Answer:
2/5 of iron
Step-by-step explanation:
∵ 3/4 cup of oatmeal contains 1/10 of iron.
∴ 1 cup of oatmeal will contain 
=2/5 of iron
Answer:
x = 117°
Step-by-step explanation:
The angle inside the triangle and 101° are adjacent and supplementary, thus
angle inside triangle = 180° - 101° = 79°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of the triangle , thus
x = 38° + 79° = 117°
Answer:
0.206
Step-by-step explanation:
Use binomial probability.
P = nCr pʳ qⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1−p).
n = 15, r = 10, p = 0.7, and q = 0.3.
P = ₁₅C₁₀ 0.7¹⁰ 0.3⁵
P = 0.206
We know that the total is 180 degrees of the lines.
To find x:
(5x+20)+(4x-11) = 180
x=19
To find y, input the value of x into the equation 4x-11 since this equation is equal to 2y+19
4(19)-11 = 65
2y+19 = 65
y=23
Out of all the numbers from 1 to 80, there are (80-20)/(80) = 60/80 = 0.75
of them that are greater than 20 .
So every time you pick one at random, there a 75% chance that it will be
greater than 20.
If everything works out according to pefectly random probabilities, then
in 180 selections, 75% of them = (0.75 x 180) = <em>135 of the selections</em>
would be numbers greater than 20 .
