Which one is it 2 or 4?

Answer:

Hope this helps!!!

Step-by-step explanation:

Reflecting around x=1 never touches the y coordinate, and the x coordinate transforms - what was the distance to x=1 becomes the distance on the other side. In other words, if a point were at x=π, it's distance to x=1 was π−1 so the new location is π−1 to the left of x=1, i.e. 1−(π−1)=2−π.

Answer:

hi! once you link the picture I will answer the problem.

Step-by-step explanation:

Answer: The distance between the library and the florist’s shop is the length of C⁢D¯. The endpoints of this line segment are C(3, 4) and D(3, -3). Because the x-coordinates of both points are the same (3), the length of C⁢D¯ can be found by subtracting the smaller y-coordinate from the greater y-coordinate: CD = 4 – (-3) = 4 + 3 = 7 units. The distance between the library and the florist’s shop is 7 blocks.

Answer:

With replacement, there are 1600 possible outcomes.

Without replacement, there are 1560 possible outcomes.

Step-by-step explanation:

Chosen with replacement:

State is chosen, then put back in the group, then another state can be chosen. In both cases, there will be 40 possible outcomes, as the first taken state is placed back. So

40*40 = 1600

With replacement, there are 1600 possible outcomes.

Chosen without replacement:

State and chosen and is not replaced.

So, for the second state, there will be only 39 possible outcomes.

40*39 = 1560

Without replacement, there are 1560 possible outcomes.

Answer:

Option d

Step-by-step explanation:

A quadrilateral can be constructed uniquely if the lengths of its four sides and a diagonal are given. A quadrilateral can be constructed uniquely if the lengths of its three sides and two diagonals are given. A quadrilateral can be constructed uniquely if its two adjacent sides and three angles are given.

So according to this, it could be option d. A rhombus with two acute angles and sides of length 12ft.

Hope it helps :)

Answer:

Step-by-step explanation:

We take ~p∧~q∨r to mean (~p∧~q)∨r because "and" normally has precedence over "or." The (~p∧~q) term will only come into play when both p and q are false. It will only affect the outcome if r is also false. This condition is the last line of the table.

Answer: 28 and 30

Step-by-step explanation:

Let the house numbers on the street be represented by n and n+2 sine they are consecutive even integers. Therefore,

n + (n + 2) = 58

2n + 2 = 58

2n = 58 - 2

2n = 56

n = 56/2

n = 28

Therefore the second number will be:

= n + 2

= 28 + 2

= 30

The numbers are 28 and 30

Answer:

31

Step-by-step explanation:

Given :-

And we need to find the value of AB .

Pythagoras Theorem :-

Using that ,

[tex]:\implies[/tex] h² = p² + b²

[tex]:\implies[/tex] h² = 36² + 15²

[tex]:\implies[/tex] h² = 1296 + 225

[tex]:\implies[/tex] h² = 1521

[tex]:\implies[/tex] h = 31

Hence the value of Hypotenuse is 31 .

Answer:

there is no profit there is loss because CP is greater than SP

Step-by-step explanation:

loss=CP-SP

=Rs480-Rs420

=Rs60

loss%=loss/cp*100%

=60/480*100%

=6000/480

=12.5%

Answer:

area = 186.984

Step-by-step explanation:

The 3 rectangular surfaces are simply L * W of each so

left surface = 5.5 * 6.2 = 34.1

right surface = 5.5 * 8.5 = 46.75

bottom surface = 5.5 * 9.8 = 53.9

The front and back are the same so

front = 1/2 base * heigth = 1/2 * 9.8 * 5.33 = 26.117

front + back = 2 * 26.117 = 52.234

total = sum them all up = 34.1 + 46.75 + 53.9 + 52.234 = 186.984

Answer:

0.4332 = 43.32% probability that the sample mean is between 21 and 22.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

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 z-score 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 p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

According to a report from a business intelligence company, smartphone owners are using an average of 22 apps per month.

This means that [tex]\mu = 22[/tex]

Standard deviation is 4:

This means that [tex]\sigma = 4[/tex]

Sample of 36:

This means that [tex]n = 36, s = \frac{4}{sqrt{36}}[/tex]

What is the probability that the sample mean is between 21 and 22?

This is the p-value of Z when X = 22 subtracted by the p-value of Z when X = 21.

X = 22

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{22 - 22}{\frac{4}{sqrt{36}}}[/tex]

[tex]Z = 0[/tex]

[tex]Z = 0[/tex] has a p-value of 0.5.

X = 21

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{21 - 22}{\frac{4}{sqrt{36}}}[/tex]

[tex]Z = -1.5[/tex]

[tex]Z = -1.5[/tex] has a p-value of 0.0668.

0.5 - 0.0668 = 0.4332

0.4332 = 43.32% probability that the sample mean is between 21 and 22.

Answer:

11/320

Step-by-step explanation:

the probability of a senior being chose first is 22 (seniors) divided my total number of students (80) is .275 percent.

multiplied by the probability of a sophomore being chosen 10/80 which equals .125.

multiply those together and you get your probability. 0.034375 or 11/320

Step-by-step explanation:

Angelo is making 9 dollars per hour but, loses 2 dollars due to the bus fee. So in math form that would be:

9x - 2

And the second part is Tom makes 8 dollars per hour but doesn't have to pay for bus fee. In math form that would be;

8x

So put that together that would be

9x - 2 = 8x
