What is 45/60 in simplest form

1 answer:

8 0

We are asked in the problem to determine the simplest form of the number 45/60. The greatest common factor of the two numbers is 15. Hence, we divide each number by 15, that is 45 over 15 is equal to 3 and 60 over 15 is equal to 4. Hence the answer is 3/4.

Compared to others, which one of the following is not robust to outliers? a) Mean b) Median c) Mode d) 50th percentile

tatyana61 [14]

Answer:

The mean.

Step-by-step explanation:

The mean is not robust.

The presence of an outlier greatly affects the value of a mean.

An example will illustrate this.

Find the mean of the numbers 2 3 5 6 34.

34 is an outlier. The mean = (2+3+5+6+34) / 5 = 10.

Now if we replace the outlier with a number closer to the others:

Say we have 2 3 5 6 8 :

The mean = (2+3+5+6+8) / 5 = 4.8 which is a much truer measure of centrality than 10.

In ΔFGH, the measure of ∠H=90°, HG = 33, GF = 65, and FH = 56. What ratio represents the cosecant of ∠F?

Pachacha [2.7K]

Answer:

$Cosec\ F= 1.9697$

Step-by-step explanation:

Given

$\angle H=90^\circ$

$HG = 33;\ GF = 65;\ FH = 56.$

Required

The cosecant of F

See attachment for triangle illustration

Cosecant is calculated as:

$Cosec\theta = \frac{Hypotenuse}{Opposite}$

So,

$Cosec\ F= \frac{GF}{HG}$

So, we have:

$Cosec\ F= \frac{65}{33}$

$Cosec\ F= 1.9697$

Answer:

Step-by-step explanation:

Consider a group of 50 people whose blood groups are given below:

A, B, A, B, AB, AB, O, O, O, AB, O, A, A, B, O, A, A, A, B, AB, B, A, AB, O, B, A, A, A, AB, AB, AB, O, B, O, A, O, A, B, B, O, A, AB, A, B, AB, B, A, AB, A, B

To present the above information, we need a frequency table.

Blood group Frequency

A 17

B 12

AB 11

O 10

Amanda, Sarah and Bethany share the cost of a holiday in the ratio 5 : 4 : 3.

sp2606 [1]

Answer:

a. £564

b. £141

Step-by-step explanation:

a. Firstly, we add up the ratios

= 5 + 4 + 3 = 12

Amanda’s share was 5

Let the total amount be £x

Thus; 5/12 * x = 235

5x = 12 * 235

x = 2820/5 = 564

The total cost of the holiday is £564

b. We want to calculate what Bethany paid

That would be 3/12 * 564 = £141
