Georgia has 322 beads. She buys 38 more beads. She will use a 120 beats to make bracelets and use the rest of the beads to make necklaces. Each necklace has 9 beads. What is the greatest number of necklacea georgia can make?
Answers
Applying mathematical operations, the greatest number of necklaces Georgia can make is 26.
How the mathematical operations are applied:The total number of beads available for making bracelets and necklaces is an addition operation between the beginning inventory of beads and the additional units purchased.
A subtraction operation is performed to determine the remainder after making bracelets.
Finally, a division operation determines the greatest number of necklaces to make.
The beginning inventory of beads = 322
The units purchased = 38 beads
The total number of beads that Georgia has = 360 (322 + 38)
The number of beads required to make bracelets = 120
The remainder after making bracelets = 240 (360 - 120)
The number of beads required for each necklace = 9
The greatest number of necklaces Georgia can make = 26 (240 ÷ 9)

If a sample of 6 keyboards is randomly selected, what is the probability that at least 5 of these will have a mechanical defect
Answers
Answer:
0.1978 is the probability that at least 5 keyboards will have mechanical defect.
Step-by-step explanation:
Solution:
Given:
A repair facility has 25 failed keyboards.
10 keyboards have electrical defect.
15 of which have mechanical defect.
Randomly selected keyboard= 6
The set of A is the set of keyboards with electrical defect.
And the set of B is set of keyboards with mechanical defect.

Solve, for 0 ≤ x < 360°, the equation
5 sinx - 5 cosx = 2
Answers
In response to the query, x is equal to 60°, 120°, 240°, and 300°. These four options are the answer to the equation.
What does equation mean in its entirety?A mathematical equation is a statement that two amount or values are equal, such as 6 x 4 = 12 x 2. 2. A noun that counts. An equation is applied when several or more factors must be considered jointly in order to understand or explain the whole situation.
This equation can be solved using the trigonometric identity:
\(sinx = \sqrt{ (1 - cos^2x)}\)
This identity can be used as a substitution in the equation:
5 sinx - 5 cosx = 2
5 \(\sqrt{(1 - cos^2x) }\) - 5 cosx = 2
5 sqrt\((1 - cos^2x)\)) = 7 + 5 cosx
Squaring both sides:
25(\(1 - cos^2x\)) = 49 + 70 cosx + 25 \(cos^2x\)
25 - 25 \(cos^2x\) = 49 + 70 cosx + 25 \(cos^2x\)
0 = 74 + 45 cosx
45 cosx = -74
cosx = -74/45 = -2/3
The inverted cosine function can be used to determine that x = cos-1(-2/3). x must be within the range of 0° to 360°, hence x must be 300°.
5 sin - 5 cos - 5(-1/2) = 5 sqrt(3)/2 + 5/2 = 2 + 2.5 = 2.5
Since the left side of the equation is not equal to 2, x = 300° is not a solution to the equation.
We can repeat this process for the other solutions to the equation:
x = 60°, x = 120°, x = 240°, and x = 300°
These are the four solutions to the equation for 0° <= x < 360°.

In a normal distribution with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:
\(Z = \frac{X - \mu}{\sigma}\)
It 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, which is the percentile of X.Question 3:
The mean is of 73 inches, hence \(\mu = 73\).The standard deviation is of 3 inches, hence \(\sigma = 3\).Item a:
The 40th percentile is X when Z has a p-value of 0.4, so X when Z = -0.253.
\(Z = \frac{X - \mu}{\sigma}\)
\(-0.253 = \frac{X - 73}{3}\)
\(X - 73 = -0.253(3)\)
\(X = 72.2\)
The 40th percentile of the height of Dinaric Alps distribution for men is of 72.2 inches.
Item b:
The minimum height is the 100 - 10 = 90th percentile is X when Z has a p-value of 0.9, so X when Z = 1.28.
\(Z = \frac{X - \mu}{\sigma}\)
\(1.28 = \frac{X - 73}{3}\)
\(X - 73 = 1.28(3)\)
\(X = 76.84\)
The minimum height of man in the Dinaric Alps that would place him in the top 10% of all heights is of 76.84 inches.
Question 4:
The mean score is of 75, hence \(\mu = 75\).The standard deviation is of 5, hence \(\sigma = 5\).
Item a:
The 25th percentile is X when Z has a p-value of 0.25, so X when Z = -0.675.
\(Z = \frac{X - \mu}{\sigma}\)
\(-0.675 = \frac{X - 75}{5}\)
\(X - 75 = -0.675(5)\)
\(X = 71.6\)
The 25th percentile for the math scores was of 71.6 inches.
Item b:
The 75th percentile is X when Z has a p-value of 0.25, so X when Z = 0.675.
\(Z = \frac{X - \mu}{\sigma}\)
\(0.675 = \frac{X - 75}{5}\)
\(X - 75 = 0.675(5)\)

Tasha has hit the ball 9 times out of 10 attempts. Which player has a ratio that means they have a better batting average? Tasha, because she has the lowest ratio since 0.9 > 0.8
B) Tasha, because she has the highest ratio since 27 over 30 is greater than 24 over 30
C) Jana, because she has the lowest ratio since 0.9 > 0.8
D) Jana, because she has the highest ratio since 27 over 30 is greater than 24 over 30

