Answer:
There are 80 men on the train.
Step-by-step explanation:
M : W
4 : 5
W : C
10 : 9
As you can see, the units for women is not equal, so I shall multiply the first ratio by 2 so that the units for women is 10.
M : W
8 : 10
Now that everything has the same units, I can put the ratio of men, women and children together:
M : W : C
8 : 10 : 9
Total number of units = 8 + 10 + 9
= 27
27 units = 270
No. of men (8 units) = \(\frac{8}{27}\) × 270
= 80
A media personality argues that global temperatures are not rising because every year an increase is reported such as 0.09 degrees Celsius. The difference from the previous year is less than the margin of error of about 0.13 degrees C, so that difference should be ignored. What is the best counterargument?
Answers
The media personality's argument is flawed because they are basing their conclusion on a single year's data and ignoring the overall trend of increasing global temperatures. To counter this argument, one can make the following points:
1. While it is true that the annual increase in temperature may be less than the margin of error, the trend of increasing temperatures over several decades cannot be ignored. The margin of error is a statistical concept that takes into account the uncertainty in the measurement, but it does not negate the overall trend.
2. Global temperature records show that the Earth's temperature has been steadily rising over the past century, with the 10 warmest years on record occurring since 2005. This trend cannot be explained by natural variability alone and is consistent with the effects of human-caused climate change.
3. The consequences of rising global temperatures, such as melting glaciers, rising sea levels, and more frequent extreme weather events, are already being felt around the world. Ignoring this trend could have devastating consequences for future generations.
In summary, the media personality's argument is based on a flawed understanding of statistics and ignores the overall trend of increasing global temperatures. The best counterargument is to highlight the overwhelming evidence of climate change and its potential consequences.
Let's roll two dice and find the probability of rolling a certain sum. Is this a simple or compound event?
Two dice - Red and Blue
Recall that a simple event has one and only one outcome of interest. In this example, we are rolling two dice, but we are only interested in one outcome, the sum of the two dice. This is a simple event.
What is the probability of:
Rolling a sum of 1?
Rolling a sum of 3?
Rolling a sum of 12?
Rolling a sum of 7?
Since we are rolling a pair of dice and looking for the sum, the sample space is a little more complicated than rolling one die. The chart below will help us determine the possible outcomes. The top row indicates the numbers on the sides of the blue die and the first column represents the number on the sides of the red die. The white area indicates the sum of the numbers in the row and column.

Factorise fully 6x+8
Answers
Answer: To factorize the expression 6x + 8 fully, we can first look for the greatest common factor (GCF) of the two terms. In this case, the GCF is 2.
Step 1: Factor out the GCF:
2(3x + 4)
Now, we have the expression 3x + 4 inside parentheses. This expression cannot be further factorized since there are no common factors other than 1.
Therefore, the fully factorized form of 6x + 8 is:
2(3x + 4)
Step-by-step explanation:)
The factored expression is:
↬ 2(3x + 4)Step-by-step explanation:
To factor the expression, look at its GCF (greatest common factor).
Clearly the GCF of both terms is 2. So what we do next is we divide both terms by 2 :
6x ÷ 2 + 8 ÷ 2The result is :
3x + 4And now the 2 goes outside the parenthesis:
2(3x + 4)Hence, the answer is 2(3x + 4).

Answers
This function represents a downward-opening parabola with a vertical shift of 6 units upward.
How to explain the functionThe given function is Ƒ(t) = –1/(2t²) + 2t + 6.
This is a quadratic function in terms of t. The general form of a quadratic function is f(t) = at² + bt + c, where a, b, and c are constants.
Comparing the given function Ƒ(t) = –1/(2t²) + 2t + 6 with the general form, we can see that a = -1/2, b = 2, and c = 6.
So, the function Ƒ(t) can be written as:
Ƒ(t) = (-1/2)t² + 2t + 6
This function represents a downward-opening parabola with a vertical shift of 6 units upward.

The number of days which it would take 1000 people to sign the petition as required in the task content is; 4.35 days.
What is the number of days required for 1000 people to sign the petition?It follows from the task content that the number of days which it would take Jan to get 1000 signatures on the petition be determined.
Since it is given in the task content that 230 people sign the petition each day.
It therefore follows from proportion that the number of days needed for 1000 people to sign the petition is;
= 1000/230
= 4.3478 days.
Hence, the number of days which it would take 1000 people to sign the petition is approximately; 4.35 days.

The total surface area and the curved surface area of cone are 704 sq. cm. and 550 sq. cm. respectively. Find the slant height of the cone. 20
Answers
l ≈ 17.72 cm
Step-by-step explanation:
Let's denote the slant height of the cone as "l" and the radius of the cone as "r".
We know that the total surface area of the cone is given by:
πrl + πr^2
And we also know that the curved surface area of the cone is given by:
πrl
So we can write two equations using these formulas:
πrl + πr^2 = 704 (1)
πrl = 550 (2)
Now, we can solve for "l" by substituting equation (2) into equation (1):
550 + πr^2 = 704
πr^2 = 154
r^2 = 154/π
r ≈ 6.223 cm
Substituting this value of "r" into equation (2), we get:
πl(6.223) = 550
l ≈ 17.72 cm
Therefore, the slant height of the cone is approximately 17.72 cm.
