Answer:  Third Option is correct.

Explanation:

Since we have given that

In \frac{3}{4} pound of a spice mix,

Number of cups of cinnamon is given by

\frac{5}{6}

We need to find the number of cup of cinnamon per pound,

For this we will use "Unitary method" ,

So, for 1 pound,

Number of cups of cinnamon is given by

\frac{4}{3}\times\frac{5}{6}=\frac{10}{9}=1\frac{1}{9}

\text{So, there are }1\frac{1}{9}\text{ cups the spice mix contain per pound.}

Hence, Third Option is correct.

In this problem, we explore the effect on the standard deviation of adding the same constant to each data value in a data set. C

Answer:

3.6661

3.6661

A, Adding a constant does nothing to the standard deviation

Step-by-step explanation:

I'm gonna assume s=standard deviation

The standard deviation is just the square root of the second moment minus the first moment squared

Because we were not told otherwise I think it's pretty safe to assume that all events are equally likely

Let's start by calculating the first moment (AKA The mean)

1/5(8+16+14+8+16)= 12.4

Let's then find the second moment

1/5(8²+16²+14²+8²+16²)= 167.2

√(167.2-12.4²)=3.6661

b.

While I could just tell you that adding something to the standard deviation (and the variane as well) doesn't do anything let's calculate it for fun

same process

.2(16+24+22+16+24)= 20.4

.2(16²+24²+22²+16²+24²)=429.6

√(429.6-20.4²)= 3.6661

PLS HELP
Katena32 [7]

Answer:

-30x^2-9x+12  all real numbers

Step-by-step explanation:

f(x) = -6x + 3 and g(x) = 5x + 4

f(x) * g(x) = (-6x + 3) * ( 5x + 4)

FOIL

            = -30x^2 -24x+15x +12

Combine like terms

           =-30x^2-9x+12

The domain is what numbers x can take

There are no restrictions so all real numbers
