What is the probability that a randomly chosen four-digit integer (no leading zeros) has distinct digits and ends with the digit

S_A_V [24]

Answer:

c. 0.0498

Step-by-step explanation:

First of all, let us find the number of four digit numbers possible.

There are 4 digits and let us have a look at the possibility of each digit.

Number of possible options for Unit's digit = 10

Number of possible options for ten's digit = 10

Number of possible options for hundred's digit = 10

Number of possible options for thousand's digit = 9 (because 0 can not be there to make it a 4 digit number)

Total number of possible outcomes = $10\times 10\times 10\times 9 = \bold{9000}$

As per the given condition, unit's digit is 7.

So, number of possible options for unit's digit = 1

Number of possible options for thousand's digit = 8 (7 and 0 can not be there to make it a 4 digit number)

Number of possible options for hundred's digit = 8 (7 and one digit used in thousand's place can not be there)

Number of possible options for ten's digit = 7 (7, two digits used at thousand's and hundred's places)

Number of possible outcomes as per given conditions = $1\times 8\times 8\times 7 = \bold{448}$

Formula for probability of an event E can be observed as:

$P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}$

$P(E) = \dfrac{448}{9000} =\bold{0.0498}$

Pls. Help me to solve this math problem.

Tju [1.3M]

$\bf (\stackrel{x_1}{x}~,~\stackrel{y_1}{-7})\qquad (\stackrel{x_2}{-6}~,~\stackrel{y_2}{8}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{8-(-7)}{-6-x}=\stackrel{\textit{slope}}{-\cfrac{15}{7}}\implies \cfrac{8+7}{-6-x}=-\cfrac{15}{7} \\\\\\ \cfrac{15}{-6-x}=-\cfrac{15}{7}\implies 105=(-6-x)(-15)\implies 105=90+15x \\\\\\ 15=15x\implies \cfrac{15}{15}=x\implies 1=x$

1. The sides of a triangle are in the ratio 3:4:5 What is the length of each side if the perimeter

Nataly_w [17]

Answer:

22.5 cm, 30 cm, 37.5 cm

Step-by-step explanation:

Sum the parts of the ratio, 3 + 4 + 5 = 12 parts

Divide the perimeter by 12 to find the value of one part of the ratio.

90 cm ÷ 12 = 7.5 cm ← value of 1 part of the ratio, thus

3 parts = 3 × 7.5 cm = 22.5 cm

4 parts = 4 × 7.5 cm = 30 cm

5 parts = 5 × 7.5 cm = 37.5 cm

The 3 sides are 22.5 cm, 30 cm and 37.5 cm
