Answer:
Option C 67 upto 70
Step-by-step explanation:
Given that heights of college women" recorded to the nearest inch: the first two class midpoints are 62.5" and 65.5".
This explains that each class width=Difference between mid values of successive classes ![65.5-62.5 = 3](https://tex.z-dn.net/?f=65.5-62.5%20%3D%203)
Also next class will have midvalue as ![65.5+3 = 68.5](https://tex.z-dn.net/?f=65.5%2B3%20%3D%2068.5)
So next class has mid value as 68.5 and width as 3
i.e. 1.5 each side should be given
So class interval = ![(68.5-1.5, 68.5+1.5)\\=(67, 70)](https://tex.z-dn.net/?f=%2868.5-1.5%2C%2068.5%2B1.5%29%5C%5C%3D%2867%2C%2070%29)
Option c
Answer:
is a trinomial having with:
Step-by-step explanation:
Considering the trinomial
![2x^5+3x^2+3](https://tex.z-dn.net/?f=2x%5E5%2B3x%5E2%2B3)
- Any polynomial with 3 terms is a trinomial, so it is a trinomial.
It is clear that '5' is the highest power of the 'x' variable. so, the polynomial has a degree of 5.
'3' is the constant term. The reason is that any term with no variable is called a 'constant' term. So, '3' is the constant term.
Therefore,
is a trinomial having with:
You need to find the total surface area of the rectangular prism. The top and bottom are 8(6), which equals 48. Since we want both the top and bottom, multiple 48 by 2 to get 96. The we need to calculate the remaining 4 sides. Two of them are 15(6), which is 90. Again, multiply by two since there’s two of those sixes to get 180. Finally, the last two sides are 15(8), which is 120. Add all of these numbers together to get 96+180+120=396. So she will need 396 cm^2 of fabric.
Answer:
4.2×10to the 6th or 4,200,000
Step-by-step explanation:
First you have to know that you are multiplying these two numbers. When you multiply exponents like there you add the matissa's (6&7) and add the exponents.
6×10to the 2 * 7×10to the 3rd
42 × 10to the 2+3
42×10to the 5th
Something else you need to know is your matissa cant be higher than 10
So:
4.2 × 10to the 6th is your answer
