we use the concept of permutations.
The number of permutations of choosing r items from n distinct items is given by the formula:
P(n, r) = n! / (n - r)!
where "n!" denotes the factorial of n, which is the product of all positive integers from 1 to n.
We want to choose 2 colors from 5 colors, so n = 5 (total colors) and r = 2 (colors to be chosen).
P(5, 2) = 5! / (5 - 2)!
= 5! / 3!
= (5 × 4 × 3 × 2 × 1) / (3 × 2 × 1)
= 120 / 6
= 20
Therefore, there are 20 different ways to choose 2 colors from the 5 colors (red, blue, green, purple, and yellow) without replacement and with the order being relevant.

Fully simplify your answer.
Answer: -[tex]\frac{1}{6}[/tex]
Step-by-step explanation:
To solve this question, I am going to first put the equation into slope-intercept form.
2x + 12y = -192
12y = -2x - 192
y = -[tex]\frac{2}{12}[/tex] - 16
y = -[tex]\frac{1}{6}[/tex] - 16
