What is the value of x?
Answer:
X = 149
Step-by-step explanation:
A full circle is 360 degrees
Add 160+51=211
360-211=149
Answer:
x = 58
Step-by-step explanation:
The secant- tangent angle is half the difference of the intercepted arcs , then
[tex]\frac{1}{2}[/tex] (160 - x) = 51 ( multiply both sides by 2 )
160 - x = 102 ( subtract 160 from both sides )
- x = - 58 ( multiply both sides by - 1 )
x = 58

Solve the system of equations
2x+3y= 6
x+y=4
(6,-2)
(-2,6)
(-3, 4)
(0, 2)
Answer:
Step-by-step explanation:
2x+3y= 6 ========================>>> 2x + 3y = 6
x+y=4 ===== times both sides by 2 =====>>> 2x + 2y = 8
==== subtract these two equations ==>> (2x - 2x) + (3y - 2y) = 6 - 8
0x + y = -2
y = -2 so if x + y = 4 plug in -2 where y was
x + (-2) = 4 add 2 to both sides
x = 6
(6,-2)
(-2,6)
(-3, 4)
(0, 2)

1. Suppose that 35% of all patients admitted to a hospital's intensive care unit (ICU) have high blood pressure, 42% have some sort of infection, and 12% have both problems
Answer:
a) 65%
b) 28.57%
Step-by-step explanation:
Suppose that 35% of all patients admitted to a hospital's
intensive care unit have high blood pressure, 42% have some sort of infection, and 12% have both problems. Probabilities estimated from the data in ICU Admissions. (10POINTS)
(a) Find the probability that a randomly chosen patient in this ICU has either high blood pressure or an infection.
(b) Find the probability that a patient admitted to the ICU has high blood pressure given that an infection is present.
Solution:
Let H represent the people with high blood pressure and I represent the people with infection.
P(H) = 35% = 0.35, P(I) = 42% = 0.42, P(H ∩ I) = 12% = 0.12
Those with only high blood pressure = P(H ∩ I') = P(H) - P(H ∩ I) = 0.35 - 0.12 =0.23
Those with only infection = P(H' ∩ I) = P(I) - P(H ∩ I) = 0.42 - 0.12 =0.30
a) probability that a patient has either high blood pressure or an infection = P(H ∪ I)
P(H ∪ I) = P(H ∩ I') + P(H' ∩ I) + P(H ∩ I) = 0.23 + 0.3 + 0.12 = 0.65 = 65%
b) probability that a patient has high blood pressure given that an infection is present = P(H / I)
P(H / I) = P(H ∩ I) / P(I) = 0.12 / 0.42 = 0.2857 = 28.57%

The population of rabbits on an island is growing exponentially. In the year 1995, the population of rabbits was 1000, and by 1999 the population had grown to 1800. Predict the population of rabbits in the year 2003, to the nearest whole number.
Answer:
3,240
Step-by-step explanation:
The computation of the population of rabbits in the year 2003 is shown below:
Given that
In the year 1995, the population of the rabbits was 1000
And, in 1999 the population of the rabbits grown to 1,800
So there is an increase of
= (1800 - 1000) ÷ 1000
= 80%
So for 2003, the population of the rabbits is
= 1800 + (1800 × 0.80)
= 3,240
Given:
The population of rabbits on an island is growing exponentially.
In the year 1995, the population of rabbits was 1000, and by 1999 the population had grown to 1800.
To find:
Expected population of rabbits in the year 2003, to the nearest whole number.
Solution:
The exponential growth model is:
[tex]y=ab^t[/tex]
Where, a is the initial value, b is the growth factor, t is the number of years.
Let y be the population of rabbits t years after 1995.
In the year 1995, the population of rabbits was 1000, it can be written as (0,1000) and by 1999 the population had grown to 1800, it can be written as (4,1800).
For (0,1000),
[tex]1000=ab^0[/tex]
[tex]1000=a(1)[/tex]
[tex]1000=a[/tex]
For (4,1800) and a=1000, we get
[tex]1800=1000b^4[/tex]
[tex]\dfrac{1800}{1000}=b^4[/tex]
[tex]1.8=b^4[/tex]
[tex](1.8)^{\frac{1}{4}}=b[/tex]
[tex]b\approx 1.1583[/tex]
The required exponential model is:
[tex]y=1000(1.1583)^t[/tex] ...(i)
in year 2003, the number of years since 1995 is 8.
Putting t=8 in (i), we get
[tex]y=1000(1.1583)^8[/tex]
[tex]y=3240.1748[/tex]
[tex]y\approx 3240[/tex]
Therefore, the population of rabbits in the year 2003 is 3240.

solve the inequality -24< x - 3 - 8x
Answer:
x = 3
Step-by-step explanation:
-24 < x - 3 - 8x
-24 < -7x - 3
-24 + 3 = -21
-7x - 3 + 3 = -7x
-21 = -7x
-21 / -7 = 3
-7x / -7 = x
3 = x

The coordinates of point B are located at -5 on the number line, and Point A is located at -8 on the number line. The reflection of point A on the number line is the coordinates of point E.
What is Number Line?In math, a number line can be defined as a straight line with numbers arranged at equal segments or intervals throughout. A number line is typically shown horizontally and can be extended indefinitely in any direction.
The numbers on the number line increase as one moves from left to right and decrease on moving from right to left.
According to the given number line,
The coordinates of point B are located at -5 on the number line, and Point A is located at -8 on the number line. The reflection of point A on the number line is the coordinates of point E.
Thus, Point B is at -5 on the number line, whereas Point A is at -8 on the number line. Point E is the number line's reflection of point A.
