Answer:

Step-by-step explanation:

You have a 1 in 6 chance to roll a two. This means that every six times you roll a dice 1 of those should be a two (Obviously in the real world this wouldn't happen)

You roll the dice 18 TIMES and your chances are 1 in 6 so you take

$18 \times \frac{1}{6}$

Answer:

lower limit : 36.44

upper limit : 39.56

Step-by-step explanation:

Given :

s = 9

n = 90

x = 38.9

Alpha, α = 0.10

∴ $z_{\alpha/2}=z_{0.05} = 1.645$

The confidence interval is :

$=x \pm\left(z_{\alpha /2} \times \frac{s}{\sqrt{n}}\right)$

$=38.9 \pm\left(1.645 \times \frac{9}{\sqrt{90}}\right)$

$=38.9 \pm 1.56$

$=(36.44, 39.56)$

Therefore,

lower limit : 36.44

upper limit : 39.56

WILL GIVE EXTRA POINTS assignment name: transformations

a_sh-v [17]

Answer:

K(1,0), L(2, 3), M(-1, 4), N(-2,1)

Step-by-step explanation:

Because the points are being flipped over the x-axis the y values remain the same, but the x values are multiplied by -1. Multiplying the values by -1 will switch a negative value positive and a positive value negative. This will correctly flip the points to the opposite side of the graph.

What are some key words used to note addition operations?

djverab [1.8K]

Answer:

The correct answer is

For addition, Caulleen used the words total, sum, altogether, and increase. But we could also have used the words combine, plus, more than, or even just the word "and". For subtraction, Caulleen used the words, fewer than, decrease, take away, and subtract. We also could have used less than, minus, and difference.
