The cumulative incidence of stroke in patients classified as hypertensive at baseline = 0.625

Step-by-step explanation:

The table properly drawn is that

Baseline - Not hypertensive

Free of stroke at 5 years | Stroke | Total

1000 | 50 | 1050

Baseline - Hypertensive

Free of stroke at 5 years | Stroke | Total

300 | 501 | 801

Compute the cumulative incidence of stroke in patients classified as hypertensive at baseline.

Number of patients classified as hypertensive at baseline = 801

number of stroke incidents amongst patients classified as hypertensive at baseline = 501

The cumulative incidence of stroke in patients classified as hypertensive at baseline = (501/801) = 0.625

Answer:

cost of paint set  =$19.5

cost of Sketchbook = $13

cost of brush =  $3..25

Step-by-step explanation:

Total money with Nate = $37.75

Let the cost of paint set be $x

As the  Sketchbook cost 2/3 the cost of the paint set

Thus cost of Sketchbook = $(2/3)x

Cost of brush is 1/4 of Sketchbook

Thus cost of brush = (1/4)*(2/3)x =$ 1/6x

Total cost of all the three item in terms of x  is

x + (2/3)x + ( 1/6)x

=>(6x+4x+x)/6 = 11x/6

Given that after money spent on buying all the three thing Nate has left $2

subtracting money spent on buying three things from total money is equal to $2

Mathematically it can be written as

$37.75 -  11x/6 = $2

=> $37.75  - $2  11x/6

=>$35.75 =  11x/6

=> $35.75*6 = 11 x

=> $214.5 = 11x

=> $214.5/11 = x  

=> x = 19.5

Thus,

cost of paint set  = x = $19.5

cost of Sketchbook = $(2/3)x =$(2/3)*19.5 = $13

cost of brush = $ 1/6x = $ (1/6)*19.5 = $3.25

Answer:

As E is right angle , CD is hypotenuse , and ED is perpendicular and CE is the base .

Thus sinC = Perpendicular/ Hypotenuse

sinC = ED/CD

sinC = 3/5

The sine of an angle in a right triangle is the ratio of the side opposite to

the angle to the hypotenuse side.

Reasons:

The given parameters of ΔCDE are;

∠E = 90°, DC = 5, CE = 4, ED = 3

Required: The ratio that represents the sine of ∠C

Solution:

Given that ∠E = 90° therefore;

ΔCDE is a right triangle

DC = The hypotenuse side = 5

ED = 3 = The side opposite ∠C

[tex]sin\angle C = \mathbf{\dfrac{Opposite \ leg \ length}{Hypotenuse \ length}}[/tex]

Therefore;

[tex]\underline{sin\angle C \ is \ \dfrac{3}{5}}[/tex]

Answer:

[tex]t=\frac{130-120}{\frac{40}{\sqrt{80}}}=2.236[/tex]    

Now we can find the degrees of freedom:

[tex]df=n-1=80-1=79[/tex]  

Now we can calculate the p value with the alternative hypothesis using the following probability:

[tex]p_v =P(t_{(79)}>2.236)=0.0141[/tex]  

Using a significance level of 0.01 or 1% we have enough evidence to FAIL to reject the null hypothesis and we can conclude that shoppers participating in the loyalty program NOT spent more on average than typical shopper at this significance level assumed

Step-by-step explanation:

Information given

[tex]\bar X=130[/tex] represent the sample mean

[tex]s=40[/tex] represent the sample standard deviation

[tex]n=80[/tex] sample size  

[tex]\mu_o =120[/tex] represent the value to verify

t would represent the statistic  

[tex]p_v[/tex] represent the p value

System of hypothesis

We want to verify if  shoppers participating in the loyalty program spent more on average than typical shoppers (120) , the system of hypothesis would be:  

Null hypothesis:[tex]\mu \leq 120[/tex]  

Alternative hypothesis:[tex]\mu > 120[/tex]  

The statistic for this case is given by:

Answer:

Inches

Step-by-step explanation:

the praying mantis is too small for the other units.

The length of a praying mantis would measure in inches.

It is defined as the numerical quantity that gives an idea about an object's weight length, width, and many more. It can be used to compare two objects.

We know feet, inches, yards, and miles are the unit of measuring the length.

We have an object that is a praying mantis. Usually, the mantis's length is about 3 to 4.5 inches.

