cones and pyramids both have only one base ?

Answer:

The axis of symmetry is  -b/2a

The x-intercept shown is 3 units away from the axis of symmetry.

The other x-intercept also must be 3 units away from the axis of symmetry but on the opposite side.

Subtract 3 from the axis of symmetry.

The other x-intercept is  (-b/2a-3,0)

Answer:

Dependent Variable = tips left by male customers

Independent Variable = T-Shirt color worn by waitresses

Step-by-step explanation:

Dependent variable is the variable that changes when the independent variable changes.

In other words, when the independent variable is varied, the dependent variable changes. The dependent variable is the effect or outcome of the manipulation of the independent variable.

In the study referred to in the question above, the amount of tips given to waitresses is dependent on the color of the T-shirt the waitresses wear.

Therefore, the dependent variable is T-Shirt color, while the independent variable is the amount of tips given.

Answer:

ΔT =313.5 K - 240.3 K = 73.2 K

Step-by-step explanation:

It's more confortable to work in °C to determine the Absolute value

T°C + 273 = T° K (Kelvin grades)

ΔT = Highest T° in K - Lowest T° in K

We make the conversion to Celsius degree, from Farenheit:

(x F - 32°) . 5/9 = °C

(105 F - 32°) . 5/9 = 40.5°C

(-27 F - 32°) . 5/9 =  - 32.7 °C

40.5°C + 273 = 313.5 K

-32.7 °C + 273 = 240.3 K

Answer:

x=3

Step-by-step explanation:

the volume of the prism with triangular base is 54 unit³

The base is a triangle with,  base i.e 4 units  and  height i.e x units

Also,  height of the prism = 3x

So, volume of the prism is,

And

,

[tex]Area_{Triangle}=\dfrac{1}{2}\times base\times Height_{Triangle}=\dfrac{1}{2}\times 4\times x=2x\ unit^2[/tex]

Then,

[tex]V_{Prism}=2x\times 3x=6x^2[/tex]

As the volume is given as 54 unit³, hence

6x²=54

x²=9

Answer:

y = 42 - 3/4 * x

Step-by-step explanation:

From the statement we know that the following:

x + y = 56

y = 56 - x

x beads of Nicole and another person's beads, after losing a 1/4 of the beads, it would be:

y = (3/4) * (56 - x)

y = 42 - 3/4 * x

From here on you should know the number of beads that Nicole has or suppose, for example:

x = 12

y = 42 - 3/4 * 12

y = 33

Therefore, you would have 33 beads.

Answer:

x = 9 y = -4

Step-by-step explanation:

4x + 3y = 24 . (-5) ------> -20x -15y = -120 (A)

6x + 5y = 34 . (3) -------> 18x + 15y = 102 (B)

(A) + (B) ----------> -2x = -18 ---------> x = 9

4.9 + 3y = 24

3y = 24 - 36

3y = -12

y = -4

Answer:

40 minutes

Step-by-step explanation:

Let's take the average playing time as u, and let the standard deviation be [tex] \sigma [/tex].

Thus,

[tex] u = 34 [/tex]

[tex] \sigma = 6 [/tex]

To find the value of 1 standard deviation above the mean, we have:

[tex] u + 1\sigma [/tex]

Since u = 34 minutes and [tex]1\sigma [/tex] = 6 minutes, we now have:

[tex] = 34 + 6 = 40 [/tex]

The value (in minutes) of 1 standard deviation above the mean is 40 minutes.

Answer:

40 minutes

Step-by-step explanation:

Given that:

The average time playing time of compact disc in a large collection= 34 minutes and the standard deviation = 6 minutes.

Let [tex]\mu[/tex] represent the average playing time and [tex]\sigma[/tex] to be the standard deviation.

So;

[tex]\mu = 34 \\ \\ \sigma = 6[/tex]

The value for 1 standard deviation above the mean is;

[tex]x+1 s= 34+6 \\ \\ = 40[/tex]

Answer:

60y

where y is the number of houses each volunteer can build

Step-by-step explanation:

I'll assume this is a complete question and i'll try to solve it the best way i can mathematically.

Let us assume that one volunteer can build a certain number of houses, say y houses.

Also, it is stated that the amount of houses that can be built varies directly as the with the number of volunteers. Therefore, it will be mathematically logical to say that if 1 volunteer can build y number of houses, then 60 volunteers will build 60y houses

Answer:

The standard error of the proportion is 0.0367.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the standard error is [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

In this question:

[tex]p = 0.16, n = 100[/tex]

So

[tex]s = \sqrt{\frac{0.16*0.84}{100}} = 0.0367[/tex]

The standard error of the proportion is 0.0367.

