The question is in the picture

Answer:

0.21186

Step-by-step explanation:

We solve the above question using the z score formula.

z = (x-μ)/σ, where

x is the raw score = 3100g

μ is the population mean = 3500g

σ is the population standard deviation = 500g

z = 3100 - 3500/500

z = -0.8

Probability value from Z-Table:

P(x<3100) = 0.21186

The probability that a baby is born that weighs less than 3100g is 0.21186

The sum of the measures of the interior angles of a decagon (10 sided polygon) is 1,440

Step-by-step explanation:

Answer:

14.6

Step-by-step explanation:

It would be 14.6 because 14.6 is basically 14.60

So you would compare 14.16 to 14.60

Answer:

No

Step-by-step explanation:

If you try to multiply the 2:4 to change it to 5:6 , you can't because 5 is an odd number and 2 is and even

Answer:

$432.18

Step-by-step explanation:

Time and a half = 50% more pay rate / 1.5*6.86 = $10.29 per hour

Double time = 2*6.86 = $13.72 per hour

Rest of the time => At regular rate

Total Amount = 10(10.29) + 4(13.72) + (54 - 10 - 4)(6.86)

                       = 10(10.29) + 4(13.72) + (40)(6.86)

                       = $ 432.18

Answer:

so 10 hours was 1,5 time and 4 hours was 2 (double) time Her regular rate is $6,86/h so 10 h with 1,5 time make 10*1,5 = ? and 4 h with 2 time make 4*2 = ? total how much you get multiplie by 6,86 and will get in this way easy sure the correct answer.

Answer:

You first want to divide 210 by 50 2/3. once you do that you will get 35/251 or 0.13944

Now you should be able to make about $44 dollars

Answer:

15% of $68 is $10.2

$68 + $10.2 = $78.2

The retail price is $78.20

Answer: 95

Step-by-step explanation: All supplementary angles always have to equal 180 degrees which means that you have to only do 180-85 and boom- 95- that is ur answer. Plz mark Brainliest:).

Answer:

c is the answer you will get you answer as a rational number (hope I'm not wrong)

Answer:

5/6 or 0.83

Step-by-step explanation:

5 ÷ 6 = 0.83 or 5/6

28^2=784

29^2=841

784<830<841

therefore sqrt784<sqrt830<sqrt841

therefore 28<sqrt830<29

Done!

Answer:

11k^2 (k - 7)(k - 1)

Step-by-step explanation:

The highest common factor is

11k^2

Using the distributive property we get at least 2 factors.

11k^2 ( k^2 - 8k + 7)

The second factor reduces yet again.

11k^2 (k - 7)(k - 1)

Answer:

11k^2(k−7)(k−1)

Step-by-step explanation:

11k^4 − 88k^3 + 77k^2

Factor out 11.

11(k^4-8k^3+7k^2)

Consider k^4-8k^3+7k^2. Factor out k^2.

k^2(k^2−8k+7)

Consider k^2 −8k+7. Factor the expression by grouping. First, the expression needs to be rewritten as k^2+ak+bk+7. To find a and b, set up a system to be solved.

a+b=−8

ab=1×7=7

Since ab is positive, a and b have the same sign. Since a+b is negative, a and b are both negative. The only such pair is the system solution.

a=−7

b=−1

Rewrite k^2−8k+7 as (k^2−7k)+(−k+7).

(k^2−7k)+(−k+7)

Factor out k in the first and −1 in the second group.

k(k−7)−(k−7)

Factor out common term k−7 by using distributive property.

(k−7)(k−1)

Rewrite the complete factored expression.

11k^2(k−7)(k−1)

Answer:

Find the prime factorization of 58. 58 = 2 × 29.

Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM: LCM = 2 × 2 × 2 × 2 × 2 × 2 × 29.

LCM = 1856.

Step-by-step explanation:

Answer:

(x²+1)(x-3)

Step-by-step explanation:

Factorize x³ + x - 3x² -3​

x³-3x²+x-3

Factorize

x²(x-3)+1(x-3)

= (x²+1)(x-3)

Hence the factorized form is (x²+1)(x-3)

Equation = 4m=16

Answer= 4m=16

m=16/4 = 4

So Tyrone has 4 model planes.

Don't know if its correct

Answer:

Step-by-step explanation:

In order to simplify we do the following...

[tex]5y + \frac{5}{14} + 9n + \frac{2}{14} + 2y - 3n = (5y +2y) +(\frac{5}{14}+ \frac{2}{14}) + (9n - 3n) = 7y + \frac{1}{2} + 6n[/tex]

Answer:

This expression can be simplified to 7y + 6n + 1/2

Step-by-step explanation:

You can find this by grouping like terms and adding them together.  Starting with the expression we're given:

5y + 5/14 + 9n + 2/14 + 2y - 3n

Let's make it easier by grouping like terms:

(5y + 2y) + (9n - 3n) + (5/14 + 2/14)

Now we'll add them together:

7y + 6n + 7/14

And finally, we can simplify that fraction by factoring 7 out of both the numerator and denominator:

7y + 6n + 1/2

And now we have the final answer.