We also know 1 foot = 12 inches

1 yard = 36 inches

1 mile = 63360 inches

As we can see the feet, yard, and mile are the units to measure the long length.

Thus, the length of a praying mantis would measure in inches.

Answer:

  126 in^2

Step-by-step explanation:

The surface area can be found from the surface area formula:

  SA = 2(LW +LH +WH)

I like to rearrange it slightly to ...

  SA = 2(LW +H(L +W))

For the given dimensions, the area is ...

  SA = 2(6·3 + 5(6 +3)) = 2(18 +45) = 126 . . . . square inches

Answer:

Step-by-step explanation:

Hello!

The variable of interest is:

X: motor skills of a sober subject.

n= 20

X[bar]= 37.1

S= 3.7

The claim is that the average score for all sober subjects is equal to 35.0, symbolically: μ= 35.0

The hypotheses are:

H₀: μ = 35.0

H₁: μ ≠ 35.0

α: 0.01

The statistic to use, assuming all conditions are met, is a one sample t- test

[tex]t= \frac{X[bar]-Mu}{\frac{S}{\sqrt{n} } } ~t_{n-1}[/tex]

[tex]t_{H_0}= \frac{37.1-35.0}{\frac{3.7}{\sqrt{20} } } = 2.34[/tex]

This test is two-tailed, meaning, the rejection region is divided in two and you'll reject the null hypothesis to low values of t or to high values of t:

[tex]t_{n-1;\alpha /2}= t_{19; 0.005}=-2.861[/tex]

[tex]t_{n-1;1-\alpha /2}= t_{19; 0.995}= 2.861[/tex]

The decision rule using this approach is:

If [tex]t_{H_0}[/tex] ≤ -2.861 or if [tex]t_{H_0}[/tex] ≥ 2.861, you reject the null hypothesis.

If -2.861 < [tex]t_{H_0}[/tex] < 2.861, you do not reject the null hypothesis.

The value is within the non rejection region, the decision is to not reject the null hypothesis.

I hope this helps!

Answer:

84 square inches

Step-by-step explanation:

First, separate this shape into two shapes you can easily find the area of. You can do this by turning it into a rectangle and a rhombus.

Say the rectangle has measurements of 5 by 6 inches. The area of that rectangle will be 30 square inches. Save this value to add on later.

The rhombus now has a height of 4 (because the side length 10 minus the side length 6 equals 4), and two bases by the values of 12 and 15. The area of a rhombus can be found with the equation:

a = 1/2(b1 + b2) x h

Simply plug in those values to find the area of the rhombus, 54. Now add the area of the rhombus and the area of the rectangle to get 84 square inches as your final area.

The radius is 5 cm

Step-by-step explanation:

The formula for the area of a circle is :  [tex]\p*radius^2[/tex]

To work out the length of the radius you would first need to divide the area of  78.5 cm by pi (pi=3.14), this gives you [tex]25cm^2\\[/tex]. This is because by dividing the area by pi we are isolating the value of the radius squared.

The final step is to work out the radius. You can do this by finding the square root of the radius squared which is 25, this gives you 5 cm. This means that the radius is 5 cm. This is because the square root is a number that when squared equals that number.

1) Divide 78.5 by pi.

[tex]78.5/\pi=25cm^2[/tex]

2) Find the square root of 25 cm squared.

[tex]\sqrt{25} =5 cm[/tex]

Answer:

1.56% probability that the student gets all three questions right

Step-by-step explanation:

For each question, there are only two possible outcomes. Either the student guesses the answer correctly, or he does not. The probability of the student guessing the answer of a question correctly is independent of other questions. So we use the binomial probability distribution 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.

Each question has 4 possible answers, one of which is correct.

So [tex]p = \frac{1}[4} = 0.25[/tex]

Three questions.

This means that [tex]n = 3[/tex]

What is the probability that the student gets all three questions right?

This is [tex]P(X = 3)[/tex]

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 3) = C_{3,3}.(0.25)^{3}.(0.75)^{0} = 0.0156[/tex]

1.56% probability that the student gets all three questions right

There are 7 rows of 9 people then there will be 63 people in all.

Multiplication refers to the product of two numbers or more than two numbers. It states the result when a number is taken times.

There are 7 rows of 9 people.

This means in each row, there are 9 people.

Then the number of people in 7 rows will be 7 multiplied by 9 i.e.,

[tex]7\times9=63[/tex]

So, the number of people will be 63.
