Answer:

The number line goes from negative two to two.

The numbers shown by the number line (-2, -1, 0, 1 and 2) are all integers.

Between each pair of numbers, there are 4 equal segments, each one of 1/4 = 0.25 units length. Therefore we can locate, for example, 1.25, 0.5 and -0.75 at the number line.

The number line is divided into fourths.

Zero is at the center of the number line.

Numbers get larger as you move to the right on the number line.

Numbers get smaller as you move to the left on the number line.

Tom has some marbles in two bags. In one bag he has 3 yellow, 2 green and 1 red marble. In the other bag he has 3 yellow, 3 gree

shutvik [7]

Answer:

1 / 3

Step-by-step explanation:

Bag 1 :

Yellow = 3

Green = 2

Red = 1

Total = 3 + 2 +1 = 6

Bag 2 :

Yellow = 3

Green = 3

Red = 3

Total = 3 + 3 + 3 = 9

P(not yellow from bag 1) = (green + red) / total = 3 /6 = 1/2

P(not yellow from bag 2) = (green + red) / total = 6/9 = 2 /3

P(neither is yellow) = 1/2 * 2/3 = 2 / 6 = 1/3

Bob Nale is the owner of Nale's Quick Fill. Bob would like to estimate the mean number of gallons of gasoline sold to his custom

Mnenie [13.5K]

<h2>Answer with explanation:</h2>

As per given , we have

$\ovreline{x}=8.17$

$\sigma=2.2$

n= 64

a) Since , the sample mean is the point estimate for the population mean.

Therefore, the point estimate of the population mean = $\ovreline{x}=8.17$

b) Critical z-value for 99% confidence : $z_{\alpha/2}=2.576$

Confidence interval :

$\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}$

$8.17\pm (2.576)\dfrac{2.2}{\sqrt{64}}$

$8.17\pm 0.7084$

$(8.17-0.7084,\ 8.17+0.7084)=(7.4616,\ 8.8784)\approx (7.46,\ 8.88)$

Hence, the 99 percent confidence interval for the population mean is between 7.46 and 8.88.

The quotient of a number and -5 has a result of 2. What is the number?

balu736 [363]

Answer:

<h3>The number is - 10</h3>

Step-by-step explanation:

quotient of a number and -5 is written as

$\frac{x}{ - 5}$

Equate it to 2

We have

$\frac{x}{ - 5} = 2$

Cross multiply

That's

x = 2 × - 5

x = - 10

Hope this helps you

Does anyone have the solution to this

klasskru [66]

Step-by-step explanation:

There is 1 root at x = 1, where the function crosses the x-axis.

There are 2 roots at x = -2, where the function touches the x-axis but does not cross.

So there are 3 real roots total.

The function is:

y = (x − 1) (x − (-2))²

y = (x − 1) (x + 2)²
