You draw a card at random from a deck that contains 333 black cards and 777 red cards. What is \text{P(draw a black card})P(draw a black card)start text, P, left parenthesis, d, r, a, w, space, a, space, b, l, a, c, k, space, c, a, r, d, end text, right parenthesis? If necessary, round your answer to 222 decimal places.
Answer:
The probability of picking a black card at random, from a deck with 3 black cards and 7 red ones is 0.3.
Step-by-step explanation:
We will assume that we have 3 black cards and 7 black cards, for a total of 10 cards. Since we are taking one card at random, we can assume that each card is equally likely to be drawn. We have the following event A: The drawn card is a black. We will find the probability of A as counting the number of outcomes that make A to occur and divide it by the total number of possibilities. We are drawing one card, so we have 10 possibilities to be picked. Out of those 10, only 3 cards are black, hence we have 3 possibilites of picking a black card.
Then,
P(A) = 3/10 = 0.3.
Answer:
0.435 Got it from Khan
Step-by-step explanation:
Hint #11 / 3
All of the probabilities in a valid probability distribution must add up to 111.
Hint #22 / 3
Solve for the missing probability:
\begin{aligned} 0.475+\text{?}+0.090&=1 \\\\ 0.565+\text{?}&=1 \\\\ \text{?}&=0.435 \end{aligned}
0.475+?+0.090
0.565+?

A 48-inch board is cut into two pieces. One piece is three times the length of the other. Find the length of the shorter piece. The shorter piece is ______
inches long.
Answer:
12 inches long
Step-by-step explanation:
So you have the ratio x : 3x
4x = 48
x = 12
Plug in:
12 * 1 = 12
The length of the shorter piece is 12 inches if the 48-inch board is cut into two pieces. One piece is three times the length of the other.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
A 48-inch board is cut into two pieces. One piece is three times the length of the other.
Let x and y be the length.
x = 3y
x + y = 48
3y + y = 48
y = 12 inches
x = 36 inches
Thus, the length of the shorter piece is 12 inches if the 48-inch board is cut into two pieces. One piece is three times the length of the other.

Of all 840 sixth grade students in a math school, 700 participated in the math Olympiad. Of all 910 fifth grade students, 745 participated in it.From which grade did more students participate in the Olympiad?
Answer:Sixth grade
Step-by-step explanation:
Given
There are [tex]840[/tex] sixth grade students out of which [tex]700[/tex] Participated in math olympiad
also no of fifth grade students[tex]=910[/tex]
Fifth graders who participated in math olympiad [tex]=745[/tex]
Since [tex]745>740[/tex]
There are more fifth graders in Olympiad [Numerically]
Percentage wise
Percenteage of sixth graders who participated in Math olympiad[tex]=\dfrac{700}{840}\times 100=83.33\ \%[/tex]
Percenteage of Fifth graders who participated in Math olympiad[tex]=\dfrac{745}{910}\times 100=81.86\ \%[/tex]
So, a greater Population of Sixth graders participated in math olympiad compared to Fifth graders as [tex]83.33\ \%>81.86\ \%[/tex]

Claire tossed a die onto a black-and-red checkerboard. What is the probability that it will land with a value less than 4 on a red square?
show work pls and Thanks!!
Answer:
1/4
Step-by-step explanation:
A checkerboard is 1/2 red and 1/2 black.
There are 6 sides on a die, 3 of which are less than 4 (1, 2, and 3).
So the total probability is (1/2) (3/6) = 1/4.

what is the value of x
Answer:
x = 8
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 6² = 10²
x² + 36 = 100 ( subtract 36 from both sides )
x² = 64 ( take the square root of both sides )
x = [tex]\sqrt{64}[/tex] = 8

Answer:
x =41
Step-by-step explanation:
The three angles form a straight line so they add to 180 degrees
76+ x+ 63 = 180
Combine like terms

8.2 ounces
PLEASE AWNSER ASAP WITH GIVE BRAINLEST IF U DO
Answer:
3.6 ounces.
Step-by-step explanation:
4 one half ounces = 2 ounces of paint.
So Albert uses 2 ounce and Tony uses 2 * 0.8 = 1.6 ounces.
So together they use 2+ 1.6 = 3.6 ounces.

Step-by-step explanation:
if a cylinder has a volume of approximately 125.6 cubic cm and has a height of 10cm what is the length of the radius
Answer:
radius = 4 cm
Step-by-step explanation:
To find the length of the radius, we will follow the step below;
First, write down the formula for finding the volume of a cylinder
v=πr²h
where v is the volume of a cylinder
r is the radius and
h is the height of the cylinder
from the question given,
v=125.6 and h = 10 cm
we can now proceed to insert the values into the formula and solve for r
note that π is a constant which is equal to 3.14
v=πr²h
125.6 =3.14×r×10
125.6 =31.4 r
Divide both-side of the equation by 31.4
125.6/31.4 =31.4 r/31.4
4 = r
r =4 cm
The length of the radius = 4 cm

Step-by-step explanation:
Using the tangent ratio in the right triangle
tan67° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{14}[/tex]
Multiply both sides by 14
14 × tan67° = x, thus
x ≈ 33 ( to the nearest whole number )
