Find the area of this rhombus

Mathematics

Answer: SECOND OPTION.

Step-by-step explanation:

You can calculate the area of the rhombus with this formula:

A=\frac{d_1*d_2}{2}

Where d_1 and d_2 are the lengths of the diagonals.

You can observe in the figure that the length of each diagonal is:

d_1=4in+4in=8in\\d_2=8in+8in=16in

Now you can substitute the lenghts of the diagonals into the formula. Therefore, the area of this rhombus is:

 A=\frac{(8in)(16in)}{2}

 A=\frac{128}{2}

 A=64in^2

<h2>Hello!</h2>

The answer is:

The area of the rhombus is equal to 64 squared inches.

area=64in^{2}

<h2>Why?</h2>

Since we already know half of the length of the diagonals of the rhombus, we can calculate the area of the rhombus using the following formula:

area=\frac{diagonal_{1}*diagonal_{2}}{2}

From the image we can see that:

diagonal_{1}=8in+8in=16in

diagonal_{2}=4in+4in=8in

So, substituting, we have:

area=\frac{16in*8in}{2}=\frac{128in^{2} }{2}=64in^{2}

Hence, we have that the area of the rhombus is equal to 64 square inches.

Have a nice day!

Predict The cost of a school photo package includes $40 for the photo shoot, plus the
Alex_Xolod [135]

Answer:

1. Linear; 2. C = 2.50x + 40  

Step-by-step explanation:

1. Prediction

Yes, it is a linear function, because each additional photo adds the same amount to the cost.

2. Equation

         Let C = the cost of the photo package

         and x = the number of photos

Then 2.50x = the cost of the photos

    And $40 = cost of photo shoot

      Then C = 2.50x + 40

The figure below shows that the graph of your equation is a straight line.

I know that is my answer but how do I work it out on notebook paper

'karen is making 14 different kinds of greeting cards she is making 12 of each kind how many greeting cards does she making'

 ok so that is multiplication

14 times 12 since it is 12 of each and 14 of them so
14 times 12=


do you guys still do multiplication by the tower meathod or such if so, here it is

14
<span><u>12 x</u>
</span>

so it is
if you had
     a    b
     <u>c</u><span><u>    d x</u></span>
     (ad)(bd)
<u>(bc)(ac)        +</u>
result

first you do
2 times 4 then place it below the 2

14
<span><u>12 x</u>
</span> 8

then you do 2 times 1 then place it below

14
<span><u>12 x</u>
</span>28

then you move on the the one

1 times 4

14
<span><span><u>12 x</u>
</span>28
4

then 1 times 1<span>

</span></span>  14
<span><span>  <u>12 x</u>
</span>  28
14
</span>
then we add

  14
<span><span>  <u>12 x</u>
</span>  28
<u>14    +</u></span>

It appears that people who are mildly obese are less active than leaner people. One study looked at the average number of minute
NemiM [27]

Answer:

a) 10.93% probability that the mean number of minutes of daily activity of the 5 mildly obese people exceeds 420 minutes.

b) 99.22% probability that the mean number of minutes of daily activity of the 5 lean people exceeds 420 minutes.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean \mu and standard deviation \sigma, a large sample size can be approximated to a normal distribution with mean \mu and standard deviation \frac{\sigma}{\sqrt{n}}.

Normal probability distribution

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Mildly obese

Normally distributed with mean 373 minutes and standard deviation 67 minutes. So \mu = 373, \sigma = 67

A) What is the probability that the mean number of minutes of daily activity of the 5 mildly obese people exceeds 420 minutes?

So n = 5, s = \frac{67}{\sqrt{5}} = 29.96

This probability is 1 subtracted by the pvalue of Z when X = 410.

Z = \frac{X - \mu}{s}

Z = \frac{410 - 373}{29.96}

Z = 1.23

Z = 1.23 has a pvalue of 0.8907.

So there is a 1-0.8907 = 0.1093 = 10.93% probability that the mean number of minutes of daily activity of the 5 mildly obese people exceeds 420 minutes.

Lean

Normally distributed with mean 526 minutes and standard deviation 107 minutes. So \mu = 526, \sigma = 107

B) What is the probability that the mean number of minutes of daily activity of the 5 lean people exceeds 420 minutes?

So n = 5, s = \frac{107}{\sqrt{5}} = 47.86

This probability is 1 subtracted by the pvalue of Z when X = 410.

Z = \frac{X - \mu}{s}

Z = \frac{410 - 526}{47.86}

Z = -2.42

Z = -2.42 has a pvalue of 0.0078.

So there is a 1-0.0078 = 0.9922 = 99.22% probability that the mean number of minutes of daily activity of the 5 lean people exceeds 420 minutes.
