Answer:
I think d.) 1
Step-by-step explanation:
1/2 and 3/4 is a 1/4 difference bc 1/2= 2/4
3/4 + 1/4 is a cup. I may be wrong
Given:
z = (x - μ)/σ = z value
x = independent variable = 11
μ = mean = 8
σ = standard deviation = 3
Solution:
X ~ N (8, 3)
For day 1, n = 5
P (X < = 11) = P (Z < = 11 – 8 / 3/Sqrt5) = P (Z <
=2.23) = 0.987126
For day 1, n = 6
P (X < = 11) = P (Z < = 11 – 8 / 3/sqrt6) = P (Z <
=2.45) = 0.992857
For both days:
P (X <= 11) = P (X <= 11) = (0.987126) (0.992857) =
0.9801
Answer:
$12
Step-by-step explanation:
first we multiply the candies by the weight to find out the total weight
60* 25= 1500g
1500g to kg = 1500/1000 = 1.5kg
so its going to be 1.5kg * 8
1.5* 8 = 12
Answer:
148⁰
Step-by-step explanation:
Since
we know that the angle in a straight line is 180⁰
<axb+<bxd=180⁰
Given
<axb=32⁰
Therefore
<bxd=180⁰-32⁰=148⁰
Option D
9514 1404 393
Answer:
64 -16π square units
Step-by-step explanation:
The area of the square is ...
A = (8 units)^2 = 64 units^2
The area of the circle is ...
A = πr^2 = π(4 units)^2 = 16π units^2
The shaded area is the difference:
shaded area = (64 -16π) units^2.
