Insurance adjusters are concerned about the high estimates they are receiving from jocko’s garage. to see if the estimates are unreasonably high, each of 10 damaged cars was taken to jocko’s and to a trusted garage and the estimates recorded. here are the results:

jocko's: 500,1550,1250,1300,750,1000,1210,13 00,800,2500

other: 430,1500,1300,1280,780,870,1120,114 0,650,2290

use the test of hypothesis procedure to investigate the allegation that jocko’s garage over-charges for the car repairs. state the null and alternative hypotheses (h0 and ha) in a sentence and also using proper greek symbol(s) for the parameter(s). show the test statistic calculations with degrees of freedom, and the p-value etc. use significance level value of 5%. state your conclusion in simple language.

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°

answer: i don't understand it

step-by-step explanation: sorry

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
