Answer:

3/4

Step-by-step explanation:

You can see that there are 4 cards with numbers 5, 6, 7 and 8 on them. They make the sample space. Total outcomes, n(S) = 4

Let the event E is picking a card not less than 6.

The outcomes of the event 'not less than 6' are 6, 7 and 8. So n(E) = 3

So, the required probability, P(not less than 6) = n(E) / n(S) = 3/4

Answer:

3/4

Step-by-step explanation:

There are 4 cards total

The card not less than 6 are 6,7,8 = 3 cards

P( not less than 6) = number of cards not less than 6 / total

                              = 3/4

9x-8(x-6)=52 what is the answer
Effectus [21]

Answer:

x = 4

Step-by-step explanation:

Step 1: Write equation

9x - 8(x - 6) = 52

Step 2: Solve for <em>x</em>

  1. Distribute -8: 9x - 8x + 48 = 52
  2. Combine like terms: x + 48 = 52
  3. Subtract 48 on both sides: x = 4

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

9(4) - 8(4 - 6) = 52

36 - 8(-2) = 52

36 + 16 = 52

52 = 52

the area of a rectangle is 95 square yard. if the perimeter is 48 yards find the length and width of rectangle
Vladimir [108]
Try this option:
according to the condition w+l=48 and w*l=95.
Using these two equation:
\left \{ {{l+w=48} \atop {lw=95}} \right. \ =\ \textgreater \  \   \left[\begin{array}{ccc}l=24- \sqrt{481};w=24+ \sqrt{481}\\ \\l=24+ \sqrt{481};w=24- \sqrt{481}\end{array}

6.- Find the area under the standard normal distribution: to the left of z=-1.55.
Kisachek [45]

Answer:

P(z

Step-by-step explanation:

For this case we want to find this probability:

P(z

Because they want the area to the left of the value. We need to remember that the normal standard distribution have a mean of 0 and a deviation of 1.

We can use the following excel code: =NORM.DIST(-1.55,0,1,TRUE)

And we got:

P(z

The other possibility is use the normal standard table and we got a similar result.
