Graph A, and graph C could not possibly be density curves for a continuous random variable if they were provided with the right scale.

Given four graphs of different nature as options.

We are required to find a graph that is not a continuous variable.

In mathematics, a continuous function is a function such that a continuous variation of the argument induces a continuous variation of the value of the function.

Continuous lines are those lines that when decreased, decrease with continuity and when increased, increase with continuity.

When we observe graph A, graph C. In these graphs, the value of the function keeps increasing and decreasing a lot and is not in continuity.

Hence, graph A, and graph C could not possibly be density curves for a continuous random variable if they were provided with the right scale.

[tex]\frac{2}{4}[/tex] is really 0.5

[tex]\frac{8}{20}[/tex] is really 0.4

So, it is not equal. If you need me to explain more. I will. :)

Answer:

False. [tex]\frac{8}{20} = \frac{2}{5}[/tex]

Step-by-step explanation:

When you divided [tex]\frac{8}{20}[/tex] by GCF your answer comes out as [tex]\frac{2}{5}[/tex].

I.e.) The GCF is (4)

[tex]\frac{8}{20}[/tex] ÷ [tex]\frac{4}{4}[/tex]=[tex]\frac{2}{5}[/tex]

Answer:

he is right

Step-by-step explanation:

Answer:

He weighs 172 pounds

Step-by-step explanation:

you can look up conversions like this on google and it will give you the exact weight and everything!

After converting Lucas's weight of 78 kg is 171.192 pounds

It is the conversion of one unit to another unit with its standard conversion.

Example:

1 hour = 60 minutes

1 km = 1000 m

We have,

78 kg

Now,

1 kg = 2.204 pounds

Multiply 78 on both sides.

78 kg = 78 x 2.204 pounds

78 kg = 171.912 pounds

Thus,

78 kg is 171.912 pounds

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Im not exactly sure about this, but i think for the first step, you would do 120*35/100=42 (35/100 is 35%). Then you take 120 and subtract 42, cuz thats how much you took off. 120-42=78. Then, you do 78/120*100 to get the percent you have left. 78/120*100=65%. The simpler way to do it, seeing as there arent mutiple sales on this pair of shoes, is just subtract 35 from 100 to get 65%

Answer:

c: 65% of the answer

Step-by-step explanation:

$120 is 100% we need to find the discount which is 100%-35% = 65%

You will pay now $78 for the shoes.

cross-check 120/100*65 = $78

[tex]15516.3163[/tex]

Step-by-step explanation:

[tex]8500\cdot(1.034)^{18}=15516.3163[/tex]

If Levi invested $8,500 in an account paying an interest rate of 3.4% compounded continuously. Assuming no deposits or withdrawals are made, how much money, to the nearest ten dollars, would be in the account after 18 years will be $15,516

Using this formula

Amount=P(1+r)n

Where:

p represent principal=$8,500

r represent rate=3.4% or 0.034

n represent number of years=18 years

Let plug in the formula

Amount=$8,500(1+0.034)∧18

Amount=$8,500(1.034)∧18

Amount=$8,500(1.82544)

Amount=$15,516

Inconclusion if Levi invested $8,500 in an account paying an interest rate of 3.4% compounded continuously. Assuming no deposits or withdrawals are made, how much money, to the nearest ten dollars, would be in the account after 18 years will be $15,516

Answer:

-48 ÷ 12

Step-by-step explanation:

account balance changed over a year = -$48

In a year, there are 12 months. Above statement can also be written as

account balance changed in 12 months = -$48

we have to find monthly change, so we divide LHS and RHS by 12

account balance changed in 12 /12 months = -$48/12

Thus, account balance changed in 1 months = -$48/12

which is represented  option 4 i.e -48 ÷ 12

Answer:

d) the slope of f(x) is greater than the slope of g(x)

Step-by-step explanation:

to find the slope of an equation, you look at its rise/run. for f(x), you can see that from one point (0, 3) to another (1, 1) it goes down 2 values (3 - 1) and over 1 value (0 + 1). because it goes down 2 values, the rise is -2, and because it moves to the side 1 value positively, the run is +1.

-2/+1 = -2. this means the slope of f(x) = -2.

finally, it says the slope of g(x) = -6, and -2 > -6. i hope this helps! :)

Answer:

Candy=x=2.8 bags

Cookies=3+2.8=5.8 bags

Step-by-step explanation:

Price

Bag of candy=$6.00

Bag of cookies=$4

Total sales=$40

Quantity

Let cookies=y=3+x

Let candy=x

There are 3 more bag of cookies than candy sold

Total sales=price*quantity of x + price*quantity of y

40=$4*(3+x) + 6*x

40=12+4x+6x

40=12+10x

40-12=10x

28=10x

X=28/10

x=2.8 bags

Answer:

1.50c +18

Step-by-step explanation:

The constant price is 18 dollars, which never changes and for every topping you get, it costs $ 1.50. Since we don't know how many extra toppings are added we write 1.50c.  This shows that the price will be determined by the number of extra toppings added. If you got no toppings, sub in 0 for c to get $ 18 .

Answer:

1.50c+18

Step-by-step explanation:

The base price of the large cheese pizza is $18.  Since we don't know how many extra toppings are added we write 1.50c.  This shows that the price will be determined by the number of extra toppings added.  Since the question asked for an expression and not an equation, there is no equals sign.
