Which is a better buy, 5 for $4.25 or 8 for $6.88?

Answer and Step-by-step explanation:

To calculate a confidence interval for a proportion:

1) Determine the proportion

[tex]p=\frac{308}{500}[/tex]

p = 0.616

2) A 90% confidence interval has z-score that is 1.645.

3) Calculate margin of error

[tex]ME=\sqrt{\frac{p(1-p)}{n} }[/tex]

where

n is the sample size

So

[tex]ME=\sqrt{\frac{0.616(1-0.616)}{500} }[/tex]

[tex]ME=\sqrt{\frac{0.616(0.384)}{500} }[/tex]

ME = 0.02175

Then the interval is given by

p ± z(ME)

0.62 ± 1.645(0.02175)

0.62 ± 0.035

The interval will be

0.585 < p < 0.655

What this means is that we are 90% confident that the true proportion of Katy Perry's Twitter female followers is between 0.585 and 0.655.

Answer:

23/16

Step-by-step explanation:

23/16+1/16=24/16=3/2

Answer:

(5, 2) & (-4, -9)

Step-by-step explanation:

Use the vertex form, y = a(x − h)² + k, to determine the values of a, h, and k

(h, k) = (5, 2)

(h, k) = (-4, -9)

good luck, i hope this helps :)

Answer:

One angle is 26 degrees and the other is 64 degrees.

Step-by-step explanation:

Complementary angles add up to a total of 90 degrees. Therefore, if one of the two angles is known to be 38 degrees less, then the other angle can be calculated:

90 = (x-38) + (x)

52 = 2x

26 = x

This means that one of the angles is 26 degrees, and the other is 64 degrees.

I dont have an answer but here is a example I hope it helps

Step-by-step explanation: Josie selected a number n. She divided n by 2 and then subtracted ½ from the result. She took

half of that result and then subtracted ½ to get the final result of 10. What is the value of n?

Let’s start by writing Josie’s first step as an expression. Dividing n by 2, then subtracting ½ from

the result would be (n/2) – ½. If we build on this expression with the information in Josie’s

second step, we get ½((n/2) – ½) – ½. Knowing the final result is 10, we can set up the equation

below, and solve for n as follows:

½((n/2) – ½) – ½ = 10

½(n/2) – ¼ - ½ = 10 (using the distributive property)

¼n – ¼ - ½ = 10 (multiplying to eliminate the parentheses)

¼n – ¾ = 10 (combining like terms)

¼n = 10¾ (adding ¾ to both sides of the equation)

n = 43 (dividing both sides of the equation by ¼)

Answer:

[tex] y = \frac {1}{2}x +2[/tex]

Step-by-step explanation:

Line is passing through the points (0, 2) & (2, 3)

Slope of line = (3 - 2)/(2 - 0) = 1/2

Equation of line in point slope form is given as:

y - 2 = 1/2(x - 0)

2(y - 2) = x

2y - 4 = x

2y = x + 4

[tex] y = \frac {1}{2}x +\frac {4}{2}[/tex]

[tex] y = \frac {1}{2}x +2[/tex]

is the required equation of blue line.

Answer:

2y-4 =x

Rearranged as:

2y = x + 4

x = 2y - 4

y = x/2 +4

Actually Welcome to the Concept of the Volumes.

Volume = base area * Height

hence, here,

base area = 1/2(3)(4)

base area = 6 sq. inches,

now volume = 6 * height

==> Volume = 6*11 = 66 cubic inches

====> hence the volume of the triangular prism is 66 cubic inches.

Given:

Loss percent is 13%.

Selling price = 1475

To find:

The loss or gain if the goods are sold for Rs.1615?

Solution:

Let x be the cost price of goods.

Loss percent is 13% and selling price is 1475.

[tex]1475=x-\dfrac{13}{100}x[/tex]

[tex]1475=x-0.13x[/tex]

[tex]1475=0.87x[/tex]

[tex]\dfrac{1475}{0.87}=x[/tex]

[tex]1695.4023=x[/tex]

[tex]x\approx 1695.40[/tex]

The cost price of goods is 1695.40.

We need to find the loss or gain if the goods are sold for Rs.1615.

Cost price is greater than the selling price because 1695.40 > 1615. It means , it is a loss.

[tex]Loss=CP-SP[/tex]

[tex]Loss=1695.40-1615[/tex]

[tex]Loss=80.40[/tex]

The loss percent is

[tex]Loss\%=\dfrac{Loss}{C.P}\times 100[/tex]

[tex]Loss\%=\dfrac{80.40}{1695.40}\times 100[/tex]

[tex]Loss\%\approx 4.74\%[/tex]

Therefore, the loss is 80.40 and the loss percent is about 4.74%.
