In the figure, TS = 8, SR = 4, and QR = 2, what is the length of PQ?
Answer:
d. 22
Step-by-step explanation:
(PQ + QR) × QR = (TS + SR) × SR => two secants intersecting theorem
PQ = ?
QR = 2
TS = 8
SR = 4
Plug in the values
(PQ + 2) × 2 = (8 + 4) × 4
2PQ + 4 = 12 × 4
2PQ + 4 = 48
2PQ + 4 - 4 = 48 - 4
2PQ = 44
2PQ/2 = 44/2
PQ = 22

ent clock.
5. My hour hand is between the 5 and the 6.
My minute hand is pointing to the 4.
What time do I show?
Answer:
5:20
Step-by-step explanation:
When working with the min hand
Starting from 12, each number of a clock adds an additional 5 mins until you reach the 12, where it starts at 0 again. So
1 = :05
2= :10
3 =:15
4 = :20
...and so on
When its 5:00, the hour hand is on the 5. As it moves towards 6:00, the hour hand will start to gradually get pulled towards the 6 until it becomes 6:00, where it will finally reach the 6.

According to a human modeling project, the distribution of foot lengths of 16- to 17-year-old boys is approximately Normal with a mean of 25.5 centimeters and a standard deviation of 1.4 centimeters. Suppose a shoe store stocks shoes in men's sizes 7 through 12. These shoes will fit men with feet that are 24.6 to 28.8 centimeters long. What percentage of boys aged 16 to 17 will not be able find shoes that fit in this store?
Answer:
27.02% of boys aged 16 to 17 will not be able find shoes that fit in this store
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions 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.
Mean of 25.5 centimeters and a standard deviation of 1.4 centimeters.
This means that [tex]\mu = 25.5, \sigma = 1.4[/tex]
These shoes will fit men with feet that are 24.6 to 28.8 centimeters long. What percentage of boys aged 16 to 17 will not be able find shoes that fit in this store?
Less than 24.6:
The proportion is the pvalue of Z when X = 24.6. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{24.6 - 25.5}{1.4}[/tex]
[tex]Z = -0.64[/tex]
[tex]Z = -0.64[/tex] has a pvalue of 0.2611
More than 28.8:
The proportion is 1 subtracted by the pvalue of Z when X = 28.8. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{28.8 - 25.5}{1.4}[/tex]
[tex]Z = 2.36[/tex]
[tex]Z = 2.36[/tex] has a pvalue of 0.9909
1 - 0.9909 = 0.0091
0.2611 + 0.0091 = 0.2702
0.2702*100% = 27.02%
27.02% of boys aged 16 to 17 will not be able find shoes that fit in this store

The difference between a number and 3 is no more than 2
Answer:
Any number 5 and below
Step-by-step explanation:
We are given the expression that the difference between a number and 3 is no more than 2. Break down the expression and spot the key word of "difference," therefore meaning that the unknown number "x" and 3 is equal or less than 2. We can create the algebraic expression of x - 3, now since the answer must equal 2 or below 2, we can create the inequality :
x - 3 ≤ 2
Now the only numbers that are allowed to be inputted here is 5 and below.
The solution to the inequality "the difference between a number and 3 is no more than 2" is x ≤ 5 or x ≥ 1.
Let us denote the number as "x," we can express the given statement as an inequality:
|x - 3| ≤ 2
This inequality states that the absolute value of the difference between x and 3 is less than or equal to 2.
If x - 3 ≥ 0 (x ≥ 3)
In this case, the absolute value can be removed:
x - 3 ≤ 2
x ≤ 2 + 3
x ≤ 5
and if x - 3 < 0 (x < 3)
The absolute value becomes negative:
-(x - 3) ≤ 2
x + 3 ≤ 2
x ≤ 2 - 3
x ≤ -1
x ≥ 1
Combining the results from both cases, we have:
x ≤ 5 or x ≥ 1
Therefore, the solution to the inequality "the difference between a number and 3 is no more than 2" is x ≤ 5 or x ≥ 1.

