Theorem: When two secants meet at an external point, the products of the secant and the external segment are equal.
In essence, we are saying that QR × PR = TR × SR
Thus, 16 × 6 = 8(x + 8)
96 = 8(x + 8)
Dividing both sides by 8, we produce:
12 = x + 8
x = 4
Thus, we can conclude that the missing side, x, is 4.

Answer:
we arrive at the conclusion that the new employee installs the vertical blinds faster on average.
Step-by-step explanation:
null hypothesis; m₁-m₂ =0
alternative hypothesis; m₁-m₂<0
Given the information in this question, we first have to solve for the t statistic
t = -7.018
the degree of freedom = n₁+n₂-2
= 10+10-2
= 18
Alpha α = 0.05
from these results the t critical value = -1.734
because the test statistic -7.018 < -1.734,
at 0.05 level of testing, we arrive at the conclusion that the new employee installs the vertical blinds faster on average than the veteran.
Answer:
y = -3x + 13
Step-by-step explanation:
y - 4 = -3(x - 3)
y - 4 = -3x + 9
y = -3x + 9 + 4
y = -3x + 13