Answer:

5 km.

Step-by-step explanation:

We have to calculate the distance if we apply the speed formula that would be the distance in a given time:

v = d / t

therefore, if we solve for distance it would be:

d = v * t

Now the speed is 6 km / h but the time must be calculated, it leaves at 9:15 and returns at 10:05, that is, there is no exact time but 50 minutes, one hour equals 60 minutes, therefore:

50 min * 1 h / 60 min = 0.833 h, that is, the child took 0.833 hours to get to school, now if we replace:

d = 6 * 0.8333

d = 5

In other words, the distance between the school and the house is 5 km.

Answer:

p=-3

Step-by-step explanation:

5-3x = Px +7

-7 from both sides

-2-3x=Px+7

add 3x to both sides

-2=Px+3x

P =-3 because it will get rid of variable

Answer:

x= -22.5

Step-by-step explanation:

5–3x=Px + R

r= 7

P= 42

5–3x =42x + 7

-3x -42x = 7- 5

-45x =2

x= -22.5

Answer:

D = 24 units

Step-by-step explanation:

Using Distance Formula

Distance Formula = [tex]\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]

D = [tex]\sqrt{(1-25)^2+(-3+3)^2}[/tex]

D = [tex]\sqrt{(-24)^2+(0)^2}[/tex]

D = [tex]\sqrt{576}[/tex]

D = 24 units

Answer:

18

Step-by-step explanation:

Do 72 divided by 4 because it is a square so all sides are equal

Hiya! ✌.ʕʘ‿ʘʔ.✌

Okay, so with a square, ALL sides are EQUAL.

To find the perimeter of a shape, you just need to add the measure of all sides together.

What you can do, is since all sides are equal, and a square has four sides, just get the measure of ONE side and multiply that by 4! (ﾉ◕ヮ◕)ﾉ*:･ﾟ✧

The perimeter is 72 meters and if we find the value of u, we get the value of all sides.

Let's set this up as an equation:

P = 4u where P = perimeter and u = measure of one side

Let's insert the given value (72) into the equation for perimeter

72 = 4u

Now we have to solve for u, and to do that, we have to get it by itself on that side of the equation. u is being multiplied by 4, so do the opposite by dividing both sides of the equation by 4!

72/4=18

4u/4=u

Now our equation looks like this:

18 = u

So the value of u is 18! (✿◠‿◠)

To prove it, insert it into the formula... P = 4(18)... P = 72.

Boom! :D

Answer:

  x^2 +16 is prime

Step-by-step explanation:

A prime polynomial is one that cannot be factored using integers.

Answer:

a.

Network             CBS   NBC   FOX   ABC

f                           9          9         1           6

Relative f          0.36     0.36    0.04     0.24

Percent f            36          36       4          24

b.

CBS and NBC have done best in presenting top-rated television shows.

The most top rated shows are from CBS and NBC while ABC network also has top rated shows but CBS and NBC percentages are higher.

Step-by-step explanation:

a.

Network        f Relative f  Percent f

CBS          9         0.36 36

NBC       9         0.36 36

FOX        1         0.04 4

ABC       6         0.24 24

"f" represents the frequency of network.

"Relative  f" represents relative frequency of Network.

"Percent f" represents percent frequency of Network.

Frequency is computed by counting the number of times value repeated in the data. So, the frequency distribution is

Network  Frequency

CBS         9

NBC         9

FOX         1

ABC         6

Relative frequency is computed by dividing the frequency to the sum of frequencies.

sum of frequencies=9+9+1+6=25.

So, the relative frequency distribution is

Network  Relative frequency

CBS          9/25=0.36

NBC         9/25=0.36

FOX         1/25=0.04

ABC         6/25=0.24

Percent frequency is computed by multiplying relative frequencies to 100.

So, the Percent frequency distribution is

Network    Percent frequency

CBS             0.36*100=36

NBC             0.36*100=36

FOX             0.04*100=4

ABC             0.24*100=24

b.

From frequencies, relative frequencies and percent frequencies we can see the CBS and NBC have equally higher cont of top rated shows comparative to ABC and  FOX. ABC has second highest top rated shows while Fox has least top rated shows among other networks.
