Answer:

no, x=-3 is not a solution

Step-by-step explanation:

Plug in -3 as x.

5-(-3)<8

Distribute the -1 to the -3.

5+3<8

Add the 5 and 3.

8<8

8 is not less than 8, so -3 is not a solution to the inequality.

Mariana [72]

Answer: 68/67.8 toothpicks

Step-by-step explanation

first convert how many inches 11.3 feet is

11.3 = 135.6 inches

so after you get your number you get your calculator and divide it by how many inches the toothpicks are

135.6 ÷ 2= 67.8

then to get a solid answer you would round it to a whole number

67.8--> 68

so you ether say the rounded number or you cut .2 inches off the last toothpick

(also im not sure if its 11.3ft or 113ft so if so then take away the decimal and do the same math, you'll end up with 678 toothpicks)

If we wanted to create a new 90% confidence interval from a different sample for the proportion of those with a two on one date
slava [35]

Answer: 271

Step-by-step explanation:

The formula we use to find the sample size is given by :-

n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2

, where z_{\alpha/2} is the two-tailed z-value for significance level of (\alpha)

p = prior estimation of the proportion

E = Margin of error.

If prior estimation of the proportion is unknown, then we take p= 0.5 , the formula becomes

n=0.5(1-0.5)(\dfrac{z_{\alpha/2}}{E})^2

n=0.25(\dfrac{z_{\alpha/2}}{E})^2

Given :   Margin of error : E= 0.05

Confidence level = 90%

Significance level \alpha=1-0.90=0.10

Using z-value table , Two-tailed z-value for significance level of 0.10

z_{\alpha/2}=1.645

Then, the required sample size would be :

n=0.25(\dfrac{1.645}{0.05})^2

Simplify,

n=270.6025\approx271

Hence, the required minimum sample size =271
