the monthly budget for the front of the house is $18,000. you spent 9% of the budget on fresh flowers. How much did you spend on
Kipish [7]

To find how much was spent on fresh flowers, we just multiply 9% to the monthly budget, which is $18,000.

To multiply a percent to a number, we must first turn the percent into a decimal. Just divide the percent by 100 to get the decimal form. 9% is 0.09.

0.09 \times 18000 = 1620

$1620 was spent on fresh flowers (that's quite a lot of money!)

Hannah claims that people who live in southern states spend 9 hours more per week outside than do people in northern states. She
Levart [38]

Answer:

B. Hannah is likely to be incorrect because 9 is not contained in the interval.

Step-by-step explanation:

She construct a 99% confidence interval for the difference between means and gets the interval (0.4, 8.0).

This means that there is 99% confidence that the true difference between means is within this interval.

The left 1% corresponds to the tails of the distribution: there is 0.5% probability that the difference between means is below 0.4 and 0.5% probability that the difference between means is above 8.0.

As she claims that 9 hours is the true difference, we can say that there is less than 0.5% that she is correct. In others words, is likely to be incorrect.

Elza [17]

Answer:

The slope is -1/3 and the y-intercept is (0, 2).

Step-by-step explanation:

2x+6y=12

6y=12-2x

6y=-2x+12

y=-2/6x+12/6

y=-1/3x+2

y=mx+b where m=slope and b=y-intercept
