Answer:

Stephanie requires 835.75 square feet more amount of soil to cover her yard.

Step-by-step explanation:

Given:

Total square feet of yard she need to cover with soil = \frac{4103}{4}\ ft^2

\frac{4103}{4}\ ft^2 can be rewritten as 1025.75 square feet.

Total square feet of yard she need to cover with soil = 1025.75\ ft^2

Amount of soil in one bag = 125\ ft^2

Amount of soil in other bag = 65\ ft^2

Total Amount of soil she has is equal to sum of Amount of soil in one bag and Amount of soil in other bag.

Framing the equation we get;

Total Amount of soil she has= 125+65 = 190\ ft^2

Now We need to find the Amount of soil she required more to cover the yard.

Amount of soil she required more is equal to difference of Total Amount of soil she has and Total square feet of yard she need to cover with soil.

Framing the equation we get;

Amount of soil she required more = 1025.75-190= 835.75\ ft^2

Hence Stephanie requires 835.75 square feet more amount of soil to cover her yard.

Inessa [10]

The probability according to the given scenario is:

(a) <em>0.0395</em>

(b) <em>0.95</em>

(c) <em>0.076</em>

The given values are:

  • P(B/A) = 0.79
  • P(A) = 0.05

(a)

The probability that the  b/w has tuberculosis as well as having (+) test will be:

→ P(A \cap B) = P(B/A).P(A)

By substituting the values, we get

→                  = 0.79\times 0.05

→                  = 0.0395

(b)

The probability that a person does not have tuberculosis will be:

→ P(A') = 1-P(A)

→            =1-0.05

→            = 0.95

(c)

The person does not have tuberculosis as well as have a (+) test, the probability will be:

→ P(A' \cap B) = P(A').P(B/A')

→                  = 0.95\times 0.08

→                  = 0.076

Answer:

  3, 8, 14, 30, 58

Step-by-step explanation:

As with all formulas, put the numbers in place of the corresponding variables, and do the arithmetic.

  a_1=3\qquad\text{given}\\\\a_2=8\qquad\text{given}\\\\a_3=2a_1+a_2=2(3)+8=14\\\\a_4=2a_2+a_3=2(8)+14=30\\\\a_5=2a_3+a_4=2(14)+30=58

The first 5 terms of the sequence are 3, 8, 14, 30, 58.

marishachu [46]

Answer:

Both answers are correct

Step-by-step explanation:

both y = 1 - 3/2x and y = 1 + -3/2x are correct answers, it is just that y= 1 - 3/2x is the simpler version. Adding a negative number is the same as subtracting a positive.
