Answer:
a. $435
b. 33.33%
Step-by-step explanation:
P.S - The exact question is -
Let Clara raised money = x
As given,
Ali raised 20% more than Clara
⇒Ali raised money = 
Also given,
Clara raised
times more than Shan
Clara raised money = Shan raise money +
times shan raired money
⇒Clara raised money =
Shan raised money
⇒Shan raised money =
times Clara
⇒Shan raised money =
x
As given,
Ali raised $58 more than shan
⇒
⇒
⇒
⇒x = (29)(5) = $145
∴ we get
Clara raised money = x = $145
Ali raised money =
= $174
Shan raised money =
x = $116
a.)
Total raised money = $145 + 174 + 116 = $435
b.)
Percentage of money Clara raised =
×100% =
×100% = 33.33%
Answer:
3√29
Step-by-step explanation:
Use the distance formula to determine the distance between the two points.
Distance
They are parallel to one another
Yes. For example x=-1 and y=-1/2
Answer:
since -3.73 is less than 1.645, we reject H₀.
Therefore this indicate that the proposed warranty should be modified
Step-by-step explanation:
Given that the data in the question;
p" = 13/20 = 0.65
Now the test hypothesis;
H₀ : p = 0.9
Hₐ : p < 0.9
Now lets determine the test statistic;
Z = (p" - p ) / √[p×(1-p)/n]
= (0.65 - 0.9) /√[0.9 × (1 - 0.9) / 20]
= -0.25 / √[0.9 × 0.1 / 20 ]
= -0.25 / √0.0045
= -0.25 / 0.067
= - 3.73
Now given that a = 0.05,
the critical value is Z(0.05) = 1.645 (form standard normal table)
Now since -3.73 is less than 1.645, we reject H₀.
Therefore this indicate that the proposed warranty should be modified
