Answer:

<h2><em><u>16h2</u></em><em><u> </u></em><em><u>-</u></em><em><u> </u></em><em><u>4h</u></em><em><u> </u></em><em><u>-</u></em><em><u> </u></em><em><u>42</u></em></h2>

Step-by-step explanation:

(4h + 6)(4h − 7)

= 4h(4h - 7) + 6(4h-7)

= 16h2 - 28h + 24h - 42

= <em><u>16h2 - 4h - 42 (Ans)</u></em>

A sample of 5 strings of thread is randomly selected and the following thicknesses are measured in millimeters. Give a point est
xxTIMURxx [149]

Answer:

Point estimate for the population variance = 3.92 * 10^{-3} .

Step-by-step explanation:

We are given that a sample of 5 strings of thread is randomly selected and the following thicknesses are measured in millimeters ;

       X                       X - Xbar                                         (X-Xbar)^{2}

      1.13            1.13 - 1.188 = -0.058                                 3.364 * 10^{-3}

      1.15            1.15 - 1.188 = -0.038                                 1.444 * 10^{-3}    

      1.15            1.15 - 1.188 = -0.038                                 1.444 * 10^{-3}

      1.24           1.24 - 1.188 = 0.052                                 2.704 * 10^{-3}

      1.27           1.27 - 1.188 = 0.082                               <u>  6.724 * </u>10^{-3}<u>    </u>

                                                                    \sum (X-Xbar)^{2} <u>= 0.01568   </u>

Firstly, Mean of above data, Xbar = \frac{\sum X}{n} = \frac{1.15+1.24+1.15+1.27+1.13}{5} = 1.188

Point estimate of Population Variance = Sample variance

                                                               = \frac{\sum (X-Xbar)^{2}}{n-1} = \frac{0.01568}{4} = 3.92 * 10^{-3} .

Therefore, point estimate for the population variance = 3.92 * 10^{-3} .

In expansion of (2x+1)(x^2+px+4), the coefficient of x is twice the coefficient of x^2.
Brilliant_brown [7]

You're probably supposed to find the value of p and not x, which is impossible to do.

Expanding gives

(2x+1)(x^2+px+4)=2x^3+(1+2p)x^2+(8+p)x+4

We're told that

8+p=2(1+2p)

which we can use to solve for p:

8+p=2+4p

6=3p

\boxed{p=2}

a middle school had 600 students and 34% of them are in the 8th grade one fourth walk to school how many walk to school
Delvig [45]

Answer:

Step-by-step explanation:

basic facts:

34% is the same as 34/100

the word 'of' in maths also means multiply

34% of 600 is the same as 34/100 * 600, which is 204

a quarter of 204 is the same as 1/4*204, which is 51

hopefully this helps!!
