<span>First we calculate z using the formula:
z = (x - μ)/σ</span>
Where:
x = our variable, 10
μ = mean, 8
σ = standard dev, 2
Substituting known
values:<span>
z = (10 - 8)/2
z = 2/2
z = 1
Using the tables of
the normal distribution to find the p-value with z = 1
p = 0.8413
Since we want
"greater than 10”, we need to subtract the probability from 1
therefore
p* = 1 - 0.8413 = <span>0.1587</span></span>
Answer:
3/8
Step-by-step explanation:
Given:
- 2 cheese balls in walnuts
But she has 3/4 cup of pecans, so each cheese balls in pecans is: 3/4:2 = 3/8
So the fraction of a cup can she use for each cheese ball is: 3/8
Answer:
Yes, there are infinite similar triangles with the same three angles and different side lengths
Step-by-step explanation:
we know that
If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
so
There are infinite similar triangles with the same three angles and different side lengths
Answer:
all real numbers
Step-by-step explanation:
3x-8 = -x + 4(x-2)
distributive property:
3x - 8 = -x + 4x-8
Combine like terms:
(add 3x to both sides)
-8 = -8
That means that x can be any number, because in the end, x will be canceled out from the equation.
