Answer:
235
Step-by-step explanation:
The population equation is given as P= 2.726x + 126.189
-To find the number of years since 1980, we subtract the start year from the current year(2020):
X=2020-1980=40
We substitute the x value in the population equation to find the current population:
P=2.76x+126.189 but x=40
P=2.76(40)+126.189=235.229
Rounding off then the population in the current year is 235
Answer:
The correct answer is C.
Step-by-step explanation:
The price of a four-star meal, only $50 per couple decades ago, has since increased 400%.
This means that if the $50 per couple is 100%(decimal 1), the current price is 100%+400% = 500%(decimal 5). So we can solve a rule of three to find the current price of a four-star meal.
1 - 50
5 - x
.
The current price of a four star meal is $250 per couple.
The correct answer is C.
Answer:
Step-by-step explanation:
47= 3/44, so ratio is 3/44 for non-nuts muffins
Which mean, for every 44 muffins we would have 3 non-nuts muffins.
Given the function h(x)=x^2+14x+41, to solve by completing square we procced as follows;
x^2+14x+41=0
x^2+14x=-41
but;
c=(b/2)^2
and b=14
hence;
c=(14/2)^2=49
substituting the value of c in the expression we get:
x^2+14x+49=-41+49
x^2+14x+49=8
(x+7)^2=8
this can be written in vertex form;
h(x)=a(x-h)^2+k
where:
(h,k) is the vertex;
thus
(x+7)^2=8
h(x)=(x+7)^2-8
hence the vertex will be at the point:
(-7,-8)
Answer:
A number that measures the likelihood that the event will occur.
Step-by-step explanation:
Probability is a measure of the frequency of occurrence of a phenomenon, the value of which can be expressed qualitatively or quantitatively. Probability is quantified as a real number between 0 and 1, although sometimes probability is also expressed as a percentage. The probability is 0 when the event cannot or will never happen, and the probability is 1 when it happens for sure or it always happens. If the probability is between these values, the event is not common and its occurrence is uncertain. The higher the probability value, the more common the event is or the more certain it will occur.
