Step-by-step explanation:

Let the ages of son and daughter be 5x and 4x Then

By the question

The age of a man is equal to the sum of the ages of his son and daughter . So

5x + 4x = 9x

Now

it is given that

age of the man = 45

or 9x = 45

x = 45 / 9

x = 5

Finally

Age of son = 5x = 5 * 5 = 25

Age of daughter = 4x = 4 * 5 = 20

Hope it will help :)❤

Please help!!!!!!!!!!!!!!!

babunello [35]

Answer:

Answer A

Step-by-step explanation:

Answer A indicates some minimal value for the set of points to the left (negative side of the distribution) which are associated with negative skewness since the mean is at 22 also with larger deviation to the left shown in the median of the points to the left further to the negative side of the plot.

Answers B and C show symmetric distributions (no skewness at all).

Answer D would represent skewness to the right (positively skewed)

So the correct answer is answer A.

Answer:

The equation should be h²=P²+b²

27²=15²+18²

729=225+324

729=549

suppose you deposit $2,475 in a savings account that earns 6.25% simple interest per year. How much simple interest would be ear

Nikolay [14]

$116.02 interest will be earned in 9 months

Step-by-step explanation:

The formula for simple interest is given by:

$I = Prt$

Here

P is the initial amount

r is the interest

t is the time measured in years

Given

P = $2475

r = 6.25% = $\frac{6.25}{100} = 0.0625$

t = 9 months

Converting time into year by dividing by 12

$t = \frac{9}{12}\ years = 0.75\ year$

Putting the values in the formula

$I = 2475 * 0.0625 * 0.75\\I = 116.0156$

Rounding off to nearest hundredth

I = $116.02

Hence,

$116.02 interest will be earned in 9 months
