Answer:

(2n+1)(n+7)

Step-by-step explanation:

Here we are given the quadratic expression:

2n^{2}+15n+7

Now we can use AC method to factorise it.

IN this method we first have to multiply 2 and 7.

2 multiplied by 7 equals 14.

Now we have to find two possible factors of 14 which add up to give 15.

Two such possible factors of 14 are 14 and 1.

So now we replace 15n by 14n+1n.

Rewriting the expression,

2n^{2}+14n+1n+7

Factoring by grouping, we have

2n(n+7)+1(n+7)

(2n+1)(n+7)

So the final factored form of the trinomial is

(2n+1)(n+7)

Answer:

= −0.26

= 0.4219

Step-by-step explanation:

Given:

Sample1:  98.1  98.8  97.3  97.5  97.9

Sample2: 98.7  99.4  97.7  97.1  98.0

Sample 1           Sample 2              Difference d

98.1                        98.7                       -0.6  

98.8                       99.4                       -0.6

97.3                        97.7                       -0.4

97.5                        97.1                         0.4

97.9                        98.0                       -0.1

To find:

Find the values of  and

d overbar ( )  is the sample mean of the differences which is calculated by dividing the sum of all the values of difference d with the number of values i.e. n = 5

= ∑d/n

= (−0.6 −0.6 −0.4 +0.4 −0.1) / 5

= −1.3 / 5

= −0.26

s Subscript d is the sample standard deviation of the difference which is calculated as following:

= √∑( - )²/ n-1

=

√

   =  √ (−0.6 − (−0.26 ))² + (−0.6 − (−0.26))² + (−0.4 − (−0.26))² + (0.4 −  

                                                                    (−0.26))² + (−0.1 − (−0.26))² / 5−1

=  

=

=

= 0.4219

= 0.4219

Subscript d ​represent

μ represents the mean of differences in body temperatures measured at 8 AM and at 12 AM of population.

Inequality Word Problems<br><br> 100 POINTS!!!
Rina8888 [55]

Answer:

1. 4 nights

2. $154

Step-by-step explanation:

1. The airfare is a fixed cost, and the cost of staying at the hotel for n nights is 98 * n. So, we add this up: 478 + 93n. This cost can be <em>no more than</em> 850 because that's Jenna's budget limit. So, we have:

478 + 93n ≤ 850

Subtract 478 from both sides:

93n ≤ 372

Divide by 93:

n ≤ 4

The maximum number of nights is 4 nights.

2. Abigail currently has $45 and she needs m more dollars in order to achieve her goal of <em>at least</em> $199. Seeing "at least", we know that we need to use the ≥ sign:

45 + m ≥ 199

Subtract 45 from both sides:

m ≥ 154

Abigail still needs at least $154.

Hope this helps!

20 points! Simplify: 2y(2y+3yx^{2} )-y^{2} (3-y) please show work!
arlik [135]

Answer:

8x2y - 6x2 - 8xy2 - y2

Step-by-step explanation:

Equation at the end of step  1  :

 (((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-(3•(y2)))-((((x2)+(y2))+(8x•(y2)))-3y2)

Step  2  :

Equation at the end of step  2  :

 (((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-(3•(y2)))-((((x2)+(y2))+23xy2)-3y2)

Step  3  :

Equation at the end of step  3  :

 (((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-3y2)-(x2+8xy2-2y2)

Step  4  :

Equation at the end of step  4  :

 (((((5•(x2))•y)-(5•(x2)))+3x2y)-3y2)-(x2+8xy2-2y2)

Step  5  :

Equation at the end of step  5  :

 (((((5•(x2))•y)-5x2)+3x2y)-3y2)-(x2+8xy2-2y2)

Step  6  :

Equation at the end of step  6  :

 ((((5x2•y)-5x2)+3x2y)-3y2)-(x2+8xy2-2y2)

Step  7  :

Final result :

 8x2y - 6x2 - 8xy2 - y2
