Answer:

The price of fertilizer is $27.5  and potting soil is $5

Step-by-step explanation:

I think that you are asking for the price of each bag of fertilizer and potting soil. And here is my answer:

Given the system of linear:

3s + 4f = 125  <=> f = 31.25 -3/4s (1)

4s + 2f = 75   <=> f = 37.5 -2s (2)

Take (1) -(2) we have:

f -f = 31.25 -3/4s - (37.5 -2s)

<=> 0 = -6.25 + 1.25s

<=> 1.25s  = 6.25

<=> s = 5

=> f = 37.5 -2(5) = 27.5

So the price of fertilizer is $27.5  and potting soil is $5

What is 90.69 rounded to the nearest tenth
kolezko [41]
90.69 rounded to the nearest tenth.
Go to the tenth value of the number and look to the number right of that. If it is 5 or higher, you round up; 4 or less, round down
9 is higher than 5 therefore you round up
90.69 becomes 90.7

Romashka-Z-Leto [24]

Answer:

a

\= x  =  82

b

s =  9.64

Step-by-step explanation:

From the question we are told that

    The data is  87  91  86  82  72  91   60  77  80  79  83  96

Generally the point estimate for the mean is mathematically represented as

    \= x  =  \frac{\sum  x_i }{n}

=>  \= x  =  \frac{87 +91 + 86 + \cdots  + 96}{12}

=>    \= x  =  82

Generally the point estimate for the standard deviation  is mathematically represented as

      s =  \sqrt{\frac{ \sum ( x_i  - \= x )^2 }{ n -1 } }

=>     s =  \sqrt{\frac{ ( 87 - 82  )^2 +( 91 - 82  )^2 + \cdots + ( 96 - 82  )^2  }{ 12 -1 } }

=>     s =  9.64

4/16 in the lowest terms
miskamm [114]

Answer:

1/4

Step-by-step explanation:

The answer is 1/4 because 4 is the greatest common factor (GCF) of both numbers. So you divide both numbers by 4.

4 ÷ 4 = 1

16 ÷ 4 = 4

Therefore, the answer is 1/4.
