Answer:
I can't tell what the triangle is
Step-by-step explanation:
<h3>
Answer:</h3>
- 3,8 kg
- 750 g
- 7,47 g
<h3>
Step-by-step explanation:</h3><h3>3800 g => kg</h3>
(3800 ÷ 1000) kg
= 3,8 kg
<h3>
¾ kg => g</h3>
(3 ÷ 4)kg × 1000
= 0.75 × 1000
= 750 g
<h3>7470 g => kg</h3>
(7470 ÷ 1000) kg
= 7,47 kg
It is 18/20 and in simplest form it is 9/10.
Steps:
1.You have to add all the shirts, 2+7+11. This is 20, this will become your denominator
2. See what portion is NOT BLACK, the non black at 7 and 11, once you add these it becomes 18. 18 is now your numerator.
3. You now have the fraction 18/20 which you can simplify into 9/10
Hope this helps :)
Answer:
The solution to the system of equations will be:
Step-by-step explanation:
Given the system of equations
Multiply 2x-9y=-36 by 7
so the system of equations becomes
Adding both equations
solve -45y = -270 for y
divide both sides by -45
Simplify
For 14x-63y = -270 plug in y = 6
Add 378 to both sides
Simplify
Divide both sides by 14
Simplify
Therefore, the solution to the system of equations will be:
Considering the one-sided p-value, the p-value for a two-sided test would be of 0.20.
<h3>How to find the p-value of a test?</h3>
It depends on the test statistic z, as follows:
- For a left-tailed test, it is the area under the normal curve to the left of z, which is the p-value of z.
- For a right-tailed test, it is the area under the normal curve to the right of z, which is 1 subtracted by the p-value of z.
- For a two-tailed test, it is the area under the normal curve to the left of -z combined with the area to the right of z, hence it is 2 multiplied by 1 subtracted by the p-value of z, which means that <u>the p-value for a two-tailed test is </u><u>twice </u><u>the p-value of a one-tailed test</u>.
In this problem, for the one-tailed test, the p-value is of 0.1, hence the p-value for a two-sided test would be of 0.20.
