Answer: 3/10
Step-by-step explanation: It's 3/10 because the total amount when you add all the numbers together is 120, and since he spins it 120 times, we could assume that 36 would be the amount of times that it would land on it based on the data given. We're not done yet though. You do 36/120 to get the probability, and you simplify it to get 3/10.
The probability that Ricardo spins blue on his next spin is 0.3
We could use the principle of experimental probability to determine the probability of spinning blue on next spin :
Given that :
Red: 35
Blue: 36
Green: 32
Yellow: 8
Orange: 9
Experimental probability = (number of times event occur / total number of trials)
Total number of trials = (35 + 36 + 32 + 8 + 9) = 120
The experimental probability of spinning blue is thus :
(Number of blue spins / total number of spins)
= 36 / 120
= 0.3
The probability of spinning blue on next spin is 0.3

a) meters squared
b) kelvins

d) milimeters
Answer:
meters squared
Step-by-step explanation:
kelvin is used to measure temperature. so that isn't it. centimeters cubed is a small measurement and isn't used for a 2d surface like the rug that covers the floor. and millimeters is too small to measure for a rug. the answer is meters squared.

Describe the nature of the roots for the equation 49x^2-
28x +4 = 0
O one real root
one complex root
O two complex roots
O two real roots
Answer:
Step-by-step explanation:
One real root
The nature of the roots of [tex]\mathbf{49x^2 - 28x + 4 = 0}[/tex] is (a) one real root
The equation is given as:
[tex]\mathbf{49x^2 - 28x + 4 = 0}[/tex]
To determine the nature of the roots, we make use of determinants.
The determinant (d) of a quadratic equation is calculated
[tex]\mathbf{d = b^2 - 4ac}[/tex]
Where the quadratic equation is:
[tex]\mathbf{ax^2 + bx + c = 0}[/tex]
By comparison, we have:
[tex]\mathbf{a = 49,\ b = -28,\ c = 4}[/tex]
So, we have:
[tex]\mathbf{d = b^2 - 4ac}[/tex]
[tex]\mathbf{d = (-28)^2 - 4 \times 49 \times 4}[/tex]
[tex]\mathbf{d = 784 - 784}[/tex]
[tex]\mathbf{d = 0}[/tex]
When d = 0, then the function has one real root.
Hence, the nature of the roots of [tex]\mathbf{49x^2 - 28x + 4 = 0}[/tex] is (a) one real root

A painter mixes cans of green and white paint to make the shade needed for painting a bedroom. The table shows the
ratios he can use for the color he wants.
Green cans (g) 6 10 16 18
White cans (W) 915 24 27
Which is a direct variation equation for this relationship?
Answer:
A. 2/3w
Step-by-step explanation:
Option A is correct, g = 2/3 w is a direct variation equation for the given relationship
To determine the direct variation equation, we need to check if the ratio of green cans (g) to white cans (w) is constant across all the given ratios.
Let's calculate the ratios for each case:
For the first ratio: g = 6 and w = 9
g/w = 6/9
= 2/3
For the second ratio: g = 10 and w = 15
g/w = 10/15
= 2/3
For the third ratio: g = 16 and w = 24
g/w = 16/24
= 2/3
For the fourth ratio: g = 18 and w = 27
g/w = 18/27
= 2/3
Since the ratio of g/w is the same (2/3) for all cases, we can see that the relationship between green cans (g) and white cans (w) is a direct variation
Hence, the direct variation equation is g = 2/3 w, option A is correct.

If h and j are inverse functions, what is h(j(15))
Answer: 15
Step-by-step explanation:
Let's define the concept of inverse functions.
If we have a function h(x), such that it has an inverse, and:
h(x) = y.
Then the inverse function j(x) must meet the following:
j(y) = x.
Now, we want to calculate:
h( j(15) ).
Let's suppose that:
j(15) = A.
(Where A can be any real number).
then, by the above relation, we must have that:
h(A) = 15.
Now we can replace j(15) by A in h(j(15)):
h( j(15) ) = h( A ) = 15.

George deposits $3,500 at 3.25% interest compounded monthly. What will his ending balance be after 5 years?
Answer:
FV= $4,117.1
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $3,500
Number of periods= 5*12= 60 months
Interest rate (i)= 0.0325/12= 0.00271
To calculate the Future Value, we need to use the following formula:
FV=PV*(1+i)^n
FV= 3,500*1.00271^60

The discriminant of a quadratic equation is 34. Which of the following is true about its roots? *
a.The roots are imaginary and unequal.
b.The roots are real, rational, and unequal.
c.The roots are real, irrational and unequal.
d.The roots are real, rational and equal.
Answer:
d. The roots are real, rational and equal.Step-by-step explanation:
The discriminant of a quadratic equation is expressed using the equation:
D = b²-4ac. It talks about the nature of the roots of a quadratic equation.
If D>0, then the roots is real and unequal/distinct
If D<0 the roots are unreal and imaginary
If D = 0, the roots are real and equal (one real root)
According to this question, since the root given is a real value and also one value, then the the roots are real, rational and equal. Note that the root is rational since we can write it as a ratio of two integers e.g 34 = 34/1. 34 and 1 are integers