A 18 B C 20 30 D 48 What is the surface area, in square inches, of the rectangular prism formed by folding the net below? 8 in. 23 in. 8 in. 36 in.
Answers
The number of red tiles in the box given the chance ratio of red to blue tiles is 18. The surface area of the rectangular prism is 2600 square inches.
Number of red tiles = x
Number of blue tiles = 12 + x
Total tiles = x + 12 + x
= 12 + 2x
Ratio of red = 3
Ratio of blue = 5
Total ratio = 3 + 5 = 8
Number of red tiles = 3 / 8 × 12+2x
x = 3(12 + 2x) / 8
x = (36 + 6x) / 8
8x = 36 + 6x
8x - 6x = 36
2x = 36
x = 36/2
x = 18 tiles
Therefore, The number of red tiles in the box given the chance ratio of red to blue tiles is 18.
b) To find the surface area of the rectangular prism, we need to find the area of each of its faces and add them together. Looking at the net, we see that there are three pairs of identical rectangles: the top and bottom faces, the front and back faces, and the left and right faces. Each of these rectangles has dimensions of 23 inches by 8 inches.
Therefore, the surface area of the rectangular prism is:
=2 * (23 in. * 8 in.) (top and bottom faces)
=2 * (36 in. * 8 in.) (front and back faces)
=2 * (23 in. * 36 in.) (left and right faces)
= 368 + 576 + 1656
= 2600 square inches
Therefore, the surface area of the rectangular prism is 2600 square inches.

The component form of the following vectors is Option A. V = (38.3, 32.1).
To find the component form of a vector given its magnitude and direction angle, we can use trigonometry.
The component form of a vector in two dimensions is represented as (x, y), where x is the horizontal component and y is the vertical component.
In this case, the magnitude of the vector is given as 50, and the direction angle θ is 50°. We can use this information to calculate the horizontal and vertical components.
The horizontal component (x) can be found using the formula x = magnitude * cos(θ), and the vertical component (y) can be found using y = magnitude * sin(θ).
Let's calculate the components:
x = 50 * cos(50°) ≈ 38.3
y = 50 * sin(50°) ≈ 32.1
Rounding the answers to the nearest tenth, we get the component form of the vector V as (38.3, 32.1).
Therefore, the correct answer is A. V = (38.3, 32.1).

4ml = 2ml + 2ml
And we know that, in every 2 ml of medicine, there are 5mg.
Then if we have two times 2ml of medicine, we have two times 5mg.
This is:
2*5mg = 10mg

Find the probability of at least 6 failures in 7 trials of a binomial experiment in which the probability of success in any one trial is 80%.
Round to the nearest tenth of a percent
Answers
Rounding to the nearest tenth of a percent, the probability of at least 6 failures in 7 trials with a success probability of 80% is 0.336 or 33.6%.
To find the probability of at least 6 failures in 7 trials of a binomial experiment with a success probability of 80%, we can use the binomial probability formula:
P(X ≥ 6) = 1 - P(X < 6)
where X is the number of failures in 7 trials and P(X < 6) is the probability of having less than 6 failures.
The probability of exactly x failures in 7 trials is given by the formula:
P(X = x) = (7 choose x) * 0.2^x * 0.8^(7-x)
where (7 choose x) represents the number of ways to choose x failures from 7 trials.
To find P(X < 6), we need to calculate the probability of having 0, 1, 2, 3, 4, or 5 failures:
P(X < 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)
Using the formula above, we can calculate each probability and then sum them up.
P(X < 6) = 0.0008 + 0.0072 + 0.032 + 0.089 + 0.209 + 0.327
P(X < 6) = 0.664
Therefore, the probability of at least 6 failures in 7 trials is:
P(X ≥ 6) = 1 - P(X < 6)
P(X ≥ 6) = 1 - 0.664
P(X ≥ 6) = 0.336

Answer:
the correct choice is marked
Step-by-step explanation:
The lengths will form a right triangle if the squares of the two shortest legs total the square of the longest. The square of a root is the number under the radical, so you're looking to see if the two smallest numbers under the radicals total the largest number under the radical.
A: 22 +88 = 110 . . . . . a right triangle
B: 66 +99 = 165 ≠ 176 . . . . an obtuse triangle
C: 22 +110 = 132 ≠ 121 . . . . an acute triangle
D: 66 +77 = 143 ≠ 154 . . . . an obtuse triangle

Additional comment
The largest angle is opposite the longest side. If the longest side is too long for the triangle to be a right triangle, then the opposite angle is larger than 90°, and the triangle is obtuse. If the longest side is too short for a right triangle, then the triangle is acute.

such that
AB:BD = 1:2
AC:CD= 7:2
Find AB:BC:CD
Answers
Answer:
7 + 2 = 9, so AC = 7/9 and CD = 2/9
1 + 2 = 3, so AB = 1/3 = 3/9 and
BD = 2/3 = 6/9
AB + BC = AC
3/9 + BC = 7/9, so BC = 4/9
AB:BC:CD = (3/9):(4/9):(2/9) = 3:4:2
