Answer: It is C because if you organize the equation numerically the equation is 18x^3+30x^2+12x+10. So it is 18.

Answer: A. $\left[\begin{array}{ccc}29&13\\13&10\\\end{array}\right]$

Step-by-step explanation:

The question is asking us to find the product of the matrices. The key difference is the second A has a little T in the exponent. This T means transpose. You multiply A by the transpose of A. To find the transpose, you turn the rows into columns.

$A^T=\left[\begin{array}{ccc}5&3\\2&-1\\\end{array}\right]$

Now that we have our transpose, we can multiply the matrices.

$\left[\begin{array}{ccc}5&2\\3&-1\\\end{array}\right] \left[\begin{array}{ccc}5&3\\2&-1\\\end{array}\right] =\left[\begin{array}{ccc}5*5+2*2&5*3+2(-1)\\3*5+2(-1)&3*3+(-1)(-1)\\\end{array}\right] =\left[\begin{array}{ccc}29&13\\13&10\\\end{array}\right]$

The best option is C. 0.0823mean = np = 48*1/4 = 12

SD = sqrt(npq) = sqrt(48 *1/4 *3/4) = 3

aplying continuity correction for using a continuous distribution for a discrete one,

"exactly 15" means 14.5 to 15.5

z1= (14.5-12)/3 = 0.833 , z2 = (15.5-12)/3 = 1.167

P(0.833 < z < 1.167) = 0.0808

Answer:

x = 74°

Step-by-step explanation:

Same side interior angles are supplementary meaning they must add up to 180°.

x = 180° - 106°

x = 74°
