The answer should be -19F
Because it would drop by 3 degrees, we know hours (x). -3x. So in this case we know how many hours we are measuring 4. So plug in the number for x and you would get -12F after multiplying, then add that to the -7F to get -19F

Solution :

$H_0: p = 0.5$

$H_a: p > 0.5$

Alpha, α = 0.01

The sample proportion is :

$p'=\frac{x}{n}$

$=\frac{513}{806}$

= 0.636

Test statistics, $z=\frac{p'-p}{\sqrt{\frac{pq}{n}}}$

$z=\frac{0.636-0.5}{\sqrt{\frac{0.5\times 0.5}{806}}}$

$z=\frac{0.136}{0.0176}$

z = 7.727

The p value = 0.00001

Here we observe that p value is less than α, and so we reject the hypothesis $H_0$ .

Therefore, there is sufficient evidence,

An object is traveling at a steady speed of 9 9/10 km/per hour about how long will it take the object to travel 5/1/10 km/per ho

Delicious77 [7]

Answer:

0.52 km

Step-by-step explanation:

We are given that

Speed of object, v= $9\frac{9}{10}km/h$

Speed of object, v= $9+0.9=9.9km/h$

Distance travel by object, s= $5\frac{1}{10}km$

Distance travel by object, s= $5+0.1=5.1km$

We have to find the time taken by object to travel 5 1/10 km.

We know that

$Time=\frac{Distance}{speed}$

Using the formula

Time taken by object to travel 5.1 km = $\frac{5.1}{9.9} hr$

Time taken by object to travel 5.1 km=0.52 hr

serg [7]

Answer:

8

Step-by-step explanation:

the ratio or fraction for this problem would be 1 (gold coin) : 25 (points)

If we want to find out how many gold coins he needs to get 200 points we need to divide 200 by 25.

200/25 : 8

if we want to check our answer do this

1:25

1 x 8 is 8

25 x 8 is 200

Soo... Collin needs to find 8 coins to win 200 points.

hope i helped
