Answer:
The area of the full figure is 60 square inches.
Step-by-step explanation:
There are 4 triangles and one square in this figure. We can start by figuring out the area of the middle square, which would be [tex]6*6=36[/tex] because we know the sides are all 6 inches.
Next, we can look at the triangles and see that their hypotenuses (the longest sides) are all the same length, that being 5 inches. This means that we only need to find the length of the third side and then multiply the area of one triangle by 4 to get the area of all the triangles.
The pythagorean theorem states that in any right triangle, [tex]a^2 +b^2=c^2[/tex], with [tex]c^2[/tex] being the length of the hypotenuse. Since we know the length of the hypotenuse is 5 and one of the legs of the triangle is 4, we can insert this into the equation: [tex]a^2+4^2=5^2[/tex], which when simplified all the way gives us that [tex]a=3[/tex].
Since a right triangle is half of a rectangle, the easiest way to find the area of the triangle is to multiply the measures of the two legs together and then divide by two: [tex](3*4)/2=6[/tex]. Therefore, we know that each triangle in the picture has an area of 6.
Finally, you need to add all of the areas together to find the area of the full figure: [tex]36+6+6+6+6=60 in^2[/tex]
The area of the full figure is 60 square inches.
Hope this helps! :)

The amount of money that college students spend on food each week during the academic year is normally distributed with
a mean of $31.28 and a standard devitation of $11.42.
What is the probability that one randomly selected student will spend less than $25 per week on food?
If you randomly select 10 students, what is the probability that their mean will be less than 525?
Answers
Answer:
~ 70 %
Step-by-step explanation:
(31.28 - 25)/ 11.42 means 25 is .5499 S.D. below the mean
z -score = .7088
70.88 % chance of less than = 25 dollars
The required probability for one randomly selected student will spend less than $25 per week on food is 0.2911 and for randomly selected 10 students, what is the probability that their mean will be less than $25 is 0.040.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
a) X = 25 , μ = 31.28 and σ = 11.42
[tex]Z = \frac{X - \mu}{\sigma}\\z = \frac{25 - 31.28}{11.42}\\z = -0.5499[/tex]
Using z score
Now a probability that one randomly selected student will spend less than $25 per week on food is given.
P(x<25) = p(z = -0.5499)
= 0.2911
b) number of sample = 10
standard deviation = 11.42/√10
= 3.611
Herr,
[tex]Z = \frac{X - \mu}{\sigma}\\z = \frac{25 - 31.28}{3.611}\\z = -1.7444[/tex]
Probability (x<25) = p(z = -1.7444)
Using the Z score table,
Probability (x <25) = 0.040
Thus, the required probability for one randomly selected student will spend less than $25 per week on food is 0.2911 and for randomly selected 10 students, what is the probability that their mean will be less than $25 is 0.040.

Which expression is equivalent to 6x² - 7x-20 ?
Answers
Answer:
(3x+4)(2x−5)
Step-by-step explanation:
The first term is, 6x2 its coefficient is 6 .
The middle term is, -7x its coefficient is -7 .
The last term, "the constant", is -20
Step-1 : Multiply the coefficient of the first term by the constant 6 • -20 = -120
Step-2 : Find two factors of -120 whose sum equals the coefficient of the middle term, which is -7 .
-120 + 1 = -119
-60 + 2 = -58
-40 + 3 = -37
-30 + 4 = -26
-24 + 5 = -19
-20 + 6 = -14
-15 + 8 = -7 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -15 and 8
6x2 - 15x + 8x - 20
Step-4 : Add up the first 2 terms, pulling out like factors :
3x • (2x-5)
Add up the last 2 terms, pulling out common factors :
4 • (2x-5)
Step-5 : Add up the four terms of step 4 :
(3x+4) • (2x-5)
Which is the desired factorization

