one card is drawn from a pack of 52cards each of the 52 cards being equally likely to be drawn. what is the probability that the card drawn is a king?
The probability of drawing a king from a standard deck of 52 cards is 1/13.
In a standard deck of 52 playing cards, there are four kings: the king of hearts, the king of diamonds, the king of clubs, and the king of spades.
To find the probability of drawing a king, we need to determine the ratio of favorable outcomes (drawing a king) to the total number of possible outcomes (drawing any card from the deck).
The total number of possible outcomes is 52 because there are 52 cards in the deck.
The favorable outcomes, in this case, are the four kings.
Therefore, the probability of drawing a king is given by:
Probability = (Number of favorable outcomes) / (Number of possible outcomes)
= 4 / 52
= 1 / 13
Thus, the probability of drawing a king from a standard deck of 52 cards is 1/13.
This means that out of every 13 cards drawn, on average, one of them will be a king.
It is important to note that the probability of drawing a king remains the same regardless of any previous cards that have been drawn or any other factors.
Each draw is independent, and the probability of drawing a king is constant.

A. (x + 2)^2 + (y + 8)^2 = 25
B. (x - 2)^2 + (y – 8)^2 = 10
C. (x + 2)^2 + (y + 8)^2 = 10
D. (x + 2)^2 + (y + 8)^2 = 100
E. (x - 2)^2 + (y - 3)^2 = 100
Answer:
C. \( (x +2) ^2 +(y+8)^2 =10 \)
Step-by-step explanation:
Center of the circle (h, k) = (-2, - 8)
Radius \( r=\sqrt {10}\)
Equation of circle in center radius form is given as:
\( (x - h) ^2 +(y-k) ^2 =r^2 \)
Plugging the values of h, k and r in the above equation, we find:
\( [x - (- 2)] ^2 +[y-(-8) ]^2 =(\sqrt {10})^2 \)
\( (x +2) ^2 +(y+8)^2 =10 \)
A shoe manufacturer claims that among the general adult population in the United States that the length of the left foot is longer than the length of the right foot. To compare the average length of the left foot with that of the right foot, we will take a random sample of adults and measure the length of the left foot and then the length of the right foot. Based on our sample, does the data indicate that the length of the left foot is greater than the length of the right foot? Is the hypothesis one-tailed or two-tailed?
We can reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis that the left foot is longer than the right foot.
How to test the data indicate that the length of the left foot is greater than the length of the right foot?A statistical test is required to determine whether the length of the left foot is greater than the length of the right foot. The null hypothesis states that there is no difference in average length between the left and right feet. The alternative hypothesis is that the left foot's average length is greater than the right foot's average length.
This hypothesis is one-tailed, as we are only interested in whether the left foot is longer than the right foot. We are not considering the possibility that the right foot could be longer than the left foot.
A t-test can be used to determine whether the difference in average length between the left and right feet is statistically significant. We can reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis that the left foot is longer than the right foot if the p-value of the t-test is less than the chosen significance level (e.g., 0.05).

A recent poll of 1500 new home buyers found that 60% hired a moving company to help them move to their new home. Find the margin of error for this poll if we want 95% confidence in our estimate of the percentage of new home buyers who hired movers.
Answer:
The margin of error M.O.E = 2.5%
Step-by-step explanation:
Given that;
The sample size = 1500
The sample proportion \(\hat p\) = 0.60
Confidencce interval = 0.95
The level of significance ∝ = 1 - C.I
= 1 - 0.95
= 0.05
The critical value:
\(Z_{\alpha/2} = Z_{0.05/2} \\ \\ Z_{0.025} = 1.96\) (From the z tables)
The margin of error is calculated by using the formula:
\(M.O.E = Z_{\alpha/2} \times \sqrt{\dfrac{\hat p(1 -\hat p)}{n}}\)
\(M.O.E = 1.96 \times \sqrt{\dfrac{\hat 0.60(1 -0.60)}{1500}}\)
\(M.O.E = 1.96 \times \sqrt{\dfrac{0.24}{1500}}\)
\(M.O.E = 1.96 \times \sqrt{1.6 \times 10^{-4}}\)
M.O.E = 0.02479
M.O.E ≅ 0.025
The margin of error M.O.E = 2.5%

