Answer:

gradient is equal to 0.7

Step-by-step explanation:

line passes on (-2,0) and (0,1.4)

gradient =(y2-y1)/(x2-x1)

=(1.4-0)/-(0--2)

=1.4/2

=1.4/2×10/10

=14/20

=7/10

=0.7

BEST ANSWER GETS BRAINLIEST!! PLEASE HELP

Makovka662 [10]

To find the mean, you add all the elements together, then divide by the number of elements.

Like this:

(45+48+49+40+53)/5=47

in other words the correct answer is 47 inches.

EDIT: Did the foolish mistake, of using the wrong numbers the first time. Fixed now and the answer is correct.

you pick a card at random without getting the first card back you pick a second card at random what is the probability of pickin

Keith_Richards [23]

We have to calculate the probability of picking a 4 and then a 5 without replacement.

We can express this as the product of the probabilities of two events:

• The probability of picking a 4

• The probability of picking a 5, given that a 4 has been retired from the deck.

We have one card in the deck out of fouor cards that is a "4".

Then, the probability of picking a "4" will be:

$P(4)=\frac{1}{4}$

The probability of picking a "5" will be now equal to one card (the number of 5's in the deck) divided by the number of remaining cards (3 cards):

$P(5|4)=\frac{1}{3}$

We then calculate the probabilities of this two events happening in sequence as:

$\begin{gathered} P(4,5)=P(4)\cdot P(5|4) \\ P(4,5)=\frac{1}{4}\cdot\frac{1}{3}=\frac{1}{12} \end{gathered}$
