Hi there!
[tex]\large\boxed{P = 22 cm}[/tex]
To find the perimeter, we must find the length of the rectangle.
We know the area is 24, thus:
A = l × w
24 = l × 3
24/3 = l = 8 cm
Find the perimeter using the formula:
P = 2l + 2w
Plug in the solved length and width:
P = 2(8) + 2(3) = 16 + 6 = 22 cm.
Krissi has $14 in the bank and earns $8 a day. John has 35$ and earns $5 a day when will krissi have more money?
Answers
Answer: 8 days
Step-by-step explanation:
K=14+8x
J=35+5x
when K=J they will have the same amount
14+8x=35+5x
8x=21+5x
3x=21
x=7 days until they have the same amount- 8 days until she has more

Answer:
65 = 10 + 2x . . . equation for trip costx = 27.50 . . . cost of playStep-by-step explanation:
We are told that the costs add up this way:
trip cost = bus rental + 2 × (cost of play)
Given that ...
trip cost = $65bus rental = $10cost of play = xThe above equation can be rewritten as ...
65 = 10 + 2x . . . . . . the desired equation
__
Solving for x, we have ...
55 = 2x . . . . subtract 10
27.50 = x . . . . divide by 2
The cost of one play is $27.50.

The question is incomplete as the other triangles to make comparison from, are not given.
However, general information that could help you are as follows.
The given parameters show that we have to consider AA criterion for selecting similar triangles.
So, you need to check the [missing] given triangles, and pick any that have 10 and 145 (in that particular order) as measures of two of its angles.
Take for instance.
[tex]\triangle DE\ F[/tex]
Where
[tex]\angle D = 10[/tex]
[tex]\angle E = 145[/tex]
See that:
[tex]\angle D = 10[/tex] is similar to [tex]\angle A = 10[/tex]
[tex]\angle E = 145[/tex] is similar to [tex]\angle B = 145[/tex]
This means that:

Remember that "without replacement" means that the items are not returned to the sample space after they are chosen.
Recording
Write your answer in factorial notation.
Answers
Answer:
You can select all of them is 40320 ways.
Step-by-step explanation:
Number of arrangements of n elements:
The number of arrangements of n elements, that is, the number of ways in which n elements can be chosen without replacement, is given by:
[tex]A_{n} = n![/tex]
In this question:
8 elements, so:
[tex]A_{8} = 8! = 40320[/tex]
You can select all of them is 40320 ways.
Baseball statisticians studied how often triples (a certain event in a baseball game) occurred in professional games played between 1947 and 2017. A 98 percent confidence interval to estimate the slope of the linear regression line relating the year, x, and the mean number of triples per game, y, yielded (−0.006,−0.002). A check shows that the conditions necessary for inference for the slope of the regression line are met.
Based on the confidence interval, which of the following claims is supported?
A. The mean number of triples per game is between 0.002 and 0.006.
B. The number of triples per game has increased, on average, per year.
C. There is no linear relationship between the mean number of triples per game and year.
D. There is a negative linear relationship between the mean number of triples per game and year.
E. A conclusion cannot be made about the relationship between year and mean number of triples per game because the values are close to 0.
Answers
Answer: D. There is a negative linear relationship between the mean number of triples per game and year.
Step-by-step explanation: This claim is supported by the interval. The interval contains plausible values for the slope of the linear regression line relating year and mean number of triples per game. Since all the values in the interval are negative, the interval supports the claim that increases in the year are associated with decreases in the mean number of triples per game.

When a new highway is formed, the smoothness of the surface must be verified. A contractor is making a bid for this job and has a truck with the relevant detector. This detector must meet minimum standards for detecting irregularities in the road surface. If there is a roadway irregularity, there is a probability of 0.99 the detector will detect it. If there is no irregularity, there is a 0.06 probability detector will identify it as irregular (a false positive). It is known through experience that 3 miles out of 100 miles actually contain irregularities.
a. What is the probability the detector will identify a random mile of roadway as irregular? Give your answer to four decimal places.
b. Given a randomly selected miles has been identified as irregular by the detector, what is the probability it actually is irregular? Give your answer to four decimal places.
Answers
Answer:
a) 0.0879 = 8.79% probability the detector will identify a random mile of roadway as irregular.
b) 0.3379 = 33.79% probability it actually is irregular
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
a. What is the probability the detector will identify a random mile of roadway as irregular?
99% of 3%(it is irregular).
6% of 97%(false positive). So
[tex]p = 0.99*0.03 + 0.06*0.97 = 0.0879[/tex]
0.0879 = 8.79% probability the detector will identify a random mile of roadway as irregular.
b. Given a randomly selected miles has been identified as irregular by the detector, what is the probability it actually is irregular? Give your answer to four decimal places.
Conditional probability:
Event A: Identified as irregular
Event B: It is irregular.
0.0879 = 8.79% probability the detector will identify a random mile of roadway as irregular, which means that [tex]P(A) = 0.0879[/tex]
99% of 3% arre irregulars identified as, which means that [tex]P(A \cap B) = 0.03*0.99 = 0.0297[/tex]
The desired probability is:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0297}{0.0879} = 0.3379[/tex]
0.3379 = 33.79% probability it actually is irregular

Compound X is made up of two parts A and one part B. The mass of compound X is 45, and A has twice the mass of B. Which two equations would you solve to find the individual masses of A and B?
Answers
Answer:
[tex]A = 2B[/tex]
[tex]A + B = 25[/tex]
Step-by-step explanation:
Given
The first statement implies that:
[tex]X = A + B[/tex] i.e the components of X
Reading further, we have:
[tex]X = 45[/tex] ---- The mass of X
[tex]A = 2B[/tex] --- The relationship between [tex]A\ and\ B[/tex]
Required
Two equations to represent the scenario
The two equations are:
[tex]A = 2B[/tex] --- The relationship between [tex]A\ and\ B[/tex]
[tex]X = A + B[/tex] i.e the components of X
Substitute 25 for X in the second equation
[tex]25 = A + B[/tex]
[tex]A + B = 25[/tex]
So, the equations are:
[tex]A = 2B[/tex]
[tex]A + B = 25[/tex]
