Just remember BODMAS, which B= brackets O= Order D= Division M= Multiply A=Addition and S=Subtract
So first you solve the brackets so 44+22 is 66
So 66-4+12 so 66-4 is 62
62+12 is 74
So now you have got 74 divided by 2 which is 37
Hope this helps xx
When x=1 and -2 so it is C
An isotherm on a geographic map is a type of
equal temperature at a given date or time. And if we talk about thermodynamics,
it is a curve on a Pressure – Volume diagram at a constant temperature.
Basing from the graph, we can actually see that
the interval is:
10 <span>Fahrenheit degrees</span>
Break into 2 equatins to get x's:
2x-6<4 and 2x-6>-4
Solve for x in both:
2x-6<4
2x<10
x<5
2x-6>-4
2x>2
x>1
Graph both inequalities on the same number line:
<---0-----1-----2-----3-----4-----5-----6--->
Answer:
Step-by-step explanation:
Given that a survey showed that 72% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight
X - number of people who need correction for their eyesight
X is binomial since each event is independent and there are only two outcmes.
X (18, 0.72)
Required probability = the probability that no more than 1 of them need correction for their eyesight.
=P(X=0)+P(X=1)=0.00000296+0.000137
=0.00014
Yes 1 is a significantly low number as probability is almost zero.
