find the sum of the first 50 terms below. an=3n+2
Step-by-step explanation:
1st term = a(1) = 3(1) + 2 = 5
50th term = a(50) = 3(50) + 2 = 152
Sum of first 50 terms = (5 + 152) * (50/2) = 3925.

In the first week of July, a record 1,060 people went to the local swimming pool. In the second week, 100 fewer people went to the pool than in the first week. In the third week, 140 more people went to the pool than in the second week. In the fourth week,146 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four weeks?
Answer: 10%
Step-by-step explanation:
As per given ,
Initial number of people went to pool = 1060
After 4 weeks periods, number of people went to pool = 1060 - 100 +140 -146 ['+' for addition . '-' for decrease]
= 954
The percent decrease in the number of people who went to the pool over these four weeks = [tex]\dfrac{1060-954}{1060}\times 100[/tex]
[tex]=\dfrac{106}{1060}\times100\\\\=10\%[/tex]
Hence, the percent decrease in the number of people who went to the pool over these four weeks = 10%

Please Mark As Brainliest!!
834 and 799
Step-by-step explanation:
x+y=1633
x-y=35
2x= 1668
x=834
y=799
Answer:
((819.458,813.542)
Step-by-step explanation:
sum of two numbers=1633
x+y=1633----equation (i)
their difference=35
(x-y)^2=35----equation (ii)
solve simultaneous equation by using substitution method
x+y=1633
make x the subject of the formula
x=1633-y---(i)
substitute equation (i)into (ii)
(x-y)^2=3
(1633-y-y)^2=35
(1633-2y)^2=35
apply square root both sides
√(1633-2y)^2=√35
1633-2y=√35
-2y=√35-1633
-2y=-1627.08392
divide both sides by -2
y=813.5419601
substitute the value of y in equation (i
x=1633-y
x=1633-813.5419601
x=819.4580399
therefore the two numbers are (819.458, 813.542)

By remote interior angle property if a triangle, we have:
19x° + (18x - 4)° = 144°
(18x - 4 + 19x)° = 144°
(37x - 4)° = 144°
37x - 4 = 144
37x = 144 + 4
37x = 148
x = 148/37
x = 4

What is the length of DC?
O 2 units
O 3uníts
O 6uníts
O 9 unit
Answer:
The correct option is;
3 units
Step-by-step explanation:
From the given figure, we have that segment DE is parallel to segment CB of triangle ABC
According to triangle proportionality theorem we have that segment DE which is parallel to segment CB of triangle ABC, divides the other two sides the triangle ABC proportionally
We have;
[tex]\overline {DC}[/tex]/[tex]\overline {AD}[/tex]= [tex]\overline {EB}[/tex]/[tex]\overline {AE}[/tex]
[tex]\overline {DC}[/tex]/9 = 4/12
[tex]\overline {DC}[/tex]= 9 × 4/12 = 3
[tex]\overline {DC}[/tex]= 3 units
The length of the segment DC = 3 units.

50% people use cellular mobile and 40% people use landline and 20% people use both. Find the probability that a person selected at random use neither.
a) 10% b) 30%
c) 70% d) 90%
Answer:
a) 10%
Step-by-step explanation:
To be able to own both (20%), you must fall into both categories. You own a cellular mobile, and you own a landline. The 20% is within the 50% + 40%.
50% + 40% = 90%
Subtract 90% from the total amount:
100 - 90 = 10
A) 10% is your answer.

Is the discriminant of g positive, zero, or negative?
Answer:
The discriminant can be positive, zero, or negative, and this determines how many solutions there are to the given quadratic equation. A positive discriminant indicates that the quadratic has two distinct real number solutions. A discriminant of zero indicates that the quadratic has a repeated real number solution.
Step-by-step explanation:
The discriminant of the quadratic equation g is negative.
In algebra, the discriminant of a quadratic equation plays a crucial role in determining the nature of its roots. For a quadratic equation of the form ax² + bx + c = 0, the discriminant is given by Δ = b² - 4ac. Depending on whether the discriminant is positive, zero, or negative, we can determine the types of roots the equation possesses.
When the discriminant is negative, it implies that the quadratic equation has no real roots. In this case, the graph of the quadratic equation does not intersect the x-axis at all, indicating that it has complex roots. These complex roots are a pair of complex conjugates of the form (p + qi) and (p - qi), where p and q are real numbers and i is the imaginary unit (√(-1)).
