Answer:

Sorry if I saw this late.

Step-by-step explanation:

Whenever dividing fraction, ALWAYS flip the number with the division sign in front of it. After number is flipped, multiply both numbers.

We will do:

3 x 2/1= 3x2=6

d1i1m1o1n [39]

Answer:

$-2$

Step-by-step explanation:

$\frac{\log _{10}\left(\frac{1}{36}\right)}{\log _{10}\left(6\right)}$

$\log _6\left(\frac{1}{36}\right)$

$-\log _6\left(36\right)$

$-\log _6\left(6^2\right)$

$-2\log _6\left(6\right)$

$-2\cdot \:1$

$-2$

There are five boys and five girls in a class. The teacher randomly selects three different students to answer questions. The fi

Damm [24]

The probability that the first student is a girl is 5/10.

The probability of the second selection being a boy is 5/9.

(since the first selection was a girl, there are 9 students left)

The probability that the third student is a girl is 4/8

(there are 4 girls left after one was selected, and 8 students left in total, after the second selection.

The probability is (5/10)(5/9)(4/8)=0.139

Answer: 0.139

Answer:

The estimated mean number of rockets hits in the region is 533.

Step-by-step explanation:

We are given the following information,

Number of rocket hits | Observed number of regions

0 | 228

1 | 214

2 | 94

3 | 32

4 | 7

5 | 0

6 | 0

7 | 1

We are asked to estimate the mean number of rocket hits in the region.

The mean or expected value is given by

$\mu = \sum (x \cdot P(x)) \\\\\mu = (0 \cdot 228) + (1 \cdot 214) + (2 \cdot 94) + (3 \cdot 32) + (4 \cdot 7) + (5 \cdot 0) + (6 \cdot 0) + (7 \cdot 1) \\\\\mu = 0 + 214 +188+ 96 +28 +0+ 0 + 7 \\\\\mu = 533$

Therefore, the mean number of rockets hits in the region is 533.

Write the equation of the line in fully simplified slope-intercept form.

hoa [83]

Answer:

y = -x+3

Step-by-step explanation:

Slope intercept form => y = mx+b

To find 'm', the slope, pick 2 coordinates.

(0,3)

(2,1)

Use this equation to find the slope using these 2 coordinates: (y1 - y2)/(x1 - x2)

(3 - 1)/(0 - 2) = -1

m = slope = -1

'b' is the y-intersept, or the point when a line passes through the y-axis. That's (0,3).

b = y-intercept = 3

<em>So the equation will be y = -1x + 3, or y = -x + 3</em>

Write a description of how a diagram can help you solve 2×40

nasty-shy [4]

Let me explain like this .Suppose There are 40 people gathered somewhere for attending an event.Each Person has to be given 2 sweets for their arrival or for showing their presence in the event. Now 40 other woman joined them..Instead of getting two sweets each of them got one sweet.

Solution: 2 sweets × 40 people = 1 sweet × 80 people = 80

2nd Way:

There are 40 rooms in a building.In Each room we have to fix two bulbs. So How many bulbs are there in the building.

Solution →→→2 bulbs × 40 room = 80 bulbs

Diagram is depicted below for two parts.