What is the area of the rhombus? 11 m2 15 m2 22 m2 44 m2
Answer:
44 m2
Step-by-step explanation:
The area of the rhombus can be divided into 4 equal triangles.
The area of one triangle is A=bh/2
so:
A = 5.5*2
A = 11 squared m
Since there are four (4) triangles in the rhombus we just need to multiply 11 by 4 so:
A = 11 * 4
A = 44 squared m
if the letter l,o,g,ic are randomnly arranged to form word logic what is the probability that result will be woord logic
The probability of randomly forming the word "woord logic" is:Probability = 1 / (10! / (2!))
To calculate the probability of forming the word "woord logic" by randomly arranging the letters l, o, g, i, c, we need to consider the total number of possible arrangements and the number of arrangements that result in the desired word.
The word "woord logic" has 10 letters in total. Among these letters, there are 2 o's and the remaining letters appear only once.
The total number of possible arrangements is given by the factorial of the total number of letters:
Total arrangements = 10!
However, since the letter "o" appears twice, we need to divide by the factorial of the number of repeated letters:
Total arrangements = 10! / (2!)
To calculate the number of arrangements that result in "woord logic," we consider that the arrangement of "woord logic" is unique and distinct. Thus, there is only one arrangement that matches the desired word.Simplifying this expression would yield the exact probability.

Use the distributive property with factoring to find the equivalent expression.
21x + 39z = (7x + z)
The equivalent expression is 14x + 38z = 0.
What is an expression?We have to note that an expression has to do with a mathematical statement. According to the distributive property, we can be able to open up the brackets over the values that we have in the question.
As such we would have;
21x + 39z = (7x + z)
Removing the brackets;
21x + 39z = 7x + z

John has a 100 cm cubed pencil holder. If John wants to hide a pencil in the pencil holder (so the pencil holder) what is the longest length of pencil he can hide
Therefore, the longest length of pencil that John can hide in the pencil holder is approximately 127.32 cm (rounded to two decimal places).
Given that John has a 100 cm³ pencil holder, the longest length of pencil he can hide in the pencil holder can be found by using the formula for the volume of a cylinder which is given by: V = πr²h where r is the radius of the cylinder and h is the height of the cylinder.The volume of a cylinder can also be expressed as V = lwh where l is the length of the cylinder, w is the width of the cylinder and h is the height of the cylinder.
If we assume that the pencil is cylindrical in shape, then its volume can be given by V = πr²l where r is the radius of the pencil and l is the length of the pencil.Since the volume of the pencil holder is given to be 100 cm³, then we have:100 = πr²h (Equation 1)
Now, we need to find the value of l that can fit inside the pencil holder. We can use the formula for the volume of the pencil to do this as follows:
V = πr²lLet V = 100 cm³ and
r = 0.5 cm
(since the pencil holder is cylindrical in shape, we can assume that it has a radius of 0.5 cm)Then, we have:100 = π(0.5)²lSolving for l, we get:
l = 100 / (π(0.5)²)
l = 100 / (0.7854)l ≈ 127.32 cm

Consider drawing two cards, without replacement, from a standard deck of 52 cards. That means we are drawing the first card, leaving it out, and then drawing the second card.what is the probability that both cards selected for black?
Given:
Two cards are drawn from a standard deck of 52 cards without replacement.
To find:
The probability that both cards selected for black.
Solution:
We know that,
Total number of cards = 52
Total number of red cards = 26
Total number of black cards = 26
\(\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}\)
Probability of selecting first black card is
\(\text{Probability}=\dfrac{26}{52}\)
\(\text{Probability}=\dfrac{1}{2}\)
Number of remaining total cards = 52-1 = 51
Number of remaining black cards = 26-1 = 25
Probability of selecting second black card is
\(\text{Probability}=\dfrac{25}{51}\)
So, the probability that both cards selected for black is
\(\text{Probability}=\dfrac{1}{2}\times \dfrac{25}{51}\)
\(\text{Probability}=\dfrac{25}{102}\)
Therefore, the required probability is \(\dfrac{25}{102}\).
A walkway forms one diagonal of a square playground. The walkway is 14 m long. How long is a side of the playground?
Answer: The side of the playground is around 10 meters long
Step-by-step explanation:
use the diagonal as the hypotenuse of a right triangle, where the sides of the square form the legs of said triangle.
Usually
\(a^{2} +b^{2} =c^{2}\)
since we know a and b are the same length (sides of a square are congruent) we would have
\(a^{2} +a^{2} =c^{2} \\2a^{2} =c^{2}\)
We know that c is 14 so
\(2a^{2} =14^{2} \\2a^{2} =196\\a^{2} =98\\a=\sqrt{98} \\a= 9.999\)
