P = $1400,300 r = 7 1/2% t = 4 what is i ? $4.29 $429.00 $4290.00

bazaltina [42]

Answer:

Interest is $420090 .

Step-by-step explanation:

Formula

$Simple\ interest = \frac{Principle\times Rate\times Time}{100}$

As given

P = $1400,300

t = 4

$r = 7 \frac{1}{2}\%$

$r = \frac{15}{2}\%$

r = 7.5 %

Putting all the values in the formula

$Simple\ interest = \frac{1400300\times 7.5\times 4}{100}$

$Simple\ interest = \frac{4200900}{100}$

Simple interest = $ 420090

Therefore the interest is $420090 .

A right triangle has a vertex at point M and a height of 5 units. The base of the triangle is on MN←→− and is 3 units long. One

Julli [10]

Answer:

We are given a triangle having vertex at point M.

The base of the triangle is MN which is 3 units long.

Now, the height of the triangle is given as 5 units.

So, plotting a line starting at M, which is 5 units long towards the left or right will give us the height of the triangle.

Moreover, as the base is 3 units long.

We will have that the point N is 3 units down or up from the point M.

Using Pythagoras theorem, get that the length of the third side is 5.8 units.

After joining these points and constructing straight lines, we will get the following right angles triangle having base 3 units and height 5 units.

A major department store has determined that its customers charge an average of $500 per month, with a standard deviation of $80

julia-pushkina [17]

Answer:

Step-by-step explanation:

Since the amounts of charges are assumed to be normally distributed,

we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = the amounts of charges.

µ = mean amount

σ = standard deviation

From the information given,

µ = $500

σ = $80

a) the probability that customers charges more than $380 per month is expressed as

P(x > 380) = 1 - P(x ≤ 380)

For x = 380,

z = (380 - 500)/80 = - 1.5

Looking at the normal distribution table, the probability corresponding to the z score is 0.067

P(x > 380) = 1 - 0.067 = 0.933

The percentage of customers that charges more than $380 per month is

0.933 × 100 = 93.3%

b) the probability that customers charges less than $340 per month is expressed as

P(x < 340)

For x = 340,

z = (340 - 500)/80 = - 2

Looking at the normal distribution table, the probability corresponding to the z score is 0.023

The percentage of customers that charges less than $340 per month is

0.023 × 100 = 2.3%

c) the probability that customers charges between $644 and $700 per month is expressed as

P(644 ≤ x ≤ 700)

For x = 644,

z = (644 - 500)/80 = 1.8

Looking at the normal distribution table, the probability corresponding to the z score is 0.96

For x = 700,

z = (700 - 500)/80 = 2.5

Looking at the normal distribution table, the probability corresponding to the z score is 0.994

P(644 ≤ x ≤ 700) = 0.994 - 0.96 = 0.034

The percentage of customers that charges between $644 and $700 per month is

0.034 × 100 = 3.4%
