Answer:
Step-by-step explanation:
area of triangle =B*H/2
107.16=4.7*H/2
107.16*2=4.7*H
214.32/4.7=H
46.6=H
Answer:
4
Step-by-step explanation:
it takes 15 mins to do 1 mile (3 times 5) and 60 mins divided by 15 would be 4 . so 4 miles
1) Given equation: x/5 + 9 = 11
2) Subtract from both sides of the equation 9 (use Subtraction Property of Equality):
x/5+9-9=11-9,
x/5=2.
3) Unknown variable is dividend, 5 is divisor and 2 is quotient. To find unknown dividend you should find the product of divisor and quotient or in another words use the Multiplication Property of Equality:
x=5·2,
x=10.
These three consecutive steps show you that correct choice is B.
Answer: correct choice is B.
Answer:
40%
Step-by-step explanation:
6/15=2/5=4/10=40%
Answer:
There is not enough evidence to support the claim that the bags are under filled.
Step-by-step explanation:
Given :
Population mean, μ = 433
Sample size, n = 26
xbar = 427
Variance, s² = 324 ; Standard deviation, s = √324 = 18
The hypothesis :
H0 : μ = 433
H0 : μ < 433
The test statistic :
(xbar - μ) ÷ (s/√(n))
(427 - 433) / (18 / √26)
-6 / 3.5300904
T = -1.70
The Pvalue :
df = 26-1 = 25 ; α = 0.05
Pvalue = 0.0508
Since Pvalue > α ; WE fail to reject the Null and conclude that there is not enough evidence to support the claim that the bags are underfilled
