Answer:
4.2
Step-by-step explanation:
simplify 12 and 20 to 6 and 10 then divide 6 by 10 and multiply by 7 to get the answer.
Place value. when multiplying by 10 you are moving a decimal, having everything lined up like place value would save you a lot of time.
Sum means to Add.
So the sum of d and 9 would be d + 9
Answer: X = 44.4 degrees
Step-by-step explanation: The figure given is a right angled triangle with two sides given as well as one angle unknown.
Angle X, which is the unknown, is the reference angle in this question. So we have an opposite which is the side facing the reference angle (line 7 units) and we have an hypotenuse which is the side facing the right angle (line 10). Having an opposite and an hypotenuse, we can use the trigonometric ratio of sine.
SinX = opposite/hypotenuse
SinX = 7/10
SinX = 0.7000
Looking up a table of values or checking the calculator, 0.7000 under sine of angles gives 44.4270
Therefore angle X is approximately 44.4 degrees (approximated to the nearest tenth)
Answer:
d) The data are quantitative because they consist of counts or measurements.
Step-by-step explanation:
The number of cases of flu treated at a certain hospital in different years consists in integer numbers (there cannot be 108.4 cases of flu treated in one year, just 107, 108, 109, etc).
Therefore the date are quantitative because the data consists of numbers which are counts of a certain number of individuals who were affected by the flu during different years.
