Answer:
5(2 + y)
Step-by-step explanation:
The sum of 2 and y is 2 + y and 5 times this sum is
5(2 + y)
Answer:
78
Step-by-step explanation:
The IQR is quartile 3 - quartile 1. First, we need to find the mean of the dataset, which is 50 -- the fifth number. Then, the median of the dataset on the left of the fifth number is the first quartile, and the median of the dataset on the right is the third. We get Q1 to then be halfway between 30 and 50, or 40, and Q3 to be halfway between 56 and n, so Q3 = (56+n)/2. Since we need Q3-Q1=27, or (56+n)/2-40=27, we have (56+n)/2=67 and 56+n=134, so n = 134-56=78
You can do this by finding a number close to it, and then finding out how to do it.
For example with 63(square root sign), find out what is close to it.
7x7=49 while 8x8=64
Because of this, we now know that it is between 7 and 8 but is also really close to 8.
Our number could be 7.9
Hope this helped!!!
Answer:
Step-by-step explanation:
ans is c) f(x) is a polynominal function. The degree is 5 and the leading coefficient is -7.
x -> ∞, f(x) -> ∞; x -> -∞, f(x) -> -∞
the only ans that follows the above is a) f(x)=7x^9-3x^2-6
correct statments are: c) (1, 6.08) and (3, 0.75) are local extrema for the function and d) (-2, -9.67) is the global minimum for the function.
