Answer:
Part a)
Part b) 132:89 vs 132 to 89
Part c)
Part d) 66:7 vs 66 to 7
Step-by-step explanation:
Let
x ----> the number of boys
y ----> the number girls
z ----> the number of adults
we have
x=132, y=89, z=14
Part a) Write the ratio of the number of boys to the number of girls.
To find the ratio of the number of boys to the number of girls, divide the number of boys by the number of girls
so
substitute
Part b) Write the same ratio using another form (A: B vs. A to B)
we have
The other form is
132:89 vs 132 to 89
Part c) Write the ratio of the number of boys to the number of adults
To find the ratio of the number of boys to the number of adults, divide the number of boys by the number of adults
so
substitute
Simplify
Part d) Write the same ratio using another form
The other form is
66:7 vs 66 to 7
Curve it to get the answe than radical it to get the second number
Answer:
m<RPQ = 22°
Step-by-step explanation:
Given:
m<SRQ = 90°
PS = PQ
m<SQR = 46°
Required:
m<RPQ
Solution:
m<SQR + m<SRQ + m<RSQ = 180°
Substitute
46° + 90° + m<RSQ = 180°
m<RSQ = 180° - 136°
m<RSQ = 44°
Find m<PSQ:
m<PSQ = 180° - m<RSQ (Angles on a straight line
m<PSQ = 180° - 44° (Substitution)
m<PSQ = 136°
Find m<RPQ:
∆QSP is an isosceles triangle with two equal base angles. Therefore:
m<RPQ = ½(180° - 136°)
m<RPQ = 22°
What is the question for the problem are you trying to figure out area or perhaps perimeter and of what the shaded or non shaded next time include that in your answer.
Answer:
Step-by-step explanation:
Total voters = 900
Republicians =369
Democrats =468
Independents = 63
Sample size n =90
a) The expected value of the number of Republicans in the sample is
=
b) The chance the sample contains only Republicans and Democrats is
= (no of republicians+democrats)/total people
=
c)
