Answer:

LCM = 11

Step-by-step explanation:

LCM means least common multiple. We have to find the LCM of two numbers 2.2 and 5.

To get the LCM we will find the factors of 2.2 and 5 first an then multiply common and uncommon factors.

factors of 2.2 = 2×1.1

factors of 5 = 5 (its a prime number)

Here we have all uncommon factors so we will multiply them.

Now LCM of these numbers = 2×(1.1)×5 = 11

So, the answer is LCM of 2.2 and 5 is 11.

The correct answer is:

Explanation:

To find the LCM, we first find the prime factorization of each number:

$2.2=2\times1.1 \\ \\5=5\times 1$

We look for common factors first. There are none, except for 1, which is a factor of every number. Next we multiply the uncommon factors:

2(5)(1.1) = 10(1.1) = 11

The LCM is 11.

Sloan [31]

Answer: 9h + 20 = 62

Step-by-step explanation:

he has 20 dollars now he needs 42 more so 9h is how much he earns multiplied by h how many hours he needs to work and you would add 20 onto that for the money he already saved and set that equal to the amount he needs

Consider random samples of size 80 drawn from population A with proportion 0.48 and random samples of size 66 drawn from populat

gogolik [260]

Answer:

Standard error = 0.070

Step-by-step explanation:

Formula for the standard error of the distribution of differences in sample proportions is;

σ_(A - B) = √((p_a^(1 - p_a^)/n_a) + (p_b^(1 - p_b^)/n_b))

We are given;

p_a^ = 0.48

n_a = 80

p_b^ = 0.13

n_b = 66

Thus;

σ_(A - B) = √((0.48(1 - 0.48)/80) + (0.14(1 - 0.13)/66))

σ_(A - B) = √0.00496545455

σ_(A - B) = 0.070

For an angle θ with the point (−5, −12) on its terminating side, what is the value of cosine?

viva [34]

Answer:

option C. $-\frac{5}{13}$

Step-by-step explanation:

we have that

The point (-5,-12) belong to the III quadrant

The value of the cosine is negative

Applying the Pythagoras Theorem

Find the value of the hypotenuse

$h^{2}=5^{2}+12^{2}\\ h^{2} =25+144\\ h^{2}=169\\h=13\ units$

The value of cosine of angle θ is the ratio between the side adjacent to angle θ and the hypotenuse

$cos(\theta)=-\frac{5}{13}$

-845 degree coterminal angle

meriva

Check the picture below.

with negative angles, we go "clockwise", the same direction a clock hands move.

so -360-360-125 = -845.

so as you see in the picture, you go around twice, and then a little bit more, an extra 125°, landing you at -125°, or its positive counterpart, 235°.

What is the absolute value of -3 1/2?

Lana71 [14]

Answer:

The absolute value of -3 1/2 is 3 1/2.

Step-by-step explanation:

The absolute value of a number is its distance from 0.

In this case the absolute value of -3 1/2 is 3 1/2.

Another way to write is I-3 1/2I
