Answer:

(a) 12.5%

(b) 20%

(c) 96th

Step-by-step explanation:

Let X denote the results of the 2018 SAT math exam.

It is provided that the mean of exam was, μ = 531 and standard deviation of σ  114.

Assume that X follows a normal distribution.

(a)

Compute the probability of test takers who scored lower than 400 on the math SAT as follows:

[tex]P(X<400)=P(\frac{X-\mu}{\sigma}<\frac{400-531}{114})[/tex]

                   [tex]=P(Z<-1.15)\\\\=0.12507\\\\\approx 0.125[/tex]

Thus, the percentage of test takers who scored lower than 400 on the math SAT is 12.5%.

(b)

Compute the probability of test takers who scored between 600 and 700 points as follows:

[tex]P(600<X<700)=P(\frac{600-531}{114}<\frac{X-\mu}{\sigma}<\frac{700-531}{114})[/tex]

                             [tex]=P(0.61<Z<1.48)\\\\=P(Z<1.48)-P(Z<0.61)\\\\=0.93056-0.72907\\\\=0.20149\\\\\approx 0.20[/tex]

Thus, the percentage of test takers who scored between 600 and 700 points is 20%.

(c)

Compute the value of P (Z < 725) as follows:

[tex]P(X<725)=P(\frac{X-\mu}{\sigma}<\frac{725-531}{114})[/tex]

                   [tex]=P(Z<1.70)\\\\=0.95543\\\\\approx 0.96[/tex]

Thus, a student who scores 725 has a 96th percentile rank.

Answer:

[tex]2.\ \ (4,6)[/tex]

[tex]4.\ \ (0,0)[/tex]

[tex]5.\ \ (2\frac{1}{2},3\frac{3}{4})[/tex]

Step-by-step explanation:

Given

[tex]y = 1\frac{1}{2}x[/tex]

Required

Determine if the given points is on the graph

First,, we rewrite [tex]y = 1\frac{1}{2}x[/tex] as

[tex]y = \frac{3}{2}x[/tex]

[tex]1.\ \ (1\frac{1}{2},1)[/tex]

This can be interpreted as:

[tex]x = 1\frac{1}{2}[/tex]

[tex]y = 1[/tex]

Substitute [tex]x = 1\frac{1}{2}[/tex]

[tex]y = \frac{3}{2} * 1\frac{1}{2}[/tex]

[tex]y = \frac{3}{2} * \frac{3}{2}[/tex]

[tex]y = \frac{9}{4}[/tex]

This isn't equal to the given value of y.

Hence: [tex](1\frac{1}{2},1)[/tex] is not a point on the graph

[tex]2.\ \ (4,6)[/tex]

Here,

[tex]x = 4[/tex]

[tex]y = 6[/tex]

Substitute [tex]x = 4[/tex]

[tex]y = \frac{3}{2} * 4[/tex]

[tex]y = \frac{3 * 4}{2}[/tex]

[tex]y = \frac{12}{2}[/tex]

[tex]y = 6[/tex]

This point is on the graph

[tex]3.\ \ (18,12)[/tex]

Here,

[tex]x = 18[/tex]

[tex]y = 12[/tex]

Substitute [tex]x = 18[/tex]

[tex]y = \frac{3}{2} * 18[/tex]

[tex]y = \frac{3 * 18}{2}[/tex]

[tex]y = \frac{54}{2}[/tex]

[tex]y = 27[/tex]

This isn't equal to the given value of y.

Hence: [tex](18,12)[/tex] is not a point on the graph

[tex]4.\ \ (0,0)[/tex]

Here, we have

[tex]x = 0[/tex]

[tex]y = 0[/tex]

Substitute [tex]x = 0[/tex]

[tex]y = \frac{3}{2} * 0[/tex]

[tex]y = 0[/tex]

Hence:

This point is on the graph

[tex]5.\ \ (2\frac{1}{2},3\frac{3}{4})[/tex]

Here

[tex]x =2\frac{1}{2}[/tex]

[tex]y = 3\frac{3}{4}[/tex]

Substitute [tex]x =2\frac{1}{2}[/tex]

[tex]y = \frac{3}{2} * 2\frac{1}{2}[/tex]

[tex]y = \frac{3}{2} * \frac{5}{2}[/tex]

[tex]y = \frac{15}{4}[/tex]

[tex]y = 3\frac{3}{4}[/tex]

Hence:

This point is on the graph

Answer:

800(1 + r)³ + 300(1 + r)² + 625(1 + r)

Step-by-step explanation:

At the beginning of the first year $800 is deposited.

At the end of the first year the amount of money in account = $800 × growth factor = 800(1 + r)

At the beginning of the second year, $300 is deposited, the money in account = 800(1 + r) + 300

At the end of the second year the amount of money in account is multiplied by growth factor. = [800(1 + r) + 300] × 1 + r = 800(1 + r)² + 300(1 + r)

At the beginning of the third year, $625 is deposited, the money in account = 800(1 + r)² + 300(1 + r) + 625

At the end of third year the money = [800(1 + r)² + 300(1 + r) + 625] × 1 + r = 800(1 + r)³ + 300(1 + r)² + 625(1 + r)

Answer:

(A) 0.6

(B) 0.1

Step-by-step explanation:

(A) Find the probability that NO family member chooses the same exit door.

Now, if no family member chooses the same exit door with another, it means that each person chooses a separate door. If each person chooses a separate door, then 6 out of 10 doors are chosen!

