The distance between points (1, 1) and (4, 7) is 6.71. is it true or false

1 answer:

3 0

To determine whether the statement is true or false, we need to calculate for the distance of the two points. To do this, we can use the pythagorean theorem as follows:

d = √[(y2-y1)^2 + (x2-x1)^2]
d = √[(7-1)^2 + (4-1)^2]
d = √[(6)^2 + (3)^2]
d = 2√13 = 7.21

Therefore, the statement is false.

Only blue and white vans are made at a factory. The ratio of the number of blue vans to the number of white vans is 4 : 3 write

amid [387]

Answer:

4/7

Step-by-step explanation:

Number of Blue vans = 4

Number of white vans = 3

Total number of vans = Number of Blue vans + Number of white vans

= 4 + 3

= 7 vans

Number of blue vans : Number of white vans = 4 : 3

Fraction of vans that are blue = Number of Blue vans / Total number of vans

= 4 / 7

Fraction of vans that are blue = 4/7

You pick a card at random. Without putting the first card back, you

Inga [223]

First, we need the probability of picking an odd number.

There are 5 cards in total, and 3 odd cards (3, 5, and 7).

That means that the probability that we'll draw an odd card would be $\frac{3}{5}$ .

Then, we have 4 cards left, and 2 even cards (4 and 6), meaning that the probability that we draw an even card will be $\frac{2}{4}$ or $\frac{1}{2}$ .
