Hmmm......
Then, you must be thinking of 19.
Explanation:
Let you numher be x
now
according to question
multiply it by 8 and it becomes 8×x = 8x
Now add 22
so it becomes
8x + 22
now as told in the question take the same number again i.e x for one more time.
multiply it by 6
and you'll get 6x
and after adding 60 you'll get 6x + 60
Now again according to question
8x+ 22 and 6x+60 are same number therefore they must be equal,
8x+22 = 6x+60
Do a little azebra
8x -6x = 60 -22
2x = 38
x = 19.
and Tada, your number is here.
Answer:
(6+8)/2 = 7
Step-by-step explanation:
Answer:
(4, 1)
Step-by-step explanation:
For any rectangle or square located on the axes, match the pairs and find what's missing. 3 -- 3, 4 -- 4. unmatched are 4 and 1. 4 is x because it's missing from x and same for 1 and y.
Answer:
The x and y intercept are (20,0)
Step-by-step explanation:
2x-4y=40—eqn1
-x+2y=-20—eqn2
Make x the subject of eqn2
-x=-20-2y
x=20+2y
plug this into eqn 1
2(20+2y)+4y=40
40+4y+4y=40
8y=40-40
y=0
plug y=0 into eqn2
-x+2(0)=-20
-x=-20
x=20
Answer:
Test statistic Z = 2.1097
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that size of the sample 'n' = 160
Given that mean of the Population(μ) = 5.3pounds/square inch
The Standard deviation of the population(σ) = 0.6
Mean of the sample(x⁻) = 5.4
Level of significance =0.1
<u><em>Step(ii):-</em></u>
Test statistic
Z = 2.1097
<u><em>Final answer</em></u>:-
Test statistic Z = 2.1097
