In a classroom of 30 students, in which 18 are girls and 12 are boys, what is the probability that two boys are selected without replacement by the teacher?
Answer:
about 4 out of 10
Step-by-step explanation:
Probabilities are used to determine the chances of events
The probability that two boys are selected is 0.1517
The given parameters are:
Boys = 12
Girls = 18
Total = 30
Given that the selection is without replacement, the probability that two boys are selected is:
p = 12/30 * 11/29
So, we have:
p = 0.1517
Hence, the probability that two boys are selected is 0.1517

About 16 weeks ago, there were 59 mold spores found in a garden. After a few weeks of observation, it is determined that the number of mold spores in the garden is tripling every 8 weeks.
The number of mold spores, M, at any given time in the garden is equal to the product of the initial amount of spores, I, and 3 to the power of n, where n is the number of times the amount of mold spores has tripled.
How many mold spores are in the garden today?

The measure of angle Q is 70 degrees. Find the measure of angle P.
Answer:
∠ P = 40°
Step-by-step explanation:
Since PQ = PR then the triangle is isosceles and the base angles are congruent, then
∠ R = ∠ Q = 70° , so
∠ P = 180° - (70 + 70)° ← sum of angles in triangle is 180°
∠ P = 180° - 140° = 40°

What is an equation of the line that contains the point (0, -5) and a slope of 1/4
Answer:
y=1/4x-5
Step-by-step explanation:
Answer:
y = 1/4x - 5
Step-by-step explanation:
y = mx + b is the equation of a straight line.
m = slope, b = y intercept. (y intercept is the point where the line of the graph crosses the y axis)
(0, -5) is the y intercept (if you were to graph this point, it would be on the y axis, fitting the previous description)
the slope is 1/4
replace each variable in the equation, and you get:
y = 1/4x - 5

Answer
The answer is negative 14.
Step-by-step explanation:
When you add a negative by a negative it equals a negative. Like if you add 1 + 1 it's going to equal 2 which is a positive, not a negative. So the answer is technically 8 + 6 which is 14 and all you have to do is add a negative sign.

Maribeth saved $25 per week. She has saved a total of $600. For how many weeks has Maribeth been saving?
Answer:
24 weeks.
Step-by-step explanation:
25x = 600
divide both sides by 25 to get:
x = 24
Answer:
24 weeks
Step-by-step explanation:
use y = mx+b
y = total amount saved = $600
m = amount saved per week = $25
x = number of weeks saving = ?
b is not needed in this problem
600 = 25X
x = 600/25
x = 24
Find the value of x in the triangle shown below.
Answer:
[tex] x = \sqrt{17} [/tex]
Step-by-step explanation:
By Pythagoras Theorem:
[tex]x = \sqrt{ {9}^{2} - {8}^{2} } \\ \\ x = \sqrt{81 - 64} \\ \\ x = \sqrt{17} [/tex]
Solve the system of equations by substitution.
3x + 4y - 12
x + 7y = 8
Step-by-step explanation:
[tex]3x + 4y = 12 \\ x + 7y = 8 \\ x = 8 - 7y \\ 3(8 - 7y) + 4y = 12 \\ 24 - 21y + 4y = 12 \\ 12 = 17y \\ y = 0.705 \\ x = 8 - 7(0.705) = 3.065 = 3.07[/tex]

Answer:
Infinitely many solutions (the lines are identical)
Step-by-step explanation:
Let's start by getting each equation into slope intercept form (y=mx+b)
-14x-14y=28
-14x-28=14y
-x-2=y
and
7x+7y= -14
7x+14= -7y
-x-2=y
We can see that these two lines are identical which means that there are an infinite amount of answers
