Find z for the following proportion: z/9= 2/3

Mathematics
1 answer:
serg [7]3 years ago
4 0
Cross multiplication will help find the value of x 
\frac{z}{9} = \frac{2}{3} 



9*2=18 
3*z=3z 

Now we have :
3z=18 
Divide both sides by 3 to isolate z 

Final answer: z=6

LuckyWell [14K]

Answer:

d. H0 : pˆ = .6, Ha: pˆ > .6

Step-by-step explanation:

Given that a minister claims that more than 60% of the adult population attends a religious service at least once a month.

Here the subject of interest about a proportion of adult population who attends a religious service at least once a month.

The claim is  this proportion is greater than 60% and we want to check  whether this claim is true.

Hence hypotheses would be for proportion only and not mean.

Since population proportion is to be checked we use p hat

Correct answer is

d. H0 : pˆ = .6, Ha: pˆ > .6

Ruchi travelled 149 cm 415 in a week How much distance did she travel in a day​
tankabanditka [31]

Answer:

171.85 cm

Step-by-step explanation:

Given data

We are given that the distance = 149 cm 415in

Let us mark the units uniform by converting inches to cm

1 inches = 2.54cm

415 inches= x cm

cross multiply

x= 415*2.54

x= 1054.1 cm

Hence the total distance in cm is 1054.1+149= 1203cm

If in 7 days he travels 1203cm

in 1 day he will travel x cm

cross multiply

7x= 1203

divide both sides by 7

x= 1203/7

x= 171.85 cm

Genuinely confused please help
sammy [17]

Answer: $49,305.56

Step-by-step explanation:

A(t)=a(1+r)^t (its subtraction if the thing decreases)

A(t)=amount after t time periods

t=number of time periods

a=initial amount

r=rate of growth (can’t be a percent, change by moving two decimal places)

A(t)=32000(1+0.155)^3

Hey:) can you please help me posted picture of question
AnnZ [28]
Answer:
x⁴ + 6x² + 9

Explanation:
To answer this question, we will multiply each term from the first bracket by each term from the second bracket and then combine like terms to get the final expression.

This can be done as follows:
(x² + 3)(x² + 3)
x²(x²) + x²(3) + 3(x²) + 3(3)
x⁴ + 3x² + 3x² + 9
x⁴ + 6x² + 9

Hope this helps :)

Given the sequence 34, 42, 50,58, 66.. find the recursive formula & explicit formulas
Marizza181 [45]

Sequence: 34, 42, 50, 58, 66

Since the difference between consecutive terms is 8, we deduce it is an arithmetic sequence, the recursive formula would be:

a_n=a_{n-1}+8

Given that the first term is 34 and the common difference is 8, the explicit formula would be:

a_n=34+(n-1)\cdot8
