Alternate hypothesis:

What is questioned(higher, lower, different,...) of the null hypothesis

Previously, an organization reported that teenagers spent an average of 4.3 hours per week, on average, on the phone.

This means that the null hypothesis is $H_{0} = 4.3$ .

Raina is on the swim team. Each day she swims 750m . How far does she swim in 5 days?

Sav [38]

1 day = 750 m

1 * 7 = 750 * 7

7 days = 5250 m

Now, since 1 km = 1000 m, this means in order to convert from meters to kilometers you must divide by 1000

5250 / 1000

= 5.25 km

Or, you could do the hard way by going to wolfram alpha / google and typing 5250 m to km.

Hope this helps!

The sum of three numbers is -44.84. One of the numbers is 26.6. The other two numbers are equal to each other. What is the value

docker41 [41]

A+b+c=-44.84

a=26.6
b=c

26.6+b+b=-44.84

2b=-44.84-26.6

b=-35.72

So, a=26.6, b=-35.72, c=-35.72
