In the figure below, X Z is a diameter of circle A.
What is the arc measure of minor arc Y Z in degrees?
Answer:
mYZ = 59°
Step-by-step explanation:
If XZ is a diameter is forms a semicircle with it's arc degree half of that of the circle, in other words 180°. That would mean:
m∠ ZAY + m∠ YAX = 180,
( 5w + 4 ) + ( 11w ) = 180,
11w + 5w + 4 = 180,
16w = 176,
w = 11°
Now mYZ is, in other words, m∠ ZAY, so let us solve for m∠ ZAY:
m∠ ZAY = 5w + 4,
m∠ ZAY = 5 * ( 11 ) + 4,
m∠ ZAY = 55 + 4,
m∠ ZAY = 59°,
mYZ = 59°

When Elena throws a shot put during track and field practice, it travels an average of 26 feet with a standard deviation of 3 feet, and the distribution of lengths is approximately normal. Approximately what percentage of her shots will travel less than 23 feet? *
Answer:
15.87%, that is, approxiately 16% of of her shots will travel less than 23 feet.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 26, \sigma = 3[/tex]
Approximately what percentage of her shots will travel less than 23 feet?
This is the pvalue of Z when X = 23. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{23 - 26}{3}[/tex]
[tex]Z = -1[/tex]
[tex]Z = -1[/tex] has a pvalue of 0.1587.
15.87%, that is, approxiately 16% of of her shots will travel less than 23 feet.
Which of the following numbers is not rational?
Answer: √5
2.7 is a rational number because it's a terminating decimal which means that the decimal does end and all terminating decimals are rational numbers.
-3 is a rational number because it's an
integer and all integers are rational.
√4 is rational because it's a perfect square which means that a number can be multiplied by itself to get 4 and that number is 2.
√5 is no rational! It's impossible to find a whole number multiplied by itself to give us 5 which means that it's
non-terminating and non-repeating.

Step-by-step explanation:
If the difference between the measures of the two smaller angles of a right triangle is 20 degrees what is the measure, in degrees, of the smallest angle?
Answer:
Measure of the smallest angle = 35 degrees.
Step-by-step explanation:
As it is a right triangle the values of the 2 smaller angles will add up to 90 degrees.
So the 2 angles can be written as x and 90-x and we have:
(90 - x) - x = 20
-2x = 20 - 90 = -70
x = 35.
So the 2 angles are 35 and 55 degrees.
In a right triangle measure of the smallest angle is equals to [tex]35[/tex] degrees.
What is angle?
" Angle is defined as when two rays meet at one point ."
According to the question,
In a right triangle,
[tex]'\theta'[/tex] represents the measure of smallest angle
[tex]'90- \theta'[/tex] represents the measure of largest angle.
As per given condition of angle we have,
[tex]90- \theta- \theta = 20\\\\\implies 2\theta = 90 + 20\\\\\implies \theta = \frac{70}{2}\\ \\\implies \theta = 35 degrees[/tex]
Hence, in a right triangle measure of the smallest angle is equals to [tex]35[/tex] degrees.

Two students factored 2x^2 + 6x - 20. Leuko said that the factorization was (2x - 4)(x + 5). Ray gave the factorization as (x - 2)(2x + 10). Confirm that both of these factorizations are correct. Then explain why they are not complete.
Answer:
See explanation
Step-by-step explanation:
If you FOIL both of them, you see that they are both correct, but they both need to factor out a 2 and then they will both have the same thing.
2(x - 2)(x + 5)
Answer: To confirm the equations to be equal with the parent function we do as follows:
(2x – 4)(x + 5) = 2x^2 + 10x - 4x - 20 = 2x^2 + 6x -20
(x – 2)(2x + 10) = 2x^2 +10x - 4x -20 = 2x^2 +6x - 20

Mary has taxable income of $40,000, with short-term capital gains of $2,500. What will be her capital gains tax rate and tax owed?

Answer:
The correct option is B,15% tax rate with $375 in taxes owed
Step-by-step explanation:
Mary has a taxable income of $40,000 which implies that Mary falls into tax bracket of capital gains tax of 15% for taxable income between $38,601 and $425,800.
The amount capital gains tax payable is however the capital gains itself multiplied by the percentage applicable of 15% not the entire taxable income since that consisted of other income from other sources aside from capital gains
capital gains tax=$2500*15%=$375
Answer: Its C, the rationale is that short-term capital gains are taxed at income tax rate
Step-by-step explanation:
$2500=$550 22%

the circumference of the cylinder is 4cm snf the height 9 cm. What is the curved surface area of the cylinder?
Answer: 326.73 is the precise answer
The requried curved surface area of the cylinder is approximately 35.927 square centimeters.
To find the curved surface area of a cylinder, we use the formula: C = 2πrh, where C is the circumference, π is a mathematical constant approximately equal to 3.14159, r is the radius of the base, and h is the height of the cylinder.
In this case, we are given the circumference C = 4 cm and the height h = 9 cm.
To find the radius, we can use the formula: C = 2πr. Rearranging the formula to solve for r:
r = C / (2π)
Substituting the given values:
r = 4 cm / (2 * 3.14159)
r ≈ 0.6366 cm
Now that we have the radius, we can calculate the curved surface area using the formula:
Curved surface area = 2πrh
Substituting the values:
Curved surface area = 2 * 3.14159 * 0.6366 cm * 9 cm
Curved surface area ≈ 35.927 cm²
Therefore, the curved surface area of the cylinder is approximately 35.9 square centimeters.

Answer:
(5,-1) and choice A
Step-by-step explanation:
The first step is to figure out where the two vectors are. Since one goes to (2,-3) and the other goes to (3,2), you already know that the only possible correct answer choices could be A and B, since C and D go to the wrong coordinates. Since the two vectors are originating from the same point and are not build on top of each other, you solve this by averaging them instead of adding head to tail. Using the pythagorean theorem, you know that the length of the new vector will be [tex]\sqrt{(3^2+2^2)+(3^2+2^2)}=\sqrt{26}[/tex]. The side lengths have length 5 and 1, since [tex]5^2+1^2=26[/tex]. Therefore, the coordinates of the new vector are (5,-1). Hope this helps!
A card is drawn at random from a standard pack of playing cards. Then a fair coin is flipped. What is the probability of selecting a 9 and the coin landing on heads?
Answer:
The probability is 1/26
Step-by-step explanation:
Here, we have two different sample spaces to work with and we want to calculate a compound probability.
Firstly in a deck of cards which contain a total of 52 cards, there are 4 cards labeled 9. Thus the probability of selecting a 9 is 4/52 = 1/13
Secondly in a flip of coin the probability of the coin landing on head is 1/2
Thus the probability of selecting a 9 and the coin landing on head = probability of selecting a nine * probability of the coins landing on head= 1/13 * 1/2 = 1/26

Answer:
false
Step-by-step explanation:
Based on the information provided we can say that this is false. Since it is a board game and no actual information regarding each players position in the game has been presented, then each player has an equal chance of winning each game. Therefore since there is a total of 3 players the percent chance of winning each game for each player is 33% (100 / 3 = 33)
