Answer:
25
Step-by-step explanation:
X² = 7² + 24²
X² = 49 + 576
X² = 625
X = 25
Answer:
Step-by-step explanation:
180
The correct answer for the question that is being presented above is this one: "2(x - 1)(3x + 4) = 0."
<span>6x 2 + 2x - 8 = 0
(2x - 2) (3x + 4) = 0
2(x - 1)(3x + 4) = 0
The correct answer for the question that is being presented above is this one: "</span><span>(x - 4)^2 = -19."</span><span>
x2 - 8x + 3 =0
x2 - 8x + 16 = -3 - 16
(x - 4)(x - 4) = -19
(x - 4)^2 = -19</span>
-3 x -26 = 78
meaning the answer is D.
The reason the answer is D, is because two negatives when multiplied or divided become positive. Only when multiplied or divided does this occur.
Answer:
P(X<1200) is 0.8212
Step-by-step explanation:
Test statistic (z) = (X - mean)/sd
X is score of a tester = 1200
mean = 1497
sd = 322
z = (1200 - 1497)/322 = -297/322 = -0.92
The cumulative area of the test statistic is the probability that X<1200. The cumulative area is 0.8212.
Therefore, P(X<1200) = 0.8212
