Factor 4x^2 + 12x + 5<br><img src="https://tex.z-dn.net/?f=12x%5E%7B2%7D%20%20-%204x%20-%205" id="TexFormula1" title="12x^{2} -
zheka24 [161]

Answer:

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

(6x - 5)(2x + 1).

Step-by-step explanation:

4x^2 + 12x + 5.

Use the 'ac' method:

a * c = 4 * 5 = 20  so we need 2 numbers whose product is 20 and whose sum is +12.:-  2 and 10 look good, so we write:

4x^2 + 2x + 10x + 5

Now we factor by grouping:-

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

= (2x + 5)(2x + 1)   (answer).

12x^2  - 4x  - 5

ac = 12*-5 = - 60  and  we need 2 numbers sum to -4 .  these numbers could be  -10 and + 6:

12x^2 + 6x - 10x - 5

= 6x(2x + 1) - 5(2x + 1)

= (6x - 5)(2x + 1) (answer).

Yuki888 [10]

Answer:

0.0259,0.0406

Step-by-step explanation:

Given that in a poll taken in December 2012, Gallup asked 1006 national adults whether they were baseball fans: 48% said they were. Almost five years earlier, in February 2008, only 35% of a similar-size sample had reported being baseball fans.

a) p is the proportion of national adults who are baseball fans.

b) For 2012 poll, p=0.48

Std error = \sqrt{\frac{pq}{n} } \\=\sqrt{\frac{0.48*0.52}{1006} } \\=0.0158

Margin of error at 90% = 1.645 * std error

= 0.0259

c) Margin of error is the admissible limit on either side of the mean where the sample mean can lie

d) Margin of error would be larger for 99% because critical value 2.58 >1.645

e) Margin of error 99% = 2.58*0.0157\\=0.0406

SVEN [57.7K]

Answer:

Volume of the hemisphere = \frac{2}{3}\pi r^{3}

Step-by-step explanation:

It's a picture of a globe and a globe of the Earth is in the shape of a sphere.

We know equator divides the earth into two equal halves and these equal halves are called as "hemisphere".

Therefore, a line joining the two extreme points of the diameter of the Earth divides the Earth into two hemispheres.

If the radius of the Earth is 'r',

Volume of the hemisphere = \frac{2}{3}\pi r^{3}
