HELP PLZ WHATS THE SURFACE AREA

Answer:

The slope of the line that is perpendicular is 3/8

Step-by-step explanation:

The slope of the line through

(-6,4) (10,-2)

m = ( y2-y1)/(x2-x1)

    = ( 10 - -6)/( -2 -4)

    = (10+6)/(-2-4)

     = 16/-6

    =-8/3

A line perpendicular has a slope that is the negative reciprocal

- 1/( -8/3)

+ 3/8

The slope of the line that is perpendicular is 3/8

Answer:

I would go with third one down     3 1/2

Step-by-step explanation:

2 1/3 × 1 1/2

7/3 × 3/2   =  (7×3)/(3×2)

                 = 21/6

                 = 3 3/6

                 = 3 1/2

Answer:

the answer is 62.8cm^2

Step-by-step explanation:

4•3.14•5

By using the formula for the surface area of the sphere [tex]S.A = 4 \pi r^2[/tex], the surface area of this sphere would be, [tex]S.A = 314[/tex] cm²

Used the formula of the surface area of the sphere,

[tex]S.A = 4 \pi r^2[/tex]

Where 'r' is the radius of the sphere.

Given that,

Diameter of a sphere = 10 cm

We know that the radius of the sphere is half of the diameter of the sphere.

Hence, the radius of the sphere is,

[tex]r = \dfrac{10}{2}[/tex]

[tex]r = 5[/tex] cm

Substitute r = 5 cm in the above formula,

[tex]S.A = 4 \pi r^2[/tex]

[tex]S.A = 4 \times 3.14 \times 5^2[/tex]

Therefore, the surface area of a sphere is,

[tex]S.A = 314[/tex] cm²

Answer:

1. college

2, salary

3. true experiment

4. 2

Step-by-step explanation:

1. in this scenario the independent variable is the college. that is  either walton college or non walton.

2. the dependent variable is the variable of interest. And this is salary. Students want to know what to major in that can give them a lot of salary when they start working.

3. This is a true experiment due to the random sample assigned.

4.  2 conditions to infer causation have been met.

Answer:

1. Yolanda's error is that the sample does not consist of all of Tichenor Middle School's students.

2. The sample size is 40 students. This is the sample size, because if you add up the amounts of students which voted for each animal, it adds up to 40.

Answer:

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

Step-by-step explanation:

I got 5/2 as my x variable and 3 for my y variable to being the midpoint. In which I added both my x variables provided ( 3 and 2 ) and then I divided them by two to get half of that (since you are looking for in between those two digits technically so you are wanting to find the midpoint or the middle of that line segment). I also did the same with the two y variables as well which were 7 and -1, then I divided both by two to get the variable 3.

Answer:

5/2, 3

Step-by-step explanation:

that should be your answer (hopefully)

Answer:

I'm pretty sure it's C.

Step-by-step explanation:

Answer: y = 12x + 5

Step-by-step explanation:

Since the going rate is $12/hr, that will be the x coefficient. Since the starting fee is $5, that will be the y-intercept.

Answer:

B. The sample selected from one of the populations has no effect or bearing on the sample selected from the other population.

Step-by-step explanation:

In statistical analysis, the use of independent samples for diverse studies is common.

Independent samples are such that the sample selected from one of the populations has no effect or bearing on the sample selected from the other population.

This means that samples are selected randomly in such a way that an observation obtained from a sample does not depend on the values obtained from the observation of another sample from the other population.

Answer:

[tex]57\frac{3}{11}[/tex] = c

or

[tex]57.\overline{27}[/tex] = c

Step-by-step explanation:

We know that the diameter of a circle multiplied by [tex]\pi[/tex] is the circumference, so we can create this equation:

180 = c * [tex]\pi[/tex]

Your teacher told us to assume [tex]\pi[/tex] is 22/7, so we'll put that in

180 = c * [tex]\frac{22}{7\\}[/tex]

To get c by itself, we divide both sides by 22/7

[tex]\frac{180}{\frac{22}{7}}[/tex] = c

Dividing by a number is the same as multiplying by its reciprocal, so we'll multiply 180 by 7/22

180 * [tex]\frac{7}{22}[/tex] = c

Evaluate

[tex]\frac{1260}{22}[/tex] = c

[tex]57\frac{3}{11}[/tex] = c

If you want a decimal instead:

[tex]57.\overline{27}[/tex] = c

Answer:

[tex]x = 5 \± \sqrt{31}[/tex]

Step-by-step explanation:

Given

[tex]6 = x^2 - 10x[/tex]

Required

The solution in radical form

[tex]6 = x^2 - 10x[/tex]

Rewrite as:

[tex]x^2 - 10x - 6 = 0[/tex]

Using the quadratic formula, we have:

[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]

Where

a = 1

b = -10

c = -6

So, we have:

[tex]x = \frac{-(-10) \± \sqrt{(-10)^2 - 4*1*(-6)}}{2*1}[/tex]

[tex]x = \frac{10 \± \sqrt{100 +24}}{2*1}[/tex]

[tex]x = \frac{10 \± \sqrt{124}}{2}[/tex]

Split the roots

[tex]x = \frac{10 \± \sqrt{4 * 31}}{2}[/tex]

Express [tex]\sqrt 4[/tex] as 2

[tex]x = \frac{10 \± 2\sqrt{31}}{2}[/tex]

Split the fraction

[tex]x = \frac{10}{2} \± \frac{2\sqrt{31}}{2}[/tex]

[tex]x = 5 \± \sqrt{31}[/tex]

The surface area for a pyramid that is: Base 8 and height 6

Would be: 42.87

Answer:

a)x₁  = 24  business owners plan to provide a gift this year

b)  p-value = 0,0017

c)p-value < α   we have to eject H₀   And support the claim that the proportion of business owners providing gifts has decrease

Step-by-step explanation:

a) Sample size 80

proportion  p₁  = 30 %   p₁ = 0,3

Then   x₁ = 80*0,3

x₁  = 24  business owners plan to provide a gift this year

b) Hypothesis Test

Null Hypothesis                    H₀          p₁  =  0,45

Alternative Hypothesis        Hₐ          p₁  <  0,45

p₁  =  0,3   then  q₁  =  1  -  0,3    q₁ =  0,7

z(s)  = ( p₁  -  0,45 )/ √p₁* q₁ / n

z(s)  =  -  0,15 / √0,002625

z(s) = - 0,15 / 0,05123

z(s) = - 2,9279

b)From z-table we find  p-value = 0,0017

c) If  α = 0,05   ( significance level )  as

p-value < α   we have to eject H₀   And support the claim that the proportion of business owners providing gifts has decrease
