Explanation:
Distribute the outter number into the parenthesis. After distributing you’ll want to multiply the outter number with the numbers that were in the parenthesis individually.
8 • 10
8 • -c
Now find the sum for each then combine like-terms.
8 • 10 = 80
8 • -c = -8c
Remember that a negative times a positive will remain a negative!! Since there are no like-terms we end up with the following equation, 80 - 8c

Answers
Answer:
The answer is below
Step-by-step explanation:
PQRS is a rectangle. The length of rectangle PQRS = 9 cm + b cm = (9 + b)cm
The breadth of PQRS = a. Hence:
Area of PQRS = length * breadth = (9 + b)(a) = 9a + ab
but Area of PQRS = 84 cm²
9a + ab = 84 (1)
In rectangle PXYS, length = QR = a cm, breadth = YS = b cm
Hence area of PXYS = length * breadth = (a)(b) = ab
But Area of PXYS = 21 cm²
ab = 21 (2)
substitute ab = 21 in equation 1:
9a + 21 = 84
9a = 84 - 21
9a = 63
a = 7 cm
ab = 21
7b = 21
b = 3 cm
Therefore a = 7cm, b = 3 cm

1. Average Senior High School annual cost of tuition fee for all private schools in Cavite last year was 46,300 a random sample of costs this year for 45 private schools indicated that the sample mean was 47,800 and a sample standard deviation was 5600 at the 0.10 level of significance, is there sufficient evidence to conclude that the cost has increased?
Solution:
1. State of hypotheses
2. The level of significance, critical region, and df if any
3. Compute for the value of one sample z-test or t-test
4. Decision rule
5. conclusion
Answers
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.
