Determine the area under the standard normal curve that lies to the right of the z-score of 1.44. (Use a four-digit decimal. No rounding necessary.)
Answer:
The area is 0.0749
Step-by-step explanation:
The area under the standard normal curve represents probability and has a total value of 1
Now, to the right of the z-score 1.44, the area we are considering is the probability below;
P( z > 1.44)
To get this value, we need to use the standard normal distribution table
Checking this, the probability is
P( z > 1.44) = ) = 0.074934 which is 0.0749 for a four decimal digit

A square field has 3,844 sq. meters of land. What is the width of the field?
Answer:
The side length is 62 meters
Step-by-step explanation:
The area of a square is given by
A = s^2 where s is the side length
3844 m^2 = s^2
Take the square root of each side
sqrt( 3844 m^2) = sqrt(s^2)
62 m= s
The side length is 62 meters

Elijah is trying to make extra money on his summer vacation from school. He works two different jobs, earning $8 per hour babysitting and $10 per hour lifeguarding. How much money would Elijah earn in a week in which he worked 3 hours babysitting and 7 hours lifeguarding?
Answer:
$94
Step-by-step explanation:
8x + 10x = y
8 (3) + 10 (7) = y
24 + 70 = y
94 = y
Answer with step-by-step explanation:
If he were to work a full week, then 3 hours babysitting × 7 days a week × $8 for work = $168 for babysitting. 7 hours lifeguarding × 7 days a week × $10 for work = $490 for lifeguarding.
The total amount of money that Elijah would earn is $168 + $490 = $658

A purple hot-air balloon is 90 feet off the ground and rising at a rate of 7 feet per second. A yellow hot-air balloon is 120 feet off the ground and rising at a rate of 4 feet per second. Which equation could represent this situation and determine after how many seconds, s, the purple hot-air balloon will be the same height as the yellow hot-air balloon?
1 point
90 + 7s = 120 + 4s
7s + 120 = 4s + 90
90s + 7 = 120s + 4
11s = 210
90+7s = 120 + 4s
11s = 210

Suppose you have a total of $2.25 in dimes and
nickels. You have twice as many dimes, as nickels.
Which system of equations could be used to
determine how many of each coin you have?
Answer:
n = number of nickels
2n = number of dimes
n($0.05) + 2n($0.10) = $2.25
0.05n + 0.2n = 2.25
0.25n = 2.25
n = 2.25/0.25 = 9
2n = 2(9) = 18
You has 9 nickels and 18 dimes

For example if you have a function f(x) = x - 1, then x = 1 is a zero of this function because using it as x gives 1 - 1 = 0. The Riemann Zeta function has some zeros that are easy to find which are of little interest but there are some other ones that are harder to find which is why the are called non-trivial.
Solve this equation
100x + 300 = 200
Answer:
-1
Step-by-step explanation:
100x=200-300
100x=-100
100x/100=-100/100
x=-1
After solving this equation we get, 100x + 300 = 200 x = -1.
To solve this equation
100x + 300 = 200,
Subtract 300 on both side,
100x + 300 - 300 = 200 - 300
100x = -100
Divide 100 on both side,
x = -1
Therefore, After solving this equation 100x + 300 = 200 we get x = -1.
