Answer:

D

Step-by-step explanation:

This is a simple slope question, apply the slope formula

m=(y2-y1)/(x2-x1)

m=(3-7)/(4- -2)

m=(-4)/(6)

simplify

m=-2/3

g A popular theory is that presidential candidates have an advantage if they are taller than their main opponents. Listed are he
stira [4]

Answer:

Step-by-step explanation:

Corresponding heights of presidents and height of their main opponents form matched pairs.

The data for the test are the differences between the heights.

μd = the​ president's height minus their main​ opponent's height.

President's height. main opp diff

191. 166. 25

180. 179. 1

180. 168. 12

182. 183. - 1

197. 194. 3

180. 186. - 6

Sample mean, xd

= (25 + 1 + 12 - 1 + 3 + 6)/6 = 5.67

xd = 5.67

Standard deviation = √(summation(x - mean)²/n

n = 6

Summation(x - mean)² = (25 - 5.67)^2 + (1 - 5.67)^2 + (12 - 5.67)^2+ (- 1 - 5.67)^2 + (3 - 5.67)^2 + (- 6 - 5.67)^2 = 623.3334

Standard deviation = √(623.3334/6 sd = 10.19

For the null hypothesis

H0: μd ≥ 0

For the alternative hypothesis

H1: μd < 0

The distribution is a students t. Therefore, degree of freedom, df = n - 1 = 6 - 1 = 5

The formula for determining the test statistic is

t = (xd - μd)/(sd/√n)

t = (5.67 - 0)/(10.19/√6)

t = 1.36

We would determine the probability value by using the t test calculator.

p = 0.12

Since alpha, 0.05 < than the p value, 0.12, then we would fail to reject the null hypothesis.

Therefore, at 5% significance level, we can conclude that for the population of heights for presidents and their main​ opponents, the differences have a mean greater than 0 cm.

Step-by-step explanation:

let \: the \: let \: the \: length \: be \to \: x \\when \: folded :  it \: becomes \to \:  \frac{x}{2}  \\hence : \to \\  93.5 \times  \frac{x}{2}  = (93.5 - 1) \\ 93.5x = 2(93.5 - 1) \\ 93.5x = 2 \times 92.5 \\ 93.5x = 185 \\ x =  \frac{185}{93.5}  \\  \boxed{x = 1.9786096257 }\\
