I haven’t done math in forever, do you want us to simplify it? Bc it would be 2x+8=-16=4x+6 but I’m not sure

A single 6-sided die is rolled twice. The set of 36 equally likely outcomes is {(1,1), (1,2), (1,3), (1,4), left parenthesis

Dennis_Churaev [7]

Answer:

The probability of getting two numbers whose sum is greater than 9 and less than 13 is $\frac{1}{6}$

Step-by-step explanation:

Given : A single 6-sided die is rolled twice.

To find : The probability of getting two numbers whose sum is greater than 9 and less than 13 ?

Solution :

The set of 36 equally likely outcomes,

1 2 3 4 5 6

1 (1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6)

2 (2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6)

3 (3, 1) (3, 2) (3, 3) (3, 4) (3, 5) (3, 6)

4 (4, 1) (4, 2) (4, 3) (4, 4) (4, 5) (4, 6)

5 (5, 1) (5, 2) (5, 3) (5, 4) (5, 5) (5, 6)

6 (6, 1) (6, 2) (6, 3) (6, 4) (6, 5) (6, 6)

Getting two numbers whose sum is greater than 9 and less than 13

The favorable outcome is (4,6),(5,5),(5,6),(6, 4),(6, 5),(6, 6) = 6

The probability is given by,

$\text{Probability}=\frac{\text{Favorable Outcome}}{\text{Total Outcome}}$

$\text{Probability}=\frac{6}{36}$

$\text{Probability}=\frac{1}{6}$

Therefore, The probability of getting two numbers whose sum is greater than 9 and less than 13 is $\frac{1}{6}$

Lauren bought a rectangular box that is 6 inches long, 10 inches wide and 4 inches high. she wants to cover it in fabric. the fa

First you'll need to find the area of each side and then add those areas together. 2(6x10)+2(4x6)+2(4x10)= 120+48+80=248
then you multiply the total area by .25 and get 62. It will cost $62.

Describe the relationship between the number of "at bats" and the number of hits using the data in the scatter plot.

butalik [34]

Answer: A.) For these data, as the number of at bats increases, the number of hits tend to increase.

This is because the points seem to trend upward as we move from left to right. This makes sense because the more attempts you get, the more hits you're expected to get.

Assume that someone has a batting average of 0.300; this means that if they got 1000 attempts, then we expect about 0.300*1000 = 300 hits. Now if they got 2000 at bats this time, then we expect about 0.300*2000 = 600 hits.

Of course things won't fit this perfectly since everything in life has random statistical error, but this gives a good idea of the upward trending data. The two variables (at bats and hits) are strongly related. We can say the variables have strong positive correlation.

Subtract: 8 – 4 1∕2 .

Otrada [13]

Always follow the rules of BOMDAS. (If you don't know them or maybe learned differently tell me).
Firstly multiply 4(1/2) and then substract
8 - 4(1/2)
8 - 2
6
Hope this helps :).
