here a subtraction problem that has been solved incorrectly 21-9=11 what answer I got b 11+9=20
Answer:
I put the answer on your copy of this question. However, I can at least put the equation here.
You are correct in this case.
11 + 9 = 20 - 9 = 11
11 plus 9 equals 20, 20 minus 9 equals 11 (correct statement)
Is the answer a, b, c, or d?? Please help!!
I believe the answer would be C, tell me if I'm wrong.
A bag contains 2 red marbles, 6 blue marbles and 7 green marbles. If two marbles are drawn out of the bag, what is the probability, to the nearest 100oth, that both marbles drawn will be red?
Answer:
0.01 (nearest hundredth)
Step-by-step explanation:
[tex]\mathsf{probability=\dfrac{number \ of \ favorable \ outcomes}{number \ of \ total \ outcomes}}[/tex]
Total number of marbles (total outcomes) = 2 + 6 + 7 = 15
⇒ Probability of the first marble being red = [tex]\dfrac{2}{15}[/tex]
As there is no replacement, the total number marbles is now 15 and there is only 1 red marble left.
⇒ Probability of the second marble being red = [tex]\dfrac{1}{14}[/tex]
So the probability of the 1st and 2nd marble being red is:
[tex]\dfrac{2}{15}\times \dfrac{1}{14} = \dfrac{1}{105}[/tex] = 0.01 (nearest hundredth)

Answer:
Question 1 read explanation. Question 2 it's c= 5. Question 3 it's 5 miles. Question4 it's
Step-by-step explanation:
For question 1 it's just asking you to make a right triangle with the segment as the hypotenuse. To do that make a dot on (5,1) and draw the triangle. A hypotenuse is the longest side of a right triangle, opposite the right angle.
For question 2 you just get the units of the triangle. The hypotenuse is always c (the segment). However, it's difficult to find c by just looking at the graph. That's why you plug in the other sides a = 3 and b = 4 (doesn't matter which way) to find c. So, you plug in 3^2 + 4^2 = c^2. This will give 9 + 16 = c^2, which is 25 = c^2. We need c not c^2! That means we square 25 to get 5. c = 5!
For question 3, you use the answer from question 2 I believe, so it's 5 miles.
For question 4, it's the same as question 1 so if it helps you make a visual on paper. Draw those two dots and to make a right triangle you'll also need the point (1,1). Find the units 8^2 + 10^2 = c^2. c = 2root41.
Describe two different ways that you could find the product 3x990
990 = 1000 - 10
so 3 x 990 = 3 x (1000 - 10) = 3 x 1000 + 3 x (-10) = 3000 - 30 = 2970
and
990 = 900 + 90
so 3 x 990 = 3 x (900 + 90) = 3 x 900 + 3 x 90 = 2700 + 270 = 2970

An analyst wants to determine if there is any difference in the amount of time teenagers play video games between two years. To do this, he takes a random sample of teenagers and gathers the average time they spent playing video games the previous year and compares it to the average time they spent playing video games this year. Suppose that data were collected for a random sample of 15 teenagers, where each difference is calculated by subtracting the time spent playing video games this year from the time spent playing video games last year. Assume that the times are normally distributed. What is/are the critical value(s) of the t-test statistic for this hypothesis test, where α=0.10? Use a comma and a space to separate answers as needed.
Answer:
The critical value is [tex]t_{\frac{0.10}{2} , 14 } =[ - 1.761,1.761][/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 15
The level of significance is [tex]\alpha = 0.10[/tex]
The null hypothesis is [tex]H_o : \mu _1 = \mu_2[/tex]
The alternative hypothesis is [tex]H_a : \mu_1 \ne \mu_2[/tex]
Here [tex]\mu_1[/tex] is average time for previous year
[tex]\mu_2[/tex] is the average time for current year
Generally the degree of freedom is mathematically represented as
[tex]df = n -1[/tex]
=> [tex]df = 15 - 1[/tex]
=> [tex]df = 14[/tex]
Generally from the student t distribution table the critical value for [tex]\frac{\alpha }{2}[/tex] at a degree of freedom of [tex]df = 14[/tex] for a two tailed test is
[tex]t_{\frac{0.10}{2} , 14 } =[ - 1.761,1.761][/tex]

Damita says the equations 0.8x - 0.8 = 1.6 and 4/5 ( x - 1 ) = 1 (3/5) are the same. How can she show this without solving the equations?
To show that the equations are the same, we need to rewrite one of the equations as an equivalent equation of the second
Damita's claim is true
How to show the equations are the sameThe equations are given as:
0.8x - 0.8 = 1.6
4/5 ( x - 1 ) = 1 (3/5)
We need to rewrite one of the equations, as follows:
4/5 ( x - 1 ) = 1 (3/5)
Express as decimal
0.8 ( x - 1 ) = 1 + 0.6
Open the brackets
0.8x - 0.8 = 1.6
Now we have:
0.8x - 0.8 = 1.6 (the first equation) and 0.8x - 0.8 = 1.6 (the equivalent of the second equation)
The above shows that both equations are the same

The mean of 30 test scores was 92. The range of scores was 10.
Answer:
First option.
Step-by-step explanation:
The mean of a set of data is all the data added together divided by the total numbers in that data set. So not only do you have to add an additional 45 to the data set, but you also have to divide the total of all the test scores by the total number of test takers which is now 31.
The range of a set of data is rearranging the data set smallest to largest and then subtracting the smallest from the largest value in the data set. Since the mean is 10 it's a small chance that 45 is either smallest or the largest of the set of data. We don't know the median, or the mode of the data set, nor does the question give us the other 30 test scores so it's between the range and the mean.
The most affected with the inclusion of the additional students test score would be the first option or the "mean."
Hope this helps.
You and your friends order a meal for $116.29. How much tip should you leave if you want to leave a 12% tip?
Answer:
$13.95
Step-by-step explanation:
$166.29 ×12/100
=$13.95 will be the tip.
Answer:
$13.95
Step-by-step explanation:
Convert the 12% to an actual number that can be used in a calculator. For percents, this is done by dividing the percent (in this case 12%) by 100%.So, the conversational term "12%" becomes 12% / 100% = 0.12 in terms of a real mathematical number. Then you need to find out what 12% of your $116.29 meal cost is.This is always done by multiplying 0.12 by $116.29, or 0.12 x $116.29=$13.95.
Consider the sequence 10, 2..
Create a totally different sequence that begins 10,2, ... For your sequence, write the next four terms and an equation for t(n). Cannot be arithmetic or geometric.
Answer: see below
Step-by-step explanation:
1) 10, 2, 1.2, 1.12, 1.112, 1.1112
[tex]t_n=\dfrac{t_{n-1}}{10}+1[/tex]
t₁ = 10
t₂ = 10/10 + 1 = 2
t₃ = 2/10 + 1 = 1.2
t₄ = 1.2/10 + 1 = 1.12
t₅ = 1.12/10 + 1 = 1.112
t₆ = 1.112/10 + 1 = 1.1112
2) 10, 2, -2, -4, -5, -5.5, ...
[tex]t_n=\dfrac{t_{n-1}}{2}-3[/tex]
t₁ = 10
t₂ = 10/2 - 3 = 2
t₃ = 2/2 - 3 = -2
t₄ = -2/2 - 3 = -4
t₅ = -4/2 - 3 = -5
t₆ = -5/2 - 3 = -5.5