This translates to 6/10 which is = 0.6

So the probability that each family member has a door to him or herself is 0.6

(B) Find the probability that EVERY family member chooses the same exit door.

In this case, the number of persons (family members) does not really count. The focal point of the question is that everybody chooses the same door (and will use the same door). This means that only 1 door out of 10, will be chosen AND the probability that only one door out of 10 will be chosen is

1/10 = 0.1

Answer:

37.5 (G)

Step-by-step explanation:

Set up a proportion:

[tex] \frac{40}{100} = \frac{15}{x} [/tex]

Next cross multiply

[tex](15)(100) = (40)(x)[/tex]

[tex]1500 = 40x[/tex]

Lastly solve for x by dividing both sides by 40

[tex]\frac{1500}{40} = \frac{40x}{40} [/tex]

[tex]x = 37.5[/tex]

Answer:20+4√17

Step-by-step explanation:

2 of 3 sides are 16 and 4 units . The angle between them is 90 degrees.

So we can find the length of the third side using Pitagor theorem.

c= SQRT( 16²+4²)= sqrt (256+16)= sqrt (272)

So the perimeter of the shaded triangle is equal to

P= 4+16+sqrt(272)=20+4√17

The radical expressions for the perimeter of the shaded triangle is  20 + 4√17

In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.

We have a rectangle shown in the picture with dimensions.

Using Pythagoras theorem;

The inclined length = √(4²+16²) = √272 = 4√17

The perimeter of the shaded region = 16 + 4 + 4√17

Perimeter = 20 + 4√17

Thus, the radical expressions for the perimeter of the shaded triangle is  20 + 4√17

Answer:

The p-value of the test is 0.1314.

Step-by-step explanation:

In this case we need to test the claim made by a medical school that more than 28% of its students plan to go into general practice.

The hypothesis can be defined as follows:  

H₀: The proportion of students planning to go to general practice is 28%, i.e. p = 0.28.  

Hₐ: The proportion of students planning to go to general practice is more than 28%, i.e. p > 0.28.

The information provided is:  

 n = 130

[tex]\hat p=0.32[/tex]

Compute the test statistic value as follows:  

 [tex]z=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

    [tex]=\frac{0.32-0.28}{\sqrt{\frac{0.28(1-0.28)}{130}}}\\\\=1.12[/tex]

The test statistic value is 1.12.  

Compute the p-value as follows:  

 [tex]p-value=P(Z>1.12)\\[/tex]

                 [tex]=1-P(Z<1.12)\\\\=1-0.86864\\\\=0.13136\\\\\approx 0.1314[/tex]

The p-value of the test is 0.1314.

Answer:

There are 3 runs above and below the sample mean

Step-by-step explanation:

From  the given information; we have a table that can be computed as:

Observations              1      2       3      4     5     6

Number of defects     10     18    13    15     9     12

If we sort the order in ascending order; we have:

Observations              5      1       6      3     4     2

Number of defects     9     10    12    13     15     18

The median is the  middle number; here the integers are even :

Thus, the median is  (12 + 13)/2 = 12.5

We need to make counts from the table given above to determine if they are below or above the median

Observations              1      2       3      4     5     6

Number of defects     10     18    13    15     9     12

Above(A) /Below (B)    B     A       A     A    B      B

To count for the number of runs from the  beginning and when there is a change of runs from A to B; we have:  

Observations              1      2       3      4     5     6

Number of defects     10     18    13    15     9     12

Above(A) /Below (B)    B     A       A     A    B      B

Runs                             1        2      -      -      3      -

Therefore, from the analysis, there are 3 runs above and below the sample mean

The median element of a dataset is the middle element of the dataset.

There are 3 runs above and below the sample median

The information is given as:

Observations  1      2       3      4     5     6

Defects           10     18    13    15     9     12

In ascending order, the information is represented as:

Defects           9   10   12   13   15   18

Observations  5    1     6    3     4    2

The total number of observations is:

[tex]\mathbf{n = 5 + 1 + 6 + 3+ 4 + 2}[/tex]

[tex]\mathbf{n = 21}[/tex]

The median element is calculated as:

[tex]\mathbf{Median = \frac{n + 1}{2}th}[/tex]

Substitute 21 for n

[tex]\mathbf{Median = \frac{21 + 1}{2}th}[/tex]

[tex]\mathbf{Median = \frac{22}{2}th}[/tex]

[tex]\mathbf{Median = 11th}[/tex]

The 11th element is 12.

So, the median is:

[tex]\mathbf{Median = 12}[/tex]

Considering the given information;

Observations  1      2       3      4     5     6

Defects           10     18    13    15     9     12

The defects greater than the median (i.e. 12) are above (A) the median, while the defects less than the median are below (B)

So, we have:

Observations  1      2       3      4     5     6

Defects           10     18    13    15     9     12

Status               B     A       A     A    B      -

Next, we take a count of the number of times the status changes, i.e. from B to A, from A to B, from A or B to -

The count is 3.

Hence, there are 3 runs above and below the sample median

Answer:

The 80th percentile of the distribution is 1,490.01 grams

Step-by-step explanation:

Here, we want to find the 80% of the distribution

80% means 80/100 = 0.8

We need to get the z-score equivalent to 80th percentile;

This is equal to 0.842

Mathematically;

z-score = (x - mean)/SD

we want to calculate x here;

0.842 = (x - 1400.48)/(106.33)

106.33(0.842) + 1400.48 = x

x = 1,490.00986 which is 1,490.01 grams to 2 decimal places
