Answer:

y=2b+4s

Step-by-step explanation:

The value of ST is 8.

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side). Equations can be solved to find the value of an unknown variable representing an unknown quantity. If there is no 'equal to' symbol in the statement, it means it is not an equation. It will be considered as an expression.

Given:

ST=5x-7, RT=4x+9, RS=2x+7

So,

RS + ST = RT

2x +7  + 5x -7 = 4x+9

7x = 4x +9

3x= 9

x=3

So,

ST= 5x-7 = 5*3 -7= 15-7= 8

Answer:

C

Step-by-step explanation:

So we have a cylinder with a hole the shape of a rectangular prism through it.

Therefore, our total volume would be the cylinder minus the volume of the rectangular prism.

The volume of a cylinder is given by the formula:

[tex]V=\pi r^2h[/tex]

Use 3.14 for π, 10 for radius, and 15 for the height. Thus:

[tex]V=(3.14)(10)^2(15)\\V=4710[/tex]

So the volume of the cylinder is 4710 cubic feet.

Now, find the volume of the rectangular prism.

The formula for the volume of a rectangular prism is given by:

[tex]V=lwh[/tex]

The length is 5, width is 3, and height is 15. Thus:

[tex]V=(5)(3)(15)\\V=225[/tex]

So, the total volume is:

[tex]V_{\text{Total}}=V_{\text{Cylinder}}-V_{\text{Rectangle}}\\V_{\text{Total}}=4710-225=4485\text{ feet}^3[/tex]

Answer:

A)y ± [tex]t_{21}[/tex] ( 1.29 )

B) y ± 2.58

C ) yes

Step-by-step explanation:

standard error = 1.29 bushels

approximate width of 95% prediction interval for an individual can be represented as ;  [tex]y[/tex] ± [tex]t_{n-k-1}[/tex] ( SE )

[tex]t_{n-k-1} = critical value of t at n-k-1[/tex] degree of freedom

n = 26

k = 4

a) Approximate width of a 95% prediction interval for wheat yield

[tex]y[/tex] ± [tex]t_{n-k-1}[/tex] ( SE )

Insert the values into the equation

n - k -1 = 26 - 4 - 1 = 21

y ± [tex]t_{21}[/tex] ( 1.29 ) you can get the value of [tex]t_{21}[/tex] from the t table for 21 degrees at 0.05 significance level

Answer:

M = 1/18

Step-by-step explanation:

The slope is 1/18 mi/min, which means Sonia walks at a rate of 1 mile every 18 minutes.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

Given that, Sonia is walking 2.5 miles home from school.

She left at 4:00 pm and got home at 4:45 pm. She took 45 minutes to get there.

We can interpret the information as two points, the first one is (0,0) that represents the starting point. The second point is (45, 2.5), which represents the ending point when she arrived home. Let's graph these points and draw a line through them.

To find the slope, divide 2.5 miles by 45 minutes,

Thus, slope =2.5/45

m= 1/18 miles per minute

Therefore, the slope is 1/18 mi/min, which means Sonia walks at a rate of 1 mile every 18 minutes.

a parrallogram is a square of sorts, so just take the base times the height divided by two for the triangle portion than multiple by 2 to get rhe same answer back because those two triangles make a square

Answer:

1. 0.3

2. Relative frequency

Step-by-step explanation:

We would be calculating for p(A) which is the probability of A. With A being that public buildings would be found to be insulated with same materials that causes same issues

n = sample space of public buildings = 10

F = frequency = 3

P(A) = 3/10 = 0.3

Therefore 0.3 is the approximate probability of another building having same issues

Question 2 says we should find method used to assign probability

The method used is relative frequency method and it is determined by:

P(A) = frequency(f)/total number of data values(n).

Answer:

Set  B is not a subset of A.

Step-by-step explanation:

If there are sets, A and B with some elements, then B can be called subset of A, if every element of B is present in set A.

Example.

Example

A is set of integers

B is set of natural numbers

we know set of integers is all the negative numbers, 0 and all the positive discrete numbers like

A = {......-3,-2,-1,0,1,2,3,4........}

B is set of positive discrete numbers from 1 to infinity)

B =  {1,2,3,4........}

Thus, we see every element of B is present in A . Hence B is subset of A

___________________________________________

Given

A = {2, 3, 5, 7, 11}

B = {3, 5, 7, 9, 11)

Here,

In set B . elements 3,5,7,11 are present in set A, but

Element 9 from set B is missing Set A.

Since, every element of Set B is not present in set A hence

Set  B is not a subset of A.

Step-by-step explanation:

Point F bisects segment GH means that the segment GH is being divided into two by point F.

If GF = 14 1/2 feet

Since point F divides GH into two, multiplying GF by two will give segment GH

GH= 2GF

GH= 2(14 1/2

GH= 2(29/2)

Answer:

40 tablets

Step-by-step explanation:

What we want to do is find how many mg of antihistamine you can take in a week.

If you can take 19mg in 6 hours, that means you can take [tex]19\cdot4=76[/tex]mg per day (because [tex]24\div6=4[/tex], so you can take 19mg every 6 hours 4 times in a day.)

There are 7 days in a week, so you can take [tex]76\cdot7=532[/tex] mg per week.

Now, we know how many mg of antihistamine you can take per week. If we take antihistamine in increments of 13.2mg, then the total amount of tablets we can take per week is going to be [tex]532\div13.2[/tex], which is approximately equal to 40.

So you can take 40 tablets in a week if you are 100 pounds.

Answer:

x= 88

Step-by-step explanation:

1. 4 inside angles must sum to 360:

X = 360-45-65-95 = 155

2. All the outside angles must sum

To 360:

2x + 70+ 86 + 9 = 2x + 248

2x = 360-248

2x = 112

X = 112/2 = 56

3. Sum of interior angles for 6 sides figure = 720.

X = 720 - 90-120-130-140-150

X = 90

4. Exterior angles sum to 360

4x +x + 98 + 162 = 360

5x + 260 = 360

5x = 100

X = 100/5

X = 20

On 0.05 percentage of the spins did the spinner land on 2, according to the question.

For spins using the spinner geometry: Shape. Spinners are in the same category as dice. Spinners, in essence, give unpredictability to the creation of numbers, colors, or objects. It can be used in place of dice and vice versa to create numbers. IT may be used in a gaming scenario in the same manner that dice can be used to produce movements.

In 100 Spins it lands on 2 a total of 5 times

Therefore, it’s 5/100×100%

= 5%

So, the Answer is 5. So 5% .

To convert a percentage to a decimal, divide by 100. So 5% is 5/100, or 0.05. To convert a decimal to a percentage, multiply by 100 , move the decimal point 2 places to the right.
