Answer:
x = -10
Step-by-step explanation
5x+7(-3x-14)=162
First, 5x -21x - 98 = 162
Then, combine like-terms, -26x - 98 = 162
After that, add 98 to 162, and you'll end up with 260.
Finally, you'll wanna divide the -26x to the 162.
You'll end up with x = -10
Answer:
4
Step-by-step explanation:
The given polynomial is :
p(x) = -2a⁴+8a³-9a
We need to find the degree of the polynomial.
Degree of the polynomial = degree is the value of the greatest exponent.
Here, the maximum value of the exponent is 4 in -2a⁴.
It means,
Degree of the polynomial = 4

Answer:
1.63% probability that the 10 selected include include all the best 5 engineers in the group of 20
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the engineers are selected is not important, so the combinations formula is used to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
Desired outcomes:
10 engineers selected from a set of 20.
5 best, from a set of 5.
Other 5, from a set of 20-5 = 15.
Totao outcomes:
10 engineers selected from a set of 20.
Probability:
1.63% probability that the 10 selected include include all the best 5 engineers in the group of 20
Answer:
y = 18
Step-by-step explanation:
Since the triangles are similar, the corresponding sides are in proportion, that is
= , substitute values
= ( cross- multiply )
14y = 252 ( divide both sides by 14 )
y = 18
