Tyana has a collection of hoodies and t-shirts. She has 561 pieces of collected clothing in all. The number of hoodies is twice the number of t-shirts. Find the number of each type of clothing she has.

Answer:

a. -1.35

b. 0.177016

Step-by-step explanation:

According to the question, following data is given

Brown eyes american percentage is 45

Random sample be 80 out of which 30 had brown eyes

Based on the above information

The computation is shown below:

a. The proportion of the sample is

[tex]\bar p = \frac{30}{80}\\\\= 0.375[/tex]

The z value is

[tex]z = \frac{\bar p - p }{\sqrt{\frac{p(1 - p)}{n} } } \\\\\frac{0.375-0.45 }{\sqrt{\frac{0.45(1 - 0.45)}{80} } }[/tex]

= -1.35

b Now the P value is

As z comes -1.35

So, there is a two tailed p value i.e. 0.177016

Answer: 48

Step-by-step explanation:

If 25% of the people in the cafeteria is equal to 12, then you have to work out the value of 100%.

100 divided by 4 is 25.

Therefore, if we times 25 by 4, then we get 100%.

12 times by 4 is 48, meaning there are 48 people in total in the cafeteria.

Answer:

Linda ran at a faster pace on Monday with a speed of 6 miles/hour

Step-by-step explanation:

Rate or Speed = Distance/Time

On Monday, Linda ran 3.5 miles in 35 minutes.

Converting 35 minutes to hours

60 minutes = 1 hour

35 minutes = x

x = 35/60

x = 0.5833333333 hour

Rate or speed = 3.5miles/0.5833333333 hour

= 6 miles/hour

On Tuesday, she ran 3 miles in 40 minutes.

Converting 40 minutes to hours

60 minutes = 1 hour

40 minutes = x

x = 40/60

x = 0.6666666667 hour

Rate or speed = 3miles/0.6666666667 hour

= 4.5 miles/hour

Linda ran at a faster pace on Monday with a speed of 6 miles/hour

(a) 0.00000221    (b) 4.2 x [tex]10^{5}[/tex]

Step-by-step explanation:

(a)  [tex]10^{-6}[/tex] means you need to move the decimal left (because of the negative) 6 spaces. So you have 2.21 move the decimal 6 spaces left and you end up with 0.00000221

(b) If you have 420,000 and you count 5 spaces from the last number, that leaves the decimal inbetween the 4 and 2 so your answer will be 4.2 x [tex]10^{5}[/tex]

Answer:

The range is between 21 and 75

Step-by-step explanation:

"The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side."

Any two sides of of a triangle added together cannot be equivalent to or less than the length of the third side. Knowing this, we can figure out the range. If you add 48 and 27, you get 75.  We know 75 is the top of the range, the length of the third side cannot be 75 or greater. Going the other way, if you assume that the third side is one of the smaller ones, you can identify 48 as the largest value. If you subtract 27 from 48 you get 21, so the length of the third side cannot be 21 or lower.

This gives us the range. Just keep this rule in mind. Hope this helped!

Answer:

The food store used  3 lbs of clusters, 6 lbs of granola, and 3 lbs of raisins.

Step-by-step explanation:

Given that:

A food store makes a 12-lb mixture of granola, clusters, and raisins.

The cost of granola = 1.00 per pound

The cost of clusters = 3.00 per pound

The cost of raisins = 2.00 per pound

Let granola be = g; cluster be c and raisins be r

Then, g + c + r = 12

Similarly, the mixture calls for twice as much granola as clusters.

2c + c + r = 12

3c + r = 12

r = 12 - 3c

2c(1) + 3c + 2r = 21

2c + 3c + 2r = 21

5c + 2r = 21

5c + 2(12 -3c) = 21

5c + 24 - 6c = 21

24 - c  = 21

-c = 21 - 24

c = 3

Thus, cluster c = 3 lbs

granola = 2(c) = 2(3) = 6 lbs

raisins = 12 - 3c

= 12 - 3(3)

= 12 - 9

raisins = 3 lbs

Step-by-step explanation:

I'm not entirely sure what you mean by "from the origin", but hopefully this helps.

The distance formula for a Cartesian coordinate system (your standard x-y graph) is [tex]d=\sqrt{(x1-x2)^{2}+(y2-y1)^{2}}[/tex].

If you're measuring "from the origin", that just means one of your points is (0,0).

For example, if you were to measure between the origin and the point (1,4) your formula would look like this:

[tex]d=\sqrt{0-1)^{2}+(0-4)^{2}}\\d=\sqrt{(-1)^{2}+(-4)^{2}} \\d=\sqrt{1+16} \\d=\sqrt{17}[/tex]

So, the distance between the origin and (1,4) is [tex]\sqrt{17}[/tex].

