Answer:

(x+1)(2x+5)

Step-by-step explanation:

f(x) = 2x² + 7x + 5

Factor the expression by grouping. First, the expression needs to be rewritten as 2x²+ax+bx+5. To find a and b, set up a system to be solved.

a+b=7

ab=2×5=10

Since ab is positive, a and b have the same sign. Since a+b is positive, a and b are both positive. List all such integer pairs that give product 10.

1,10

2,5

Calculate the sum for each pair.

1+10=11

2+5=7

The solution is the pair that gives sum 7.

a=2

b=5

2x²+7x+5 as (2x²+2x)+(5x+5).

(2x²+2x)+(5x+5)

Factor out 2x in the first and 5 in the second group.

2x(x+1)+5(x+1)

Factor out common term x+1 by using distributive property.

(x+1)(2x+5)

no lm not sure but lm sure$107.97

Step-by-step explanation:

okieee

The total cost is $108.01.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Mary buys a pair of jeans for $24.99, a skirt for $32.99 and a pair of shoes for $49.99.

She has a coupon for 15% off the most expensive item.

And the most expensive item costs $49.99.

That means, 15% of 49.99

15 x 49.99 = $7.4985

So, the total amount 24.99 + 32.99 + 49.99 - 7.4985

= 100.4715

The tax is 7.5%.

That means,

7.5% of 100.4715

7.5 x 100.4715 / 100 = 7.5353625

Now the total cost = 100.4715 + 7.5353625 = 108.0068625

Therefore, $108.01 is the total cost.

The second one is correct

Answer:

Step-by-step explanation:

The answer should be 18 centimeters

If i am wrong I am sorry

The third leg of the right-angle triangle will be 12 cm.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The Pythagoras theorem formula is given as

H² = P² + B²

The hypotenuse of the right-angle triangle is 13 cm and the perpendicular of the right-angle triangle is 5 cm.

Then the measure of the third side (B) of the right-angle triangle will be

13² = 5² + B²

169 = 25 + B²

 B² = 169 - 25

 B² = 144

   B = 12

Thus, the third leg of the right-angle triangle will be 12 cm.

Answer:

They are in conflict.

Step-by-step explanation:

for statement (a) we have child gunshot deaths doubling every year. So if it was 1 death in 1950, it is 2 in 1951, 4 in 1952, 8 in 1953, 16 in 1954. That would make the deaths in 1994 = (deaths in 1950) x 2 x 2 x 2 x 2 ... with 44 factors of 2. That number is over a trillion.

for statement (b) we have child gunshot deaths doubling over a period of 44 years, which might even be true

Answer:

(a) [tex]\bar x= 1.583[/tex] -- Population Mean

(b) [tex]s = 1.032[/tex] --- Population standard deviation

(c) See Explanation

Step-by-step explanation:

Given:

Cigarette tax for 20 regions

Solving (a): The population mean

This is calculated as:

[tex]\bar x = \frac{\sum x}{n}[/tex]

[tex]\sum x = 1.36 + 1.70 + 2.50 + 0.45 + 1.18 + 0.64 + 3.46 + 0.57 + 2.00 + 0.80 + 1.60 +0.98 + 0.36 + 2.24 + 4.35 + 0.62 + 2.70 + 1.78 + 1.53 + 0.84[/tex]

[tex]\sum x = 31.66[/tex]

[tex]n = 20[/tex]

So, we have:

[tex]\bar x= \frac{31.66}{20}[/tex]

[tex]\bar x= 1.583[/tex]

Solving (b): The population standard deviation

This is calculated as:

[tex]s = \sqrt{\frac{\sum( x - \bar x)^2}{n}[/tex]

[tex]\sum (x -\bar x)^2 = (1.36 - 1.583)^2 + (1.70 - 1.583)^2+ (2.50 - 1.583)^2+ (0.45 - 1.583)^2+ (1.18 - 1.583)^2+ (0.64 - 1.583)^2+ (3.46 - 1.583)^2+ (0.57 - 1.583)^2+ (2.00 - 1.583)^2+ (0.80 - 1.583)^2+ (1.60 - 1.583)^2+(0.98 - 1.583)^2+ (0.36 - 1.583)^2+ (2.24 - 1.583)^2+ (4.35 - 1.583)^2+ (0.62 - 1.583)^2+ (2.70 - 1.583)^2+ (1.78 - 1.583)^2+ (1.53 - 1.583)^2+ (0.84- 1.583)^2[/tex]

[tex]\sum (x -\bar x)^2 = 21.29222[/tex]

So:

[tex]s = \sqrt{\frac{21.2922}{20}[/tex]

[tex]s = \sqrt{1.06461}[/tex]

[tex]s = 1.032[/tex]

Solving (c):

Population mean tells the average amount while the standard deviation represents the spread from the calculated mean

Option (4) is correct

Answer:

the third one!

Step-by-step explanation:

Because it says, the SUM of the number, x (or z I can't really see it well) and 1/2, you must add those two together:

1/2 + x

Then it says those two numbers equal to 4, so it would look like this:

1/2 + x = 4

Because you are trying to isolate, and solve for x, you must SUBTRACT 1/2 from both sides of the equal sign:

1/2  +  x  =  4

-1/2            -1/2

1/2 minus 1/2 would result 0, so there would be x by itself. and 4 minus 1/2 would be 3 and a half ( 3  1/2), so x would be  3  1/2

x = 3 1/2
