HELP ME PLEASE ASAP!!!!!: Stock worth $60 a share dropped in value by 20% on Monday. Then, it dropped again by $10 the next Tues
vredina [299]

Answer:

$58.9

Step-by-step explanation:

In this question, we're going to go step by step to get the final price of the share.

We know that the stock started off as $60 per share, so that would be our starting value.

The stock dropped by 20%, so let's calculate the drop in price.

60 • 0.20 = 12

60 - 12 = 48

On Monday, the value of the stock was $48

On Tuesday, the stock dropped by $10, so calculate that drop as well

48 - 10 = 38

On Tuesday, the stock value is at $38

The stock increased by 55%, so we need to calculate the increase.

38 • 1.55 = 58.9

This means that the final price of the share was $58.9

I have to turn this in tonight please help :(
Leni [432]

Answer:

angle a is 116 degrees

Step-by-step explanation:

ok so first we have to make everything equal to 180 because every triangle is 180 degrees so it would be written like this:

(14x + 4) + (5x - 1) + (2x + 9) = 180

Then, we solve for x and x equals 8

After this we plug 8 back into the angle so it would be written like this:

14(8) + 4

This equals 116 degrees.

The following random sample was selected from a normal distribution: 4.5, 6.4, 2.3, 1.8, 5.3, then the 95% confidence interval t
kap26 [50]

Answer:

the 95% confidence interval to estimate the population mean is between  1.62 and 6.50

Step-by-step explanation:

given data

distribution = 4.5, 6.4, 2.3, 1.8, 5.3

so n = 5

confidence interval = 95%

to find out

the population mean is between

solution

first we calculate the mean i.e.

mean =  \frac{1}{n}\sum_{i=1}^{n}x(i)

mean =  4.5+ 6.4+ 2.3+ 1.8+ 5.3 / 5

mean = 4.06

now we calculate the standard deviation i.e.

standard deviation =   \sqrt{\frac{1}{n-1}\sum (x(i)-mean)^2}

standard deviation =   \sqrt{\frac{1}{5-1}\sum (x(i)-mean)^2}

standard deviation =   \sqrt{\frac{1}{5-1} (4.5-5)^2+(6.4-5)^2 +(2.3-5)^2+(1.8-5)^2+(5.3-5)^2}

standard deviation =   \sqrt{\frac{1}{4} (4.5-5)^2+(6.4-5)^2 +(2.3-5)^2+(1.8-5)^2+(5.3-5)^2}

standard deviation =  2.226544

so 95 % confidence interval is i.e. mean +/- t(5) * standard deviation/ \sqrt{n}

here t(5) will be 2.45

so

95 % confidence interval=  4.06 +/- 2.45 * 2.226 / \sqrt{5}

95 % confidence interval= 1.62 and 6.50

When you multiply my number by 6 and add 7 you get 25 what is my number
pav-90 [236]
To solve this you do 25-7=18 and do 18÷6=3, so my number is 3. To check if this is correct you do 3×6=18 and 18+7=25