I hope this helps! Please let me know if you have any other questions!

Answer:

Slope is 4/3

Step-by-step explanation:

We need to turn this into slope intercept form to find the slope,

slope intercept form is y=mx+b, we just need to "rearrange" the problem using reverse operations and get our slope

4x+3y=2      

4x-4x+3y=2-4x  subtract 4x from both sides ⇒ 3y=4x-2

we need to get rid of the 3, so divide both sides by 3

[tex]\frac{3y}{3} =\frac{4x-2}{3}[/tex]        and we get

y=4/3x-2/3

Our slope is 4/3

Answer:

0.2297453

Step-by-step explanation:

Given that :

Total faces of = 12 labeled 1 - 12

Probability of showing a 2 ;

P = required outcome / Total possible outcomes

P(showing a 2) = 1 /12

Hence, probability of not showing a 2 ;

P(showing a 2)' = 1 - 1/2 = 11/12

Probability that atleast one of 3 cubes shows a 2 :

1 - P(none of the cubes shows a 2)

P(none of the cubes shows a 2) =

(11/12 * 11/12 * 11/12) = 0.7702546

1 - 0.7702546 = 0.2297453

This question is based on the probability. Therefore, the probability that at least 1 show as a 2 is 0.22974 if 3 such number cubes are rolled.

Given:

In a certain board game a 12 sided number cube showing numbers 1-12 is rolled.

We need to determined the probability that at least 1 show as a 2, if 3 such number cubes are rolled.

It is given that total faces of = 12 labeled 1 - 12

Now calculating probability of showing a two ;

[tex]Probability = \dfrac{ Required\, outcome }{Total\, possible \,outcomes}[/tex]

[tex]Probability\, of\, showing\,a \,two=\dfrac{1}{12}[/tex]

Hence, probability of not showing a 2 is,

[tex]Probability\, of\, not\,showing\,a \,two=1-\dfrac{1}{12}[/tex]

Now, calculating probability that at least one of 3 cubes shows as a 2 =

1 - P(none of the cubes shows a 2)

[tex]P(none\, of\, the\, cubes\, shows\, a \,2) = \dfrac{11}{12} \times \dfrac{11}{12} \times \dfrac{11}{12} \\\\P(none\, of\, the\, cubes\, shows\, a \,2)=\dfrac{1331}{1728} = 0.770[/tex]

Probability that at least one of 3 cubes shows as a 2 = 1 - 0.770 = 0.22974

Therefore, the probability that at least 1 show as a 2 is 0.22974 if 3 such number cubes are rolled.

Using geometric sequence concepts, it is found that the one which results in a sum of -69,905 is:

D. [tex]\sum_{k = 0}^{9} -\frac{1}{5}(4)^k[/tex]

As a sum, it can be represented by:

[tex]\sum_{k = 0}^{n - 1} a_1(q)^k[/tex]

The result of the sum is:

[tex]S = \frac{a_1(1 - q^n)}{1 - q}[/tex]

Item A:

For this sequence, we have that:

[tex]a_1 = \frac{1}{4} = 0.25, n = 8, q = -5[/tex]

Hence, the sum is:

[tex]S = \frac{0.25(1 - (-5)^8)}{4} = -24414[/tex]

Item B:

For this sequence, we have that:

[tex]a_1 = -\frac{1}{4} = -0.25, n = 12, q = 5[/tex]

Hence, the sum is:

[tex]S = \frac{-0.25(1 - (5)^12)}{-4} = -15258789[/tex]

Item C:

For this sequence, we have that:

[tex]a_1 = \frac{1}{5} = 0.2, n = 11, q = -4[/tex]

Hence, the sum is:

[tex]S = \frac{0.2(1 - (-4)^11)}{3} = 279620.3[/tex]

Item D:

For this sequence, we have that:

[tex]a_1 = -\frac{1}{5} = -0.2, n = 10, q = 4[/tex]

Hence, the sum is:

[tex]S = \frac{-0.2(1 - (4)^10)}{-3} = -69905[/tex]

Hence option D is correct.

Step-by-step explanation:

There does not exist any solution of  as thir graphs do not intersect.

Step-by-step explanation:

We are given that,

The values of the exponential function f(x) are f(1)= 2 and f(2)= 6.

That is, we get,

So, the function f(x) is .

Moreover, the values of the linear function g(x) are g(1) = 2.5  and g(2) = 4.

That is, the slope =  = 1.5

Substituting the slope and point (1,2.5) in the linear equation , where m is the slope, we get,

i.e. b= 1

Thus, the function g(x) is .

Consider,  

i.e.  

Now, the function f(x) is exponentially increasing and the linear function g(x) is increasing between x= 1 and x= 2, but there is no point where the graphs of the functions are intersecting.

Thus, there is no solution of the equation .
