Answer:
A) 3
Step-by-step explanation:
Slope defines the rate of a change in a linear equation. As the function is written in slope-intercept form, mx + b, in which m is the slope and b is the y-intercept, 3 is your slope.
Probablity is (desired outcomes)/(total possible)
desired is your tickets: 5
total possible=500
probability is 5/500=1/100=1%
Answer:
86.53
Step-by-step explanation:
Area of Triangle Formula: A = 1/2bh
Pythagorean Theorem: a² + b² = c²
Step 1: Draw altitude and label numbers
If we draw a line down the middle, we can see that we get a perpendicular bisector and that we get 2 right triangles with a hypotenuse of 29 and a leg of 3. We need to find <em>h</em> using Pythagorean Theorem in order to use area formula:
3² + b² = 29²
b² = 29² - 3²
b = √832 = h
Step 2: Plug in known variables into area formula:
A = 1/2(√832)(6)
A = 3√832
A = 86.5332
It’s A because I took this test
Work out the z scores for 51 and 54
z1 = (51 - 57.5) / 6.5 = -1
z2 = (64 - 57.5)/6.5 = 1
from tables of normal distribution this value os 3413 + 3413 = 68.26%
so the answer is c