Blood Types A medical researcher wishes to see if hospital patients in a large hospital have the same blood type distribution as
those in the general population. The distribution for the gendral population is as follows: type A, 22%; type B, 28%; type o,
38%; and type AB = 12%. He selects a random sample of 50 patients and finds the following: 11 have type A blood, 9 have type
B, 24 have type o, and 6 have type AB blood.
At a=0.10, can it be concluded that the distribution is the same as that of the general population? Use the critical value method
with tables.
Answers
We can conclude that there is not enough evidence to suggest that the distribution of blood types in hospital patients is different from that of the general population at a significance level of 0.10.
What is hypothesis testing?Hypothesis testing is a statistical method that is used to make decisions about a population based on a sample of data.
It involves testing a null hypothesis (H0) against an alternative hypothesis (Ha) using statistical techniques.
We have,
We need to perform a hypothesis test to determine if the distribution of blood types in hospital patients is the same as that of the general population.
Let's set up the null and alternative hypotheses:
Null hypothesis:
The distribution of blood types in hospital patients is the same as that of the general population.
Alternative hypothesis:
The distribution of blood types in hospital patients is different from that of the general population.
We can use a chi-squared test to test the hypothesis.
First, we need to calculate the expected frequencies for each blood type based on the general population distribution:
Expected frequency of type A = 50 x 0.22 = 11
Expected frequency of type B = 50 x 0.28 = 14
Expected frequency of type O = 50 x 0.38 = 19
Expected frequency of type AB = 50 x 0.12 = 6
Next, we can calculate the chi-squared statistic:
[tex]$\chi^2 = \frac{(11-11)^2}{11} + \frac{(9-14)^2}{14} + \frac{(24-19)^2}{19} + \frac{(6-6)^2}{6} = 2.84$[/tex]
The degrees of freedom for the test is (4 - 1) = 3.
Using a chi-squared distribution table with 3 degrees of freedom and a significance level of 0.10, the critical value is 6.251.
Since the calculated chi-squared value (2.84) is less than the critical value (6.251), we fail to reject the null hypothesis.
Thus,
We can conclude that there is not enough evidence to suggest that the distribution of blood types in hospital patients is different from that of the general population at a significance level of 0.10.

A farmer sells eggs at a market. She offers three different sizes. For any size, the weight of each egg can vary up to 8%.
Calculate the missing values.
Is it possible for an egg to be both large and extra large?
Explain.
Answers
answers:
medium-41.4,48.6
large-55,59.4
extra large-62,57.04
yes it is possible for an egg to be large and extra large, reason: the lightest possible egg for the extra large is 57.04 and the heaviest possible egg for the large is 59.4. Therefore, an egg between the range(57.04_59.4) is both large and extra large
The missing values for Medium egg are 41.4g, 48.6g
for large eggs are 55g, 59.4g,
and extra large eggs are 62g, 57.04g.
What is percent?A percentage is a figure or ratio that can be stated as a fraction of 100. If we need to calculate the percentage of a number, we must divide it by its full value and then multiply it by 100. As a result, the percentage is one part in one hundred. "Per 100" is short for "per percent." It is represented by the symbol "%".
Given table for size and weight of eggs and the weight of each egg can vary up to 8%.
for Medium eggs Advertised weight = 45 g
lightest weight = 45 - 8% of Advertised weight
because Advertised weight is average of lightest weight and heaviest egg weight,
lightest weight = 45 - 45(0.08)
lightest weight = 41.4 g
heaviest egg weight = 45 + 8% of Advertised weight
lightest weight = 45 + 45(0.08)
lightest weight = 48.6 g
missing values for medium egg = 41.4g and 48.6g
For Large egg
lightest weight = 50.6
Advertised weight = 50.6 + 8% of lightest weight
Advertised weight = 50.6 + 50.6(0.08)
Advertised weight = 54.9 = 55g
heaviest egg weight = 55 + 8% of Advertised weight
heaviest egg weight = 55 +55(0.08)
heaviest egg weight = 59.4g
missing values for large egg = 55g and 59.4g
For Extra large egg
heaviest egg weight = 66.96 g
Advertised weight = 66.96 - 8% of heaviest egg weight
Advertised weight = 66.96 - 66.96(0.08)
Advertised weight = 61.6 = 62 g
lightest weight = 62 - 8% of Advertised weight
lightest weight = 62 - 62(0.08)
lightest weight = 57.04 g
missing values for extra large egg is 62g and 57.04 g
Yes, an egg can be large or extra large for the following reasons: The largest egg is 59.4 pounds, while the lightest egg for an extra large is 57.04 pounds. As a result, an egg between 57.04 and 59.4 is both large and extremely large.
Hence the missing values are,
Medium egg are 41.4g, 48.6g
for large eggs are 55g, 59.4g,
and extra large eggs are 62g, 57.04g.
