In the diagram below of triangle PQS, S is the midpoint of PR and T is the midpoint of QR. If ST = 5x - 22, and PQ = 3x + 19, wh
at is the measurement of PQ?
1 answer:
Answer:
PQ = 46
Step-by-step explanation:
The midsegment ST is half the length of the third side PQ , that is
ST = PQ , so
5x - 22 = (3x + 19) ← multiply both sides by 2 to clear the fraction
10x - 44 = 3x + 19 ( subtract 3x from both sides )
7x - 44 = 19 ( add 44 to both sides )
7x = 63 ( divide both sides by 7 )
x = 9
Then
PQ = 3x + 19 = 3(9) + 19 = 27 + 19 = 46

Answer:
0.014
Step-by-step explanation:
The probability that the Islanders will win at least 6 out of seven is the probability of them winning exactly 6 games, P(X=6), added to the probability of them winning all seven games, P(X=7).
This problem can be treated as a binomial probability model with probability of success p = 0.38 in each of n = 7 games.
Thus:
The probability is:
The probability that the Islanders will win at least six out of seven games in a series against the Rangers is 0.014.
Answer:
Step-by-step explanation:
Given that zeroes of a polynomial are
-3, -1, 1, 4
Degree of the polynomial is 4
Also leading coefficient is 1.
So we find easily the polynomial
Since polynomial is 0 at the given four points the polynomial is a product of
Since leading coefficient is given to be 1 we need not multiply an arbitrary constant a
so the required polynomial is
Answer:
- -7.5x -12.5, x < -1
- 7.5x +2.5, x ≥ -1
Step-by-step explanation:
The absolute value function changes slope at its vertex. Here, that vertex is translated to x = -1. To the left of that point, the function is equivalent to one that negates its argument:
|x| = -x . . . for x < 0
|x| = x . . . for x ≥ 0
<u>for (x+1) < 0</u>
y = -7.5(x +1) -5 = -7.5x -12.5
<u>for (x+1) ≥ 0</u>
y = 7.5(x +1) -5 = 7.5x +2.5
This means we can write the piecewise function as ...
