Answer:
They cannot afford the monitors
Step-by-step explanation:
Given that the cost of a monitor is $89
and the school is willing to buy up to 200 monitors
We can calculate the total cost of all the 200 monitors as
200*89= $17,800
Given that the school only has $ 15,000 to spend on the monitor
they cannot afford the amount as they still have a deficit of $2,800
Tanya drives to work every day and passes two independently operated traffic lights. The probability that both lights are red is 0.55. The probability that the first light is red is 0.69. What is the probability that the second light is red, given that the first light is red?
0.83
0.75
0.80
0.73
Answers
Answer:
(C) 0.80
Step-by-step explanation:
Let the probability that the first light is red is= and
the probability that the second light is red= . Then,
Probability that both lights are red= = 0.55,
Probability that the first light is red= =0.69,
Probability that the second light is red, given that the first light is red==
=
=
≈
Probability that both lights are red 0.55
Probability that 1st light is red 0.69
Find the probability that the 2nd light is red, given that the first light is red.
0.55/0.69 = 0.797 or 0.80
The probability that the 2nd light is red while the 1st light is also red is 0.80.

The slope of any line parallel to y = 3x - 4 is also 3.
The given equation is y = 3x - 4 , I will assume you meant to write:
y = 3x - 4
To find the slope of a line parallel to this line, we can observe that parallel lines have the same slope. The equation of the given line is in the slope-intercept form y = mx + b, where "m" represents the slope. In this case, the slope (m) of the line is 3.
So, the slope of any line parallel to y = 3x - 4 is also 3.

Answer: If the original equation is y = 3x -4, the slope is 3.
Any equation of a line parallel to the line y = 3x -4 will have a slope of 3.
Step-by-step explanation:
In slope-intercept form, y =mx + b the coefficient of x, m is the slope.
Here 3 is that value.
It is very unusual to have two equal signs in a question about slope.

We need to first of all find the volume of the fish tank. The most probable shape the ship tank can have is that of a cuboid.
The volume of a cuboid is l * b * h
And this is equals 30cm * 70cm * 90cm = 189,000 cubic centimeters
The number of fish the tank can contain can be obtained by dividing the volume by the volume occupied by a single fish.
This is 189,000/27000 = 7

Step-by-step explanation:
8n + 2 = 5n + 11
Subtract 5n from each side
8n-5n + 2 = 5n-5n + 11
3n+2 = 11
Subtract 2 from each side
3n+2-2 = 11-2
3n = 9
Divide by 3
3n/3 = 9/3
n =3
Answer:
n=3
Step-by-step explanation:
Let's do the algebra step-by-step.
8n+2=5n+11
-2 -2
8n=5n+9
-5n -5n
