Alisa buys a watermelon every year. The first time she bought a watermelon, it cost $2.50. She notices the price is getting more

expensive, at a rate of 3% per year. Alisa sketches a graph of the situation, labeling the y-intercept and the point representing the price in Year 4. Which statements are true?
The point ​ (4, 2.62)(4, 2.62) ​ is on the graph.The graph decreases from left to right.The point  (4, 2.81)(4, 2.81)   is on the graph.The graph has an x-intercept and a y-intercept.The graph has a y-intercept only.The graph increases from left to right.

This is the exponential function:
y = 2.50 * 1.03^x
For x = 4:
f ( 4 ) = 2.50 * 1.03^4 = 2.50 * 1.1255 = 2.81
Answer:
- The point ( 4, 2.81 ) is on the graph.
- The graph has a y- intercept only.
- The graph increases from left to right.

1. Average Senior High School annual cost of tuition fee for all private schools in Cavite last year was 46,300 a random sample
anygoal [31]

Answer:

Step-by-step explanation:

H0 : μ = 46300

H1 : μ > 46300

α = 0.05

df = n - 1 = 45 - 1 = 44

Critical value for a one tailed t-test(since population standard deviation is not given).

Tcritical = 1.30

The test statistic :(xbar - μ) ÷ (s/sqrt(n))

The test statistic, t= (47800-46300) ÷ (5600√45)

t = 1500

t = 1500 / 834.79871

t = 1.797

The decision region :

Reject H0: if t value > critical value

1. 797 > 1.30

Tvalue > critical value ; We reject H0

Hence, there is sufficient evidence to conclude that cost has increased.

First look at the difference of the items sold between the 2 people. Clearly Lizzie sold 9 more boxes of peaches and earned 162 more dollars. We can solve and get that each box of peaches are worth 18 dollars. Then use what we found out --> 4 boxes of apples+1 boxes of peaches = 54 dollars. so 4 boxes of apples are worth 54-18=36 dollars. and thus each box of apples are worth 9 dollars.

Answer: each box of apples are wroth 9 dollars and each box of peaches are wroth 18 dollars. Done!

The circular rug has the diameter of 8.2 feet .which measures closest to the circumference of the rug in feet
shutvik [7]

Answer:

8.2pi

Step-by-step explanation:

Hi there!

If the diameter of the rug is 8.2, the radius is 4.1.

The formula for circumference of a circle is 2*pi*r

We'd just plug in 4.1 for r.

2*pi*4.1=8.2pi

Hope this helped! Have a great day! ^u^
