Answer:
B, x≥2
Step-by-step explanation:
54 - 10x ≤ 20 + 7x - subtract 20
34 - 10x ≤ 7x - add 10x to 7x
34 ≤ 17x - divide 34 by 7
2 ≤ x - flip the equation - x ≥ 2
Hope this is helpful!
Answer:
B) rose bush: $8, pot of ivy: $11
Step-by-step explanation:
12(8) + 13(11) = 239
remove parentheses: (a) = a
= 12 * 8 + 13 * 11
multiply the numbers: 12 * 8 = 96
= 96 + 13 * 11
multiply the numbers: 13 * 11 = 143
= 96 + 143
add the numbers: 96 + 143 = 239
= 239
Answer:
0.0105
Step-by-step explanation:
given that 30% of all houses need a paint job. Also, 15% of all houses need both a paint job and a new roof. Further, 7% of all houses that need a new roof also need new windows.
If total houses are 100, then 30 require a paint along. 15 require both paint and new roof.
Out of 15 houses which require new roof 7% need new windows
i.e. no of houses which need new windows = 
If there are total 100 houses, 1.05 houses require a new window
So probability that a randomly selectede house needs a new window
= 0.0105
Answer:
True
Step-by-step explanation:
The null space of matrix is set of all solutions to matrix. The linearly independent vectors forms subset which are spanned and forms the null space. The null space of vector can be found by reducing its echelon. The non zero rows formed are the null spaces of matrix.
It would show the average time spent on the homework.
And the average distance between the mean and the lowest and highest numbers in the data.
