43/50

31/50=0,62

17/25=0,68(0,06 more)

37/50=0,74(0,06 more)

4/5=0,8(0,06 more)

43/50=0,86(0,06 more)

Next decimal should be 0,86

You need to find a fraction from the decimal 0,86

0,86=86/100=43/50

write an equation to solve and find the answer to the following rate problem. a garden store sells six plants per hour how many

Virty [35]

Let x represent the number of plants that they will sell in five hours

We were told that the garden store sells six plants per hour. This means that

6 plants = 1 hour

then,

x plants = 5 hours

By cross multiplying, it becomes

x * 1 = 6 * 5

x = 30

They will sell 30 plants in 5 hoursx

The function f(x) = 200(0.5)x/50 models the amount in pounds of a particular

victus00 [196]

Answer:

29 years

Step-by-step explanation:

Given the function $f(x)= 200(0.5)^{\frac{x}{50} }$ , where x stands for the number of years since the material was put into the vault, we can plug 140 into x to find the amount leftover.
Another way of doing this is to change the function to $f(x)=200(0.5^{\frac{1}{50} })^{x}$ which are equivalent functions, and then plug 140 into x. This function is helpful if you also needed to find the rate.
I'll use the 1st function because the question doesn't ask for the rate

$f(x)= 200(0.5)^\frac{140}{50}}$

From here I'll just use a calculator & get 28.7, or 29 years.

The on-line access computer service industry is growing at an extraordinary rate. Current estimates suggest that only 20% of the

vitfil [10]

Answer:

The probability is 0.4207

Step-by-step explanation:

The probability of a home-based computer having access to on-line services is p = 0.2 (data from the exercise)

Then, the probability of a home-based computer not having access to on-line services is p = 1 - 0.2 = 0.8

We are going to use this probability (p = 0.8) to solve the exercise.

Let's define the random variable X

X : ''Number of home-based computers not having access to on-line services''

X can be modeled as a binomial random variable

X ~ Bi(p,n)

X ~Bi(0.8,25)

Where p is the success probability and n is the number of Bernoulli independent experiments we are taking place.

We are going to count ''a success'' as a computer not having access to on-line services.

The binomial probability function is :

$P(X=x)=(nCx)p^{x}(1-p)^{n-x}$

Where P(X=x) is the probability of the random variable X to assume the value x

nCx is the combinatorial number define as

$nCx=\frac{n!}{x!(n-x)!}$

p is the success probability and n the number of Bernoulli independent experiments taking place.

In our exercise,

$p=0.8\\n=25$

We are looking for :

$P(X>20)=P(X=21)+P(X=22)+P(X=23)+P(X=24)+P(X=25)$

$P(X>20)=(25C21)0.8^{21}0.2^{4}+(25C22)0.8^{22}0.2^{3}+(25C23)0.8^{23}0.2^{2}+(25C24)0.8^{24}0.2^{1}+(25C25)0.8^{25}0.2^{0}$

$P(X>20)=0.1867+0.1358+0.0708+0.0236+0.8^{25}$

$P(X>20)=0.4207$

Finally, the probability of finding that more than 20 of 25 home-based computers do not have access to on-line services is 0.4207

Please help me with this ACT Prep problem.

Answer:

Option C

Step-by-step explanation:

ΔABC and ΔDEF are similar triangles.

By the property of similar triangles, corresponding sides of the similar triangle are proportional.

$\frac{AB}{DE}=\frac{BC}{EF}=\frac{AC}{DF}$

$\frac{6}{DE}=\frac{6}{3}=\frac{10}{5}$

$\frac{6}{DE}=\frac{6}{3}$

DE = 3

Perimeter of ΔDEF = Sum of measures of the sides of the triangle

= DE + EF + DF

= 3 + 3 + 5

= 11

Therefore, Option C will be the correct option.
