what is the probability of drawing two yellow marbles if the first one is placed back in the bag before the second draw. give your answer as a ratio reduced to simplest terms.
Answers
The probability that both marbles are yellow marbles is 1/25
How to determine the probability?The given parameters are:
Yellow = 2
Total = 10
The probability of selecting the first yellow marble :
P(Yellow) = 2/10
When the marble is returned, we have:
Yellow = 2
Total = 10
The probability of selecting the second yellow marble :
P(Yellow) = 2/10
The required probability is:
P = 2/10 * 2/10
Evaluate
P = 4/100
Simplify
P = 1/25
Hence, the probability that both marbles are yellow marbles is 1/25

find the probability of getting a prime number on the dice and head on the coin when a dice is rolled and a coin is tossed simultaneously.
Answers
Answer:
1/4
Step-by-step explanation:
For a die,
the number of possible results is 6
The prime numbers are 2,3,5
the probability of getting a prime number is thus; 3/6 = 1/2
Tossing a coin, the probability of getting a head is also 1/2
So the probability of getting both on a single toss will be;
1/2 * 1/2 = 1/4
According to the question,
The number of possible results,
6Prime numbers,
2, 3 and 5Now,
The probability of getting a prime number will be:
= [tex]\frac{3}{6}[/tex]
= [tex]\frac{1}{2}[/tex]
then, by tossing the coin head's probability is "[tex]\frac{1}{2}[/tex]".
hence,
Getting both on single toss will be:
= [tex]\frac{1}{2}\times \frac{1}{2}[/tex]
= [tex]\frac{1}{4}[/tex]
Thus the above answer is right.

Mei wants to solve the inequality --W < 12. How can she isolate the variable?
2
• Multiply both sides by -2 and reverse the inequality symbol.
• Multiply both sides by -2 and do not reverse the inequality symbol.
*) Divide both sides by 12 and reverse the inequality symbol.
) Divide both sides by 12 and do not reverse the inequality symbol.
Answers
Answer:
Multiply both sides by -2 and reverse the inequality symbol.
Step-by-step explanation:
To isolate w, multiply both sides by the reverse of -1/2 (because -1/2*2=1 ), which is -2
When multiplying or dividing by negatives, you must reverse the inequality symbol as well.
To isolate the variable, you multiply both sides by -2 and reverse the inequality symbol.
Isolating variables in inequalityIsolation of variables means making the variable the subject of the formula from the given expression.
Given the inequality expression -1/2 w < 12
To make w the subject of the formula, we will have to multiply both sides by -2 to have;
-1/2 w * -2 > 12 * -2
w > -24
Hence to isolate the variable, you multiply both sides by -2 and reverse the inequality symbol.

The cosine of A is equal to [tex]\frac{3\sqrt{58}}{58}\\[/tex]
Step-by-step explanation:
Cosine is is calculated as adjacent over hypotenuse. The line adjacent to A is 3 in length.
So we can say that the cosine is equal to 3/√58, but need to multiply it by √58 / √58 to ensure we have a non-radical denominator
[tex]A = \frac{3}{\sqrt{58}}\\A = \frac{3\sqrt{58}}{58}\\[/tex]

Answers
Answer:
27°C

The temperature on February 9th 1934 = -15°C
The next day the temperature rose 42 degrees.
We need to find an expression for the temperature on February 10th.
February 10th temperature = -15 + 42
= 27°C
So, the temperature on February 10th is 27°C.

y +2 = -1/2(x -7)
Step-by-step explanation:
The line PQ has a rise of 6 units for a run of 3 units, so its slope is ...
m = rise/run = 6/3 = 2
A line perpendicular to PQ will have a slope that is the opposite reciprocal of that, so ...
-1/m = -1/2
We have the slope of the desired line, and a point it needs to pass through, so we can use the point-slope form of the equation of a line.
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
An equation for the desired line is ...
y +2 = -1/2(x -7)

Step-by-step explanation:
According to the law of sines [tex]\frac{sinA}{a}[/tex] = [tex]\frac{sinb}{b}[/tex] = [tex]\frac{sinc}{c}[/tex].
In this triangle we have two sides with two of their angles.
Let's make 8 cm side a with 38º as its angle, and 11 cm side b with x as its angle.
[tex]\frac{sinx}{11}[/tex] = [tex]\frac{sin38}{8}[/tex]
Now we multiply both sides by 11 to get rid of the denominator on the left.
sinx = [tex]\frac{11sin38}{8}[/tex]
To find x, we use inverse sine.
x = sin⁻¹ (11sin38/8)
Plug this into a calculator, and you will get 57.837.
Round this to 57.8º
Hope this helps!
