Matt thinks that he has a special relationship with the number 4. In particular, Matt thinks that he would roll a 4 with a fair

6-sided die more often than you'd expect by chance alone. Suppose pp is the true proportion of the time Matt will roll a 4.
Required:
a. State the null and alternative hypotheses for testing Matt's claim.
b. Now suppose Matt makes n = 46 rolls, and a 2 comes up 10 times out of the 46 rolls. Determine the P-value of the test.

Answer:

Step-by-step explanation:

Matt thinks that he has a special relationship with the number 2. In particular, Matt thinks that he would roll a 2 with a fair 6-sided die more often than you'd expect by chance alone. Suppose p is the true proportion of the time Matt will roll a 2.

(a) State the null and alternative hypotheses for testing Matt's claim. (Type the symbol "p" for the population proportion, whichever symbols you need of "<", ">", "=", "not =" and express any values as a fraction e.g. p = 1/3)

H0 =  

Ha =

(b) Now suppose Matt makes n = 46 rolls, and a 2 comes up 10 times out of the 46 rolls. Determine the P-value of the test:

P-value = ( u figure it out) u got it

IS IT (A , B ) CAN SOMEONE HELP PLEASE !!!!!!!!!!!!!!!!!

Answer: 1% is your answer

It's (1/100) * 100 or 1% is the percentage strength of a 1:100 solution.

Step-by-step explanation:

l NOTE:

l To change ratio strength to percent strength, it is

sometimes convenient to "convert" the last two zeros in

a ratio strength to a percent sign (%),

l change the remaining ratio to a common fraction, and

then to a decimal fraction in expressing percent.

l Examples:

l 1:100 =1/1% = 1%

l 1:200 = ½% = 0.5%

l 3:500 = 3/5% = 0.6%

l 1:2500 = l/25% = 0.04%

l 1:10,000 = 1/100% = 0.01%

Answer:

DE=5*8=40

Step-by-step explanation:

DE+EF=DF

5x+17x-20=20x-4

22x-20=20x-4

22x-20x=-4+20

2x=16

x=16/2

x=8

DE=5x

DE=5*8=40

The current in a stream moves at a rate of 7 mph. If a boat travels 98 miles downstream in the same time that it takes to travel
JulijaS [17]

If the current in a stream moves at a rate of 7 mph. If a boat travels 98 miles downstream in the same time that it takes to travel 49 miles upstream then the speed of the boat in still water is 21 miles per hour.

<h3>What is speed?</h3>

Speed is the distance covered by an object in a certain time period. It is also known as velocity. The formula of speed is as follows:

Speed=Distance/ Time.

<h3>How to calculate speed?</h3>

We have been given that the speed of stream is 7miles per hour.

Let v be the speed of the boat, and t the time to travel

98=t*(7+v) (1)

49=t(v-7) (2)

(1)+(2) => 2tv=147

7t+(49+7t)=98

14t+49=98

14t=49

t=49/14

t=7/2

Put the value of t in equation 1 to get the value of v:

98=t(7+v)

98=7/2(7+v)

196/7=7+v

28=7+v

v=28-7

v=21

Hence if the current in a stream moves at a rate of 7 mph. If a boat travels 98 miles downstream in the same time that it takes to travel 49 miles upstream then the speed of the boat in still water is 21 miles per hour.
