Answer:
Our score = 0.60, Amanda's score = 0.25
Step-by-step explanation:
For Amanda
μ = 15 , σ = 4
z- score for X = 16 is (From z table)
z = (X - μ)/σ = (16 - 15)/4 = 0.25
For us
μ = 310 , σ = 25
z score for X = 325 (From z table)
z = (325-310)/25 = 0.60
Since our z score is better than Amanda's z score, we can say we did better
Answer:
∠Q = 75 °
Step-by-step explanation:
Since PR = PQ then Δ PQR is isosceles and the base angles are congruent, that is
∠R = ∠Q = 2x + 15
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
2x + 15 + 2x + 15 + x = 180, that is
5x + 30 = 180 ( subtract 30 from both sides )
5x = 150 ( divide both sides by 5 )
x = 30
Hence
∠Q = 2x + 15 = (2 × 30) + 15 = 60 + 15 = 75°
Answer:I am pretty sure it is 2
Step-by-step explanation:
Answer:
The height would be 14in.
Step-by-step explanation:
Do 10 1/2 divided by 3/4.
Work:
10 1/2 = 21/2
21/2 / 3/4
21/2 x 4/3 = 84/6
84/6 = 14
electricity comes from electrons, does morality come from morons? No, you're thinking of mormality. That is true, especially in the US. ... This means that the stupider a group is overall, the less moral they are expected to beon:
