<h3>Hello there i hope you are having a good day :) your question: The adult skeleton consists of 206 bones. There are 28 bones in the skull and 30 bones in the arms and legs. Out of the 28 skull bones, 14 are facial bones, 6 are ear bones and 8 are cranial bones. How many more bones are there in the arms and legs than in the face?</h3><h3>So firstly a Adults have 206 bones in their bones and a baby is born with 300 more bones but are fused together when the baby grows up. So 206 bones are in the arms and legs which is 120 then there is 28 bone the skull so the answer should be 120 bones all together.</h3><h3>Hopefully this helps you ❤</h3>

First look at the given numbers, especially 123 degrees which if you add up the other side it equals 180 degrees so:
180-123= 57 
Ok now you know two sides of the triangle and you know that all the 3 sides add up to 360 degrees so:
57+75= 132
180-132= 48

What is the result of subtracting the second equation from the first?
dusya [7]

Answer: 11x-8y=-9

Step-by-step explanation:

For this exercise you need to remember:

1) The mulitplication of signs:

(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-

2) By definition, like terms contain the same variables with the same exponent.

Then knowing this, and given the equations:

8x - 4y = -4 and -3x+ 4y = 5

You must subtract the like terms, which means that you must subtract the numerical coefficients of each term.

Then, you get the result is:

8x - 4y = -4\\-3x+ 4y = 5\\...............................................\\8x-(-3x)-4y-4y=-4-5\\8x+3x-8y=-9\\11x-8y=-9

Answer:

Step-by-step explanation:

I think in this question we have to find slope, if so, its y = 10x.

to find the slope just pick two numbers, i chose (2,20) and (7,70) and then put them in the slope formula y2-y1/x2-x1. That gave me 10. I hope its correct. :)

Prove that if AC=DF and AB=DE then BC=EF
Step2247 [10]
In triangle ABC and DEF
AC =DF, [ given ]
AB =DE, [ given ]
angle A = angle D
by SAS
ABC congruent to triangle DFE
so
BC = EF, [ CPCTC]
hence proved

A news report states that the 99% confidence interval for the mean number of daily calories consumed by participants in a medica
expeople1 [14]

Answer:

The sample mean is of 1925 calories.

The margin of error is of 75 calories.

The sample standard deviation is of 109.7992 calories.

Step-by-step explanation:

Sample mean:

The sample mean is the mean value of the two bounds of the confidence interval. So

M = \frac{1850 + 2000}{2} = 1925

The sample mean is of 1925 calories.

The margin of error

Difference between the bounds and the sample mean. So

2000 - 1925 = 1925 - 1850 = 75 calories.

The margin of error is of 75 calories.

Sample standard deviation:

Here, I am going to expand on the t-distribution.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 18 - 1 = 17

99% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 17 degrees of freedom(y-axis) and a confidence level of 1 - \frac{1 - 0.99}{2} = 0.995. So we have T = 2.898

The margin of error is:

M = T\frac{s}{\sqrt{n}}

In which s is the standard deviation of the sample and n is the size of the sample.

Since M = 75, T = 2.898, n = 18

M = T\frac{s}{\sqrt{n}}

75 = 2.898\frac{s}{\sqrt{18}}

s = \frac{75\sqrt{18}}{2.898}

s = 109.7992

The sample standard deviation is of 109.7992 calories.
