I need help please ????!!!!

Answer:

for A

volume of cuboid =10×8×3=240cm³

volume of cylinder =πr²h=π×4²×7=351.85cm³

so volume of cylinder is greater

for B

surface area of cuboid =2(LB+BH+LH)=2(10×8+8×3+10×3)=268cm²

surface area of cylinder =2πr(r+h)=2×π×4(4+7)=276.36cm²

so surface area of cylinder is greater surface area than of cuboid

Answer:

F and B (as far as I can see).

Step-by-step explanation:

First, let's simplify the equation. You can easily do this by dividing by -4.

                                                  -4x < 20

                                                   /-4    /-4

                                                      x > -5

REMEMBER- Whenever dividing or multiplying a negative number with inequalities, the sign flips!!

On A, we can see that it has a negative symbol, but if we were to divide that, the sign would flip, making -5 greater than x. That's not what we want.

On B, the 20 is negative instead of the 4. Does this change anything?

                                                   4x > -20

                                                   /4    /4

                                                      x > -5

Nope! It still simplifies to what we had at the beginning so it works!

C and D are slightly confusing me because, well, I don't really see how it's relevant to anything so... It doesn't even have a inequality symbol so I don't know lol.

E is wrong because we need the 5 to be positive.

F is obviously right compared to our first answer.

Answer:

Move the decimal two places to the right and add a percent sign.

Step-by-step explanation:

.15= 15%

1.25= 125%

.06= 6.0, or 6%

Answer:

To convert a percent to a decimal, we move the decimal point 2 places to the left, just as we did when we were dividing by 100.

[tex]\frac{1}{5}[/tex]

Step-by-step explanation:

Consider the curve [tex]y=3x^2-5x[/tex]

Differentiate with respect to [tex]x[/tex]

[tex]\frac{dy}{dx} =3(2x)-5=6x-5[/tex]

( Use [tex]\frac{d}{dx}(x^n)=nx^{n-1}[/tex] )

Slope of normal curve is given by [tex]\frac{-1}{\frac{dy}{dx} }[/tex]

Slope of normal curve = [tex]\frac{-1}{6x-5}[/tex]

To find slope of normal curve at point [tex](0,0)[/tex] ,put [tex]x=0[/tex] in [tex]\frac{-1}{6x-5}[/tex]

Slope of normal curve at point [tex](0,0)[/tex] = [tex]\frac{-1}{6(0)-5} =\frac{-1}{-5}=\frac{1}{5}[/tex]

Answer:

x = 13, and y = 32.5

Step-by-step explanation:

A parallelogram's angles will all have to add up to 360 degrees.

We can count 55° and 60° twice, because of the interior angle rule.

So:

2 (55 + 60)

360 - 230 = 130

So:

5x = 2y = 65

130 ÷ 2 = 65

5x = 65

x = 65 / 5

x = 13

2y = 65

y = 65 / 2

y = 32.5

Step-by-step explanation:

for bob;

his grades = 2, 2, 2, 2, 2, 10, 10, 10, 10, 10.

total = 60

mean = total/n

= 60/10 = 6

meadian is the middle value in the set of scores. the numbers are even so =

2+10 / 2

median = 12/2 = 6

standard deviation using excel = 4.216

for tom

7, 7, 7, 7, 7, 7, 7, 7, 7, 7

total = 70

mean = 70/10 = 7

median = 7+7/2 = 14/2 = 7

standard deviation using excel = 0

for pat:

1, 1, 8, 8, 8, 8, 8, 8, 10, 10

total = 70

mean = 70/10 = 7

Answer:

1. 1/80 = 0.0125

2. 1/2 = 0.5

3. 280

4. 23.09

5. 1/2 = 0.5

Step-by-step explanation:

1. height of probability density function

[tex]\frac{1}{320-240} \\= \frac{1}{80}[/tex]

= 0.0125

2. probabilty that you will win the auction given a bid of 280

= [tex]\frac{280-240}{320-240} \\=\frac{40}{80} \\= \frac{1}{2}[/tex]

3. mean secret service price

[tex]\frac{320+240}{2} \\=\frac{560}{2} \\= 280[/tex]

4. the standard deviation of the above

= (320-240)/12^1/2

= 23.09

5. with a new bid of 300 dollars, probability you will win auction

= [(300-280)/(320-240)]/[(320-280)/(320-240)

= (20/80) / (40 /80)

= 0.25/0.5

= 0.5

Answer:

Price after sale = $52.5

Amount saved = $22.5

Step-by-step explanation:

Cost of Jacket - $75

Percentage off = 30%

Discount price = 30% of $75

Discount price = 0.3 * 75

Discount price = $22.5

Price after sale = Original cost - Discount price

Price after sale = 75-22.5

Price after sale = $52.5

The amount saved = 75 - 52.5

The amount saved = $22.5

Answer:

It represents growth, and the percentage rate of increase is of 8%

Step-by-step explanation:

Exponential equation:

An exponential equation has the following format:

[tex]A(t) = A(0)(1 + r)^t[/tex]

In which A(0) is the initial amount and r is the rate of change, as a decimal. If positive, it is growth, if negative, it is decay.

In this question:

[tex]y = 21(1.08)^x[/tex]

So

[tex]1 + r = 1.08[/tex]

[tex]r = 0.08[/tex]

Since r is positive, it represents growth, and the percentage rate of increase is of 0.08*100% = 8%

[tex] \frac{5}{3} [/tex]

~ See attatchment

Step-by-step explanation:

I'm unsure what you want me to do here, so I drew a graph (using Desmos) and the slope.

The slope is given, 5/3. The slope-intercept equation is usually y = mx + b -- m being the slope and b being the y-intercept.

Hi!

Let's check if the equation that we're going to work with is in slope-intercept form.

Remember, the slope-intercept formula is:

                                   [tex]\diamondsuit~~~\boldsymbol{y=mx+b}[/tex]

Where:

Details:

[tex]\boxed{\\\begin{minipage} {8cm}\sf{Slope = coefficient \ of \ x, \ or \ the \ number \ before \ x.}\\\sf{Y-intercept = \ a \ number \ added \ to \ or \ subtracted \ from \ the \ slope.} \end{minipage}}[/tex]

Therefore:

[tex]\stackrel{\heartsuit}{\boxed{\boxed{\textsc{Slope:}\quad\boldsymbol{\displaystyle\frac{5}{3}}}}}[/tex]

Answer:

the mean is 4.86 & the mad is 1.91 hope this helped you and pls give me the Brainly crown

Step-by-step explanation:

The sine function is:

f(x) = -2*sin(x/2) + 3.

So you got it almost correctly, you only forgot to apply the reflection.

We start with the general sine function:

[tex]a*g(w*x + p) +m[/tex]

where g(x) = sin(x)

f(0) = 2*sin(w*0 + p) + 3 = 3

      = 2*sin(p) + 3 = 3

Then we must have p = 0, so there is no phase shift.

We also know that we have a reflection over the x-axis of the parent sine function, we would actually have:

f(x) = 2*-sin(wx) + 3

Finally, to get the value of k we know that the period of the general sine function is 2*pi, while here is 4*pi, then we must have w = 1/2 to get the correspondent correction, so the function is:

f(x) = -2*sin(x/2) + 3.

This is almost the same thing that you got in the graph, where you only forgot to apply the reflection over the x-axis of the parent function.

The area of a triangle is 1/2 x base x height.

When you know the base and the height of a triangle, multiply them together, than multiply by 1/2 ( this is the same as dividing it by 2).

Answer:

Base times height divided by 2 = area.
