Answer:
9c + 45
Step-by-step explanation:
The distributive property also known as distributive law of multiplication and division.
In the given expression, distributive law of multiplication is applied where we can multiply first before addition.
Given
9(c+5)
Using distributive property
9(c+5)
= (9 × c) + (9 × 5)
= 9c + 45
9(c+5) = 9c + 45
Answer:
10y + 20 -11 =139
10y = 130
y = 130 / 10
y = 13
Step-by-step explanation:
Answer:
c = -3
Step-by-step explanation:
The discriminant is 73, that means we have:
(-1)^2-4*6*c=73
then: 1-24c=73
or -24c= 73 -1
-24c = 72
Then c = 72/-24= -3
The answer is -3

Answer:
4:3
Step-by-step explanation:
The computation of the ratio of females to males is shown below
Since it is mentioned that there is 28 students in the class out of which 12 are boys
So, the females are
= 28 - 12
= 16
SO, the ratio of females to males is
16:12
4:3
12.5% is the percentage of numbers randomly generated by Taylor's computer that is less than 0.5.
An illustration of a numerical distribution with continuous results is a density curve. A density curve is, in other words, the graph of a continuous distribution. This implies that density curves can represent continuous quantities like time and weight rather than discrete events like rolling a die (which would be discrete). As seen by the bell-shaped "normal distribution," density curves either lie above or on a horizontal line (one of the most common density curves).
The percentage of numbers randomly generated by Taylor's computer are less than 0.5 is given by
P(0≤X≤0.5)
=



= 0.125
That is 12.5%
