x =

Answer:

a. At most 40

Step-by-step explanation:

If we take the survey that was done as a basis then we would use the 16% that was obtained as the number of overall US adults that have had their accounts used without their permission. Assuming that the 250 selected individuals were selected at random and without bias then those 250 would also be representative of the entire population. Therefore, we would simply need to multiply the number of selected individuals by the percentage in decimal form.

16 / 100 = 0.16

250 * 0.16 = 40

Finally, we can see that roughly 40 individuals would have had their email used without permission.

Answer:

The previous number keeps getting multiplied by - 2

Step-by-step explanation:

64 ×-2 = -128

-128 × -2 = 256

256 × -2 = -512

Answer:

-9

Step-by-step explanation: I know this problem since I use khan academy too and I got the answer wrong and it helped by saying it was -9.

Answer:

94 boxes of samoas

131 boxes of thin mints

Step-by-step explanation:

m=mints

s=samoas

s+m=225    m=225-s

s(2.5)+m(3)=628

2.5s+3m=628

substitute for m

2.5s+3(225-s)=628

2.5s+675-3s=628

reduce

-0.5s=-47

s=94

m=131

Problem 1

Two things you could measure is a person's height and the speed needed to reach the planet Mars. The person's height can be measured with a low level of precision, which means we don't need to be that accurate. We could say "that person is about 6 feet tall" and whoever is listening would get a sense of their height. In contrast, we need high precision for a rocket speed to Mars because getting this figure wrong would likely cause disaster down the road. Very complicated mathematics is essential to make sure we hit the target required in space.

===============================================

Problem 2

As mentioned, we need high precision when it comes to anything dealing with space travel. If the calculations are wrong, then the spacecraft could crash somehow. As one example where things went wrong, engineers used the wrong values and the Mars lander ended up crashing into the planet rather than landing safely. The high cost of such space exploration missions means that it's very crucial to get precise values as much as possible, to as accurate as possible. Things like discussing a person's height isn't that essential to be very precise as we can just relay estimates to whoever we're talking to. This informal setting doesn't demand as much accuracy compared to something like a rocket launch.

Answer:

point-slope:x-y+3

slope-intercept: y=x-3

Answer:

Answer:

x is less than or equal to negative 14.

Step-by-step explanation:

so for now we should pretend that the greater than or equal to is an equal sign, and simplify the problem to get x alone on a side

remove 5 from each side

-x/3=1/3-5

-x/3=14/3

multiply both sides by 3

-x=14

x=-14

so we can now replace the equal sign with the equal or greater to, so x is less than or equal to -14

sum of all exterior angles equals to 360

sum of interior angles equal to 180

divide 360 by 122 to find b the rest you'll get it

Answer:

The area of the base of a box is 1800 cm².

Step-by-step explanation:

We have:

H: is the height = 4 cm

[tex]A_{l}[/tex]: is the lateral surface area = 120 cm

L = 2B                                                                

We can find the breadth of the base by using the lateral surface area and the height:

[tex] A_{l} = H*B [/tex]        

[tex] B = \frac{A}{H} = \frac{120 cm}{4 cm} = 30 cm [/tex]

Now, if the length is twice its breadth we have:

[tex] L = 2B = 2*30 cm = 60 cm [/tex]

Hence, the area of the base is:

[tex] A_{b} = B*L = 60 cm*30 cm = 1800 cm^{2} [/tex]

Therefore, the area of the base of a box is 1800 cm².

I hope it helps you!

Answer:

This function is a continuous linear function that's domain is all positive real numbers.

Step-by-step explanation:

This function is continuous because every linear function is continuous and this function is the linear function y = 2x+14 where x is the years it has been planted and y is the height.

It is a linear function, it's hard to explain, but it has a dependent variable, the height of the tree that changes at a constant rate with the independent variable which is time in years.

The domain is all positive real numbers since time/years can not be negative.

Answer:

29

Step-by-step explanation:

We can use the pythagorean theorem to find the length of the ladder

[tex] {20}^{2} + {21}^{2} = c {}^{2} [/tex]

[tex]400 + 441 = {c}^{2} [/tex]

[tex]841 = {c}^{2} [/tex]

[tex]c = 29[/tex]

The answer is 29

Answer:

P(Green ball) = 1/3

Step-by-step explanation:

You have a sack of 90 balls. 35 blue, 30 green and 25 pink. If you randomly pull one ball out of the bag, what is the probability of pulling a green ball?

The Probability of pulling a green ball =

P(Green ball) =

Number of green balls/ Total number of balls

= 30 green balls/90 balls

P(Green ball) = 1/3

Answer:

b - 0.60b

= 0.40b

Step-by-step explanation:

The expression would be

here the original cost is b

And Juan sells it for 60% less than original price

So the expression is

= b - 0.60b

= 0.40b

This would be the expression that shows the selling price of the boat

Answer: Choice B

They did not perform the cross multiplication properly

The correct step should be m*24 = 8*15 which solves to m = 5

========================================================

Explanation:

In general, if we had the equation A/B = C/D, then it cross multiplies to A*D = B*C. We refer to this as cross multiplication because of the shape made when we connect the terms (to figure out what multiplies with what). The diagram below shows what I mean.

So that's why m/8 = 15/24 cross multiplies to m*24 = 8*15

Simplifying things a bit leads to 24m = 120. Then we divide both sides by 24 to fully isolate m and we get m = 120/24 = 5. Therefore, m = 5.

Answer:

x = 29.4

y = 17

Step-by-step explanation:

sin 90° / 34 = sin 60° / x

x = 34·sin 60°

x = 29.4

sin 90° / 34 = sin 30° / y

y = 34·sin 30°

y = 17

Answer:

x = -2 is a function

Step-by-step explanation:

To get which is a zero, we have to look at one value of x which when substituted into the polynomial will give -1

we have this as:

Let us try the value x = -2

-2^5 + 2(-2)^4 - 2 + 2

= -32 + 32 - 2 + 2 = 0

This means that the term x = -2 is a root of the equation
