5c squared- d squared+3/2c - 4d...c= -1. d= -4​
riadik2000 [5.3K]

For this case we have the following expression:

5c ^ 2-d ^ 2 + \frac {3} {2} c-4d

We must find the value of the expression when:

c = -1\\d = -4

Substituting we have:

5 (-1) ^ 2 - (- 4) ^ 2 + \frac {3} {2} (- 1) -4 (-4) =\\5 (1) -16- \frac {3} {2} + 16 =\\5-16- \frac {3} {2} + 16 =\\-11- \frac {3} {2} + 16 =\\- \frac {25} {2} + 16 =\\\frac {-25 + 32} {2} =\\\frac {7} {2}

Finally, the value of the expression is:

\frac {7} {2}

ANswer:

\frac {7} {2}

Use the frequency table to find the mean number of working TV sets in students' homes. (picture attached)
LenaWriter [7]

The correct option is :  2

<u><em>Explanation</em></u>

For finding the mean number of working TV sets, we need to <u>divide the total number of TV sets by the total frequency</u>.

Now for finding the total number of TV sets, first we will <u>multiply each number of TV sets by it's frequency and then sum up all the results</u>.

So, the total number of TV sets

=(0*1)+(1*8)+(2*9)+(3*4)+(4*3) \\\\  =0+8+18+12+12=50

and total frequency =1+8+9+4+3= 25

Thus, the mean number of working TV sets = \frac{50}{25}=2

Using traditional methods, it takes 9.5 hours to receive a basic flying license. A new license training method using Computer Ai
Aleonysh [2.5K]

Answer:

Step-by-step explanation:

Null hypothesis: u = 9.5hrs

Alternative: u =/ 9.5hrs

Using the t test

t = x-u/sd/√n

Where x is 10hrs, u is 9.5, sd is 1.6 and n is 15

t = 10-9.5 / (1.6/√15)

t = 0.5 / (0.4131)

t = 1.21

In order to make a conclusion, we have to find the p value at a significance level lot 0.1. The p value is 0.2263 which is greater than 0.1. This, we will fail to reject the null hypothesis and conclude that there is not enough statistical evidence to prove that the technique performs differently than the traditional method.
