Question 3 of 10

Mathematics
1 answer:
Bas_tet [7]3 years ago
4 0

Answer:

A. y-5=1.5(x-4).

B. y=1.5x-1.

Step-by-step explanation:

The given line passes through (2,2) and (4,5).

The slope the given line can be found using the formula;

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{5-2}{4-2}

This gives m=\frac{3}{2}=1.5.

The slope-intercept form is y-y_1=m(x-x_1).

We substitute the second point to get:

y-5=1.5(x-4).

We expand to get:

y-5=1.5x-6.

y=1.5x-6+5.

y=1.5x-1.

vlabodo [156]

Answer: The perimeter is 48 inches. The area is 140

Step-by-step explanation:

Since we have the length and width, we know the formula of perimeter is L+L+W+W. So 10+10+14+14= 48 The formula of area is LxW so 14 x 10= 140

a card is chosen from a standard deck, then a month of the year is chosen. find the probability of getting a face card and june​
Irina-Kira [14]

Answer:

Probability of chossing a face card and the month of june = 0.019

Step-by-step explanation:

Let A be the event that a face card is chosen from a deck of 52 cards

And

B be the event that a month is being chosen from 12 months of an year

So,

n(S)for A=52

n(S)for B=12

As a deck of card has total of 12 face cards so

P(A)=12/52

=3/13

P(B)=1/12

As both the events are independent, the probability of A and B is the product of both events’ probabilities.

P(A and B)= P(A)*P(B)

=3/13*1/12

=3/156

=0.019
