34% of the scores lie between 433 and 523.
Solution:
Given data:
Mean (μ) = 433
Standard deviation (σ) = 90
<u>Empirical rule to determine the percent:</u>
(1) About 68% of all the values lie within 1 standard deviation of the mean.
(2) About 95% of all the values lie within 2 standard deviations of the mean.
(3) About 99.7% of all the values lie within 3 standard deviations of the mean.
Z lies between o and 1.
P(433 < x < 523) = P(0 < Z < 1)
μ = 433 and μ + σ = 433 + 90 = 523
Using empirical rule, about 68% of all the values lie within 1 standard deviation of the mean.
i. e. 
Here μ to μ + σ = 
Hence 34% of the scores lie between 433 and 523.
I think it’s 25....Yeah I’m pretty sure it’s 25
Answer:
The answer would be A
Step-by-step explanation:
When you draw TV with V being the midpoint of SU, you would have two triangles that are congruent on all three sides (SSS). See picture. Hope this helped :)
Answer:
<h3>Step 1 - Find the gradient of 2x + 4y = 16</h3>
2x + 4y = 16
4y = 16 - 2x
y = 4 - 1/2x
gradient = -1/2
<h3>Step 2 - Find the Equation</h3>
y - y1 = m(x - x1)
m = gradient, (x1, y1) = (-2,2)
y - 2 = -1/2 (x + 2)
y - 2 = -1/2x - 1
y = -1/2x + 1 → ANSWER

Answer: t= -0.799
This can also be written as t= -0.8
How to do it :
4.74t+ 5 = 13.5t + 12
first, subtract 4.74t from both sides
5= 8.76t + 12
next, subtract 12 from each side
-7 = 8.76t
next, divide 8.76 from each sides
-0.799 = t
