How do we maintain the value of the equivalent fractions we create? Hint: I am referring to the numerator and denominator

<span>A fraction is normally expressed in its lowest form. It means that there is no common factor for the numerator and denominator. A common factor is a number that can divide both the numerator and the denominator without a remainder. A fraction in its lowest form can have any number of equivalent fractions. To create equivalent fractions, multiply both the denominator and the denominator by the same number. For example, 1/2 will become 2/4 when multiplied by 2 and 3/6 when multiplied by 3. We can use any number to multiply but we must multiply both the numerator and the denominator.</span>

Helena uses a mixture of compost and topsoil in her garden. She purchased a total of 10 cubic yards of compost and topsoil for $
Annette [7]

Let C be the amount of compost

T be the amount of  topsoil

Each compost cost = $25

Cost of C compost = 25C

Each topsoil cost = $15

Cost of T topsoil = 15T

Amount of compost + amount of topsoil = 10

C + T = 10 -------> Equation 1

cost of C compost + cost of T topsoil = 180

25C + 15T = 180 --------> equation 2

Solve  the first equation for C

C + T = 10

C = 10 - T

Now plug it in second equation

25C + 15T = 180

25 ( 10 - T) +15T = 180

250 - 25T + 15T = 180 (combine like terms)

250 - 10 T = 180 (Subtract 250 on both sides)

-10T = 180 - 250

-10T = -70 ( divide by -10 on both sides)

T = 7

She purchased  7 cubic yards of topsoil .

I need help, can someone help me
Zarrin [17]

Answer:

Yes, the price is proportionate. Every rose cost 3 dollars.

Step-by-step explanation:

1 rose * 3 dollars = 3

3 rose * 3 dollars = 9

6 rose * 3 dollars = 18

9 rose * 3 dollars = 27

12 rose * 3 dollars = 36

15 rose * 3 dollars = 45

Equation

R*3=P

OR

Number of roses* 3 dollars per rose = Prices (Dollars)

When referring to the normal probability distribution, there is not just one; there is a "family" of normal probability distribu
pishuonlain [190]
<span>A probability distribution is formed from all possible outcomes of a random process (for a random variable X) and the probability associated with each outcome. Probability distributions may either be discrete (distinct/separate outcomes, such as number of children) or continuous (a continuum of outcomes, such as height). A probability density function is defined such that the likelihood of a value of X between a and b equals the integral (area under the curve) between a and b. This probability is always positive. Further, we know that the area under the curve from negative infinity to positive infinity is one. The normal probability distribution, one of the fundamental continuous distributions of statistics, is actually a family of distributions (an infinite number of distributions with differing means (ÎĽ) and standard deviations (Ď). Because the normal distribution is a continuous distribution, we can not calculate exact probability for an outcome, but instead we calculate a probability for a range of outcomes (for example the probability that a random variable X is greater than 10). The normal distribution is symmetric and centered on the mean (same as the median and mode). While the x-axis ranges from negative infinity to positive infinity, nearly all of the X values fall within +/- three standard deviations of the mean (99.7% of values), while ~68% are within +/-1 standard deviation and ~95% are within +/- two standard deviations. This is often called the three sigma rule or the 68-95-99.7 rule. The normal density function is shown below (this formula won’t be on the diagnostic!)</span>
