Answer:

10 pieces

Step-by-step explanation:

Giveb that:

Length of rope = 5 meters

Length per piece of rope cut = 1/2

Number of rope pieces that could be cut out :

Lenght of rope / length per piece cut

5 meters ÷ 1/2 meters

5 * 2 /1

= 10 pieces

Please help .......

Answer:

see explanation

Step-by-step explanation:

Given f(x) then f(x + a) is a horizontal translation of f(x)

• If a > 0 then shift left by a units

• If a < 0 then shift right by a units

Thus g(x) = (x + 3)² is a shift left of 3 units

Given f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then shift up by c units

• If c < 0 then shift down by c units

Thus g(x) = (x + 3)² - 5

represents a 3 unit shift to the left and a shift down of 5 units

Evaluate the function as indicated determine its domain and range.

crimeas [40]

-1<0 so use 2x+1 2(-1)+1=-2+1=-1 -
F(-1) means "Evaluate F(x) when x=-1" Since -1 is less than 0, this means that F(x) = 2x+1. This is because F(x) = 2x+1 when x < 0

The Wanting Recognition (WR) Scale provides a quantitative measure of a person's level of need for approval and sensitivity to s

levacccp [35]

Answer:

99% of the confidence level of the mean WR score for all convicted drug dealers

(37.4544, 40.5456)

Step-by-step explanation:

Step(i):-

Given that the sample size 'n' = 100

Given that the mean of the sample(x⁻) = 39

Given a standard deviation of the sample (σ) = 6

Level of significance = 0.01 or 99%

Step(ii):-

99% of the confidence level of the mean WR score for all convicted drug dealers

$(x^{-} - Z_{0.01} \frac{S.D}{\sqrt{n} } ,x^{-} + Z_{0.01} \frac{S.D}{\sqrt{n} })$

$(39 -2.576 \frac{6}{\sqrt{100} } ,39 + 2.576 \frac{6}{\sqrt{100} })$

(39 - 1.5456 , 39+1.5456)

(37.4544, 40.5456)

Final answer:-

99% of the confidence level of the mean WR score for all convicted drug dealers

(37.4544, 40.5456)