Step-by-step explanation:
Given the function g(x)= -x^2 + x + 5, determine the average rate of change of the function over the interval -4 ≤ x ≤ 3.
Answer:
The average rate of change is 2.
Step-by-step explanation:
We are given the function:
[tex]g(x)=-x^2+x+5[/tex]
And we want to find the average rate of change over the interval:
[tex]-4\leq x\leq 3[/tex]
The average rate of change is synonymous with the slope. So, we will evaluate the function at its endpoints and find the slope between them.
Our first endpoint is given by:
[tex]g(-4)=-(-4)^2+(-4)+5=-15[/tex]
And our second endpoint is given by:
[tex]g(3)=-(3)^2+(3)+5=-1[/tex]
This gives us two points (-4, -15) and (3, -1). The average rate of change will be the slope between them. Thus:
[tex]\displaystyle ARC=\frac{-1-(-15)}{3-(-4)}=\frac{14}{7}=2[/tex]
The average rate of change is 2.
Qantas shares pay a yearly return of 9% while Telstra shares pay 11%. John invests
$1500 more on Telstra shares than on Qantas shares, and his total yearly earnings from
the two investments is $1475. How much did he invest in Qantas shares?
Answer:
John invested $6550 into Qantas
Step-by-step explanation:
Let's mark his investment into Qantas as x. We can rewrite the problem statement as:
(x+$1500) * 0.11 + x * 0.09 = $1475
0.11x + 0.11 * $1500 + 0.09x = $1475
0.2x + $165 = $1475
0.2x = $1310
x = $6550

At a party, the ratio of chocolate cupcakes to vanilla cupcakes is 4 to 3. If there are 24 chocolate cupcakes, how many vanilla cupcakes are at the party?
Answer:
8
Step-by-step explanation:
24 dividing by 3 equals 8.
The number of vanilla cupcakes at the party will be 8.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that at a party, the ratio of chocolate cupcakes to vanilla cupcakes is 4 to 3. If there are 24 chocolate cupcakes.
The number of cupcakes will be calculated as:-
4 / 3 = 24 / V
V = ( 24 x 3 ) / 4
V = 18
Hence, the quantity of vanilla cups is 18.

Blank 1:
Answer:
0.367 = 36.7% probability that the student gets fewer than 2 questions correct
Step-by-step explanation:
For each question, there are only two possible outcomes. Either he guesses the correct answer, or he does not. The probability of guessing the correct answer on a question is independent of any other question. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
8 questions on it
This means that [tex]n = 8[/tex]
4 choices.
One of them is correct, which means that [tex]\pi = \frac{1}{4} = 0.25[/tex]
What is the probability that the student gets fewer than 2 questions correct?
This is
[tex]P(X < 2) = P(X = 0) + P(X = 1)[/tex]
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{8,0}.(0.25)^{0}.(0.75)^{8} = 0.1[/tex]
[tex]P(X = 1) = C_{8,1}.(0.25)^{1}.(0.75)^{7} = 0.267[/tex]
[tex]P(X < 2) = P(X = 0) + P(X = 1) = 0.1 + 0.267 = 0.367[/tex]

Now, solve:
first, multiply the first equation by 2
2x + y = 12 --> 4x + 2y = 24

Find the height of this cone using the Pythagorean Theorem. 8 cm h = [?] cm 8 cm Enter
Answer:
Step-by-step explanation:
The height of the cone base diameter of 8 cm and the slant height is 8 cm is 4√3 cm.
Given is a cone with base diameter of 8 cm and the slant height is 8 cm, we need to find the height of the cone by using Pythagorean Theorem.
To find the height of the cone using the Pythagorean Theorem, we can consider the slant height as the hypotenuse, the radius as one side, and the height as the other side.
Let's denote the radius of the cone as r and the height of the cone as h.
According to the given information, the base diameter of the cone is 8 cm, which means the radius is half of that, so r = 8 cm / 2 = 4 cm.
Now, using the Pythagorean Theorem, we have:
r² + h² = slant height²
Substituting the given values, we get:
4² + h² = 8²
16 + h² = 64
h² = 64 - 16
h² = 48
Taking the square root of both sides, we find:
h = √48
Simplifying the square root, we get:
h = √(16 x 3)
h = √16 x √3
h = 4√3 cm
Therefore, the height of the cone is 4√3 cm.
