The correct estimate is 2000. Thus, Lenore’s estimate is not reasonable

Estimation is a method used for calculating the approximate value of a quantity (just to get a 'rough answer')

In estimation 1, 2,3, and 4 are rounded down while 5, 6, 7, 8 and 9 are rounded up.

Given:  51 x 37

In order round each factor to the nearest ten to estimate the reduction

51 will be rounded down to 50 (because of the 1 after the 5 in 51)

37 will be rounded up to 40 (because of the 7 after the 3 in 37)

Thus, the estimate will be:

50 x 40 = 2000

Therefore, Lenore’s estimate is not reasonable because she rounded down 37 to 30

Answer:

See below

Step-by-step explanation:

From the graph , function 1 has a max value of   1 at  4,1

From the equation for function 2, its max occurs at x = - b/2a = - (2/(2*-1) = 1

   plugging in this value shows max value of   - 14     (1,-14)  

The required value of x is  135° in the given polygon. which is the correct answer would be an option (A).

A polygon is given in the figure

According to the given question, the required solution would be as:

Number of sides = 8

The required value of x is the equal to measure of one Interior angle in the given polygon.

Interior angles of a polygon = (sides - 2) × 180°

In this case, the number of sides is 8

Sum of Interior angles = (8 - 2) × 180

Sum of Interior angles = (6) × 180

Sum of Interior angles = 1080°

the measure of one Interior angle = 180°/8

the measure of one Interior angle = 135°

Thus, the required value of x is  135°.

4. pr/n + m = - 48

5.  p²/m - (np + r) = 10

6. p³/r² - (m + np) = 16

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The values are,

a = - 2, b = 3, c = - 12 and d = - 4

m = - 32, n = 2, p = - 8 and r = 4

Now,

Find the values of the expressions as;

1. bd/a + c

Substitute all the values, we get;

bd/a + c = (3 x - 4)/(-2) + (-12)

             = - 12/- 2 - 12

             = 6 - 12

             = - 6

2. ac/b - (a + d)

Substitute all the values, we get;

⇒ ac/b - (a + d) = - 2 x - 12 /3 - (- 2 - 4)

                    = 8 + 6

                    = 14

3. d³/a² - (c + b)

Substitute all the values, we get;

d³/a² - (c + b) = 3³/(-2)² - (-12 + 3)

                    = 27/4 + 9

                    = 63/4

4. pr/n + m = - 8 x 4 /2 + (-32)

                 = - 16 - 32

                 = - 48

5. p²/m - (np + r) = (-8)²/- 32 - (2 x - 8 + 4)

                         = - 64/32 - (- 16 + 4)

                          = - 2 + 12

                          = 10

6. p³/r² - (m + np) = (-8)³/4² - (- 32 + 2 x - 8)

                           = - 32 - (- 32 - 16)

                           = - 32 + 48

                           = 16

Thus, The values of the expression are;

The interval that represents the middle 95% of his commute times is [45 , 55]

What is standard deviation ?

In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.

The empirical rule states that the 95% of the sampled observations will fall within two standard deviations of the mean for a normally distributed population.

Where:

68% is the first standard deviation

95% is the second standard deviation about the mean

99.7% is the 3rd standard deviation about the mean.

Therefore. the middle 95% interval is calculated as:

CI = µ + 2 σ

   =  50 ± 2 (2.5)

   = 50 ± 5

  = [45 , 55]

c) Counting & Probability and Beth does not get Introduction to Geometry and Caleb gets Introduction to Algebra: 1/24 = 0.0417 = 4.17%.

A probability is obtained as the division of the number of desired outcomes by the number of total outcomes.

In this problem, the total number of outcomes is the arrangements of 4 elements, hence:

Total = 4! = 24.

For item a, we want Ann to get one book, and the remaining 3 books are arranged, hence the probability is of:

p = 3!/4! = 1/4 = 0.25 = 25%.

For item b, we want for Ann to get one book, Beth can get 2 of them, and the remaining 2 are arranged, hence the probability is of:

p = 2 x 2!/4! = 4/24 = 1/6 = 0.167 = 16.7%.

Answer:

a)  A = (1, 2),   A' = (3, 6)

b)  B' = (9, 3)

Step-by-step explanation:

From inspection of the given diagram:

   A = (1, 2)

   A' = (3, 6)

As the triangle has been enlarged by a scale factor of 3 and centre (0, 0), to find the coordinates of B' simply mulitply the coordinates of B by the scale factor:

   As B = (3, 1)

The dimension outside the frame is 11 inches long and 9 inches wide.

In the given question we have to find the outside dimensions of the frame.

In the given question, a picture 10 inches long by 8 inches wide has a frame whose area is one half the area of the picture.

The dimension of a picture is 10 inches long by 8 inches wide.

The area of the frame is one half i.e(1/2=0.5)to the area of the picture.

So the length of the frame is

=10+0.5+0.5

=11 inches

The width of the frame is

=8+0.5+0.5

=9 inches

Hence, the dimension outside the frame is 11 inches long and 9 inches wide.

0.2456 = 24.56%  probability of the mean IQ score of people in the sample is less than 99.

What is the Normal Probability Distribution?

The Normal (or Gaussian) distribution is the most common continuous probability distribution. The function calculates the likelihood that an event will occur between any two real number limits as the curve gets closer to zero on either side of the mean. The area beneath the normal curve is always one.

Problems of normal distributions can be solved using the z-score formula.

In a set with mean  and standard deviation, the z-score of a measure X is:

[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.

This is the P value of Z when X = 98.

[tex]z = \frac{x - \mu}{\sigma}[/tex]

z = (99 -100)/15

z = -0.066

z = -0.066 has a P value of 0.2456

Hence, 0.2456 = 24.56%  probability of the mean IQ score of people in the sample is less than 99.

According to the given confidence interval, the number of samples for this research is 1134.

Confidence interval

Confidence interval means the percentage of probability, or certainty, that the confidence interval would contain the true population parameter when you draw a random sample many times.

Given,

The state education commission wants to estimate the fraction of tenth grade students that have reading skills at or below the eighth grade level. In an earlier study, the population proportion was estimated to be 0.18.

Here we need to find the number of samples.

Here we know that the Confidence level=0.99,

So, the value of

=> 1−α=0.99,

Noe, the estimate of population proportion = 0.18,

So, the value of pˆ=0.19,

And the Allowable error = 0.03

Which is E=0.03

Now, the determined value of α is calculated as,

=> α = 1 − 0.99 = 0.18

Thus, the value of z will produce 99%confidence is,

=> zα / 2 = z 0.01/2

=> z0.005 = 2.575

=> (2.575)√(.18)(1-0.18)/√0.03

→ 4v = 7 - 7

→ v = 0/4

→ [ v = 0 ]

2) 3(u + 4) = 27, for u?

→ 3(u + 4) = 27

→ 3u + 12 = 27

→ 3u = 27 - 12

→ u = 15/3

→ [ u = 5 ]

3) -20 = 10(h + 5), for h?

→ -20 = 10(h + 5)

→ 10h + 50 = -20

→ 10h = -20 - 50

→ h = -70/10

→ [ h = -7 ]

4) -10 = (n - 52)/5, for n?
