What is the estimate for square root of 22
tigry1 [53]
<span>16=4²
25=5² 
</span>So that means the square root of 22 is between 4 and 5.
Square 4.5 
4.5² = 20.25 
<span>4.5 < √22 < 5
So the nearest whole number would be 5.

Please help with 6 and 7
Maru [420]

Answer:

6a) i- 2hrs 36mins  ii- 3hrs 12mins

b) car A≈ 76.9km/h  car B≈ 62.5km/h

c)------

7a) 35km

b) car A=75km  car B=60km

c) 30km

d) car A≈36mins  car B≈48mins

Step-by-step explanation:

6a) Using the graph follow the lines until they finish then go downwards until you get to the x-axis. The x-axis is going up by 12mins for each square.

b) Using the answer from a, you divide 200km by the time.

For car A 2hrs 36mins becomes 2.6 because 36mins/60mins=0.6

∴ car A: 200/2.6≈ 76.92km/h

For car B 3hrs 12mins becomes 3.2 because 12mins/60mins=0.2

∴ car B: 200/3.2≈ 62.5km/h

7a) Using the graph go down from where the line of car A finished to meet car B. The y-axis is going up by 5km for each square.

b) Starting from the x-axis at 1 hour go upwards to see where you meet the car B line (60km) and car A line(75km). (sorry if that does not really make sense).

c) Difference from car A line to car B:

155km-125km=30km

d) Going across from 50km meet car A line and go down to see it has been travelling for approx. 36mins. Then continue across to car B line, go down to see it reached 50km at approx. 48mins.

Hope this helps.

Answer Choices : (A) 1/6 (B)5/36 (C) 1/2 (D) 1/36
Sati [7]

Answer:

Probability = \frac{1}{6}

Step-by-step explanation:

Given

The above table

Required

Determine the probability of a sum that is a multiple of 6

Represent the event that an outcome is a multiple of 6 with M.

List out all possible values of M

M = \{6,6,6,6,6,12\}

Number of M is

n(M) = 6

Total possible outcome is:

n(Total) = 36

The theoretical probability is then calculated as follows:

Probability = \frac{Number\ of\ desired\ outcomes}{Number\ of\ possible\ outcomes}

In this case, it is:

Probability = \frac{n(M)}{n(Total)}

Probability = \frac{6}{36}

Simplify fraction

Probability = \frac{1}{6}
