I will give brainliest Blue whales eat an average of 5,000 pounds of fish daily, with a standard deviation of 850 pounds. Approximately what percentage of blue whales eat more than 7,550 pounds of fish?
(7,550 - 5,000) / 850 = 3 standard deviations.
The percentage could vary depending on the bell curve diagram your professor uses. I was taught that anything more than 3 standard deviations is 0.15%. So, only about 0.15% of blue whales eat more than 7,550lbs of fish.
Answer:
the answer is 0.15 percent, give the person above me brainlyest for helping!

Monica is a lawyer who earns $8,322.65 every month. She spends $830.98 on rent, $210.36 on food, and $120.45 on gas every month. After these expenses, she has $ left from her earnings.
Answer:
Money left from her earning after expenses is $ 7160.86
Step-by-step explanation:
Money earned by Monica every month = $ 8322.65
Money spend on rent = $ 830.98
Money spend on food = $ 210.36
Money spend on gas every month = $ 120.45
Money left from her earning = 8322.65 - ( 830.98 + 210.36 + 120.45 )
= 8322.65 - 1161.79
= $ 7160.86
Answer:
Money left from her earning after expenses is $ 7160.86
Step-by-step explanation:
Money earned by Monica every month = $ 8322.65
Money spend on rent = $ 830.98
Money spend on food = $ 210.36
Money spend on gas every month = $ 120.45
Money left from her earning = 8322.65 - ( 830.98 + 210.36 + 120.45 )
= 8322.65 - 1161.79
= $ 7160.86
Therefore. Money left from her earning after expenses is $ 7160.86

6y - 5z = -8
3z = -6
4x - 3y - 2z= 21
Answer:
x = 2 y = - 3z = - 2Step-by-step explanation:
6y - 5z = -8 .......... Equation 1
3z = -6 ................... Equation 2
4x - 3y - 2z= 21...... Equation 3
First solve for z in Equation 2
That's
3z = - 6
Divide both sides by 3
z = - 2Next substitute the value of z into Equation 1 in order to find y
We have
6y - 5(-2) = - 8
6y + 10 = - 8
6y = - 8 - 10
6y = - 18
Divide both sides by 6
y = - 3Finally substitute the values of y and z into Equation 3 to find the value of x
That's
4x - 3(-3) - 2(-2) = 21
4x + 9 + 4 = 21
4x + 13 = 21
4x = 21 - 13
4x = 8
Divide both sides by 4
x = 2So the solutions are
x = 2 y = - 3z = - 2Hope this helps you
Linear equation
4X-12+3x+9
Steps to solve:
4x - 12 + 3x + 9
~Combine like terms
(4x + 3x) + (-12 + 9)
~Simplify
7x - 3
Best of Luck!
Answer:
X = 3/7
Step-by-step explanation:
4X - 12 + 3X + 9 = 0 (separate them)
4X + 3X = 12 - 9 (add)
7X = 3 (divide 7 on both sides)
X = 3/7
How many solutions does the system have?
2x+3y=6
-3x+5y=-15
Answer:
one solution
Step-by-step explanation:
2x+3y=6 multiply this equation with 3
-3x+5y=-15 multiply this equation with 2
so
6x+9y=18
-6x+10y=-15
----------------------
add these equation
so 6x-6x+9y+10y=18-15
19y=3
y=3/19
so 2x+3*3/19=6 multiply this equation with 19
2x*19+9=6*19
38x+9=114
-9 -9
38x=105
x=105/38
A student multiplies (4+5i) (3-2i) incorrectly and obtains 12-10i. What is the student's mistake? Select the two correct answers. A. They multiplied the second number by the real part of the first number. B. In the multiplication of the imaginary parts, the student forgot to square the i. C. The student has only multiplied the real parts and the imaginary parts. D. The student has added the real parts and multiplied the imaginary parts. E. The student has multiplied the second number by the imaginary part of the first number.
Answer:
B. In the multiplication of the imaginary parts, the student forgot to square the i. C. The student has only multiplied the real parts and the imaginary parts.Step-by-step explanation:
Before we figure out the student mistake, let us find the product of the complex numbers ourselves first.
(4+5i) (3-2i)
open the parenthesis
= 4(3)-4(2i)+3(5i)+5i(-2i)
= 12-8i+15i-10i²
Note that in complex number, i² = -1, hence the expression will become;
= 12-8i+15i-10(-1)
= 12-8i+15i+10
collect like terms by separating the real from imaginary part
= 12+10-8i+15i
= 22+7i
From the students answer i.e 12-10i, it can be concluded that;
In the multiplication of the imaginary parts, the student forgot to square the i and the student has only multiplied the real parts and the imaginary parts 4 and 3 to get 12

Step-by-step explanation:
A hot air balloon ascended to a height of 25 meters 2 minutes after launch. After some time, the balloon's altitude began to change by -2⅕ meters every minute for 7 minutes. To avoid a tree, the balloon flew up by 8½ meters. What is the new altitude of the balloon? expression for problem?
Answer:
18.1 m
Step-by-step explanation:
For this problem, we will simply use the initial height of 0 meters, the height of 25 meters after 2 minutes, the decline of 2.2 meters every minute for 7 minutes, and a final increase of 8.5 meters to find the final altitude of the ballon.
0m + 25m - 2.2m(7) + 8.5m = ?
25m - 15.4m + 8.5m = ?
9.6m + 8.5m = ?
18.1m = ?
Hence, the final altitude of the ballon is 18.1m.

What is the solution of log(t-3) = log(17-4t)?
Answer:
t=4
Step-by-step explanation:
Answer:
Solution: 4
Step-by-step explanation:
We are given that log(t - 3) = log(17 - 4t), and need to solve for the value of t. Start off by applying the log rule 'If log(f(x)) = log(g(x)) say, then f(x) = g(x).' Similarly the equation boils down to the following:
t - 3 = 17 - 4t
Solving this equation, we will receive our solution. Let's do it:
t - 3 = 17 - 4t,
t = 20 - 4t,
5t = 20,
t = 20/5 = 4 ✓
The previous solution is correct.

y - 13 = 3 ( x - 1 )
y - 13 = 3 x - 3
y = 3 x - 3 + 13
y = 3 x + 10
y - 4 = 3 x + 6
y - 4 = 3 ( x + 2

(Ticket sales) tickets for a community theater costs $10 for each main floor seat and $8 for each balcony seat. There are 400 seats on the main floor, and these seats were sold out for the evening performance. The total revenue from ticket sales was $5200. How many balcony seats were song?
Answer:
150
Step-by-step explanation:
400*10=4000
5200-4000=1200
1200 divided by 8 =150
Answer:
150 seats were sold.
Step-by-step explanation:
first do 10x400= 4000
then 5200-4000= 1200
divide that by how much balcony tickets cost, so 1200÷8= 150 seats
Determine whether the study is an observational study of an experiment. Explain.
In a survey of 1117 adults in a country, 54% said the country's leader should release all medical information that might affect their ability to serve The study is_____because it____a treatment to the adults.
Answer: Observational ; does not
Step-by-step explanation: The main distinguishing factor between an experimental study and an observational study lies in the administration of treatment to the participant of the study. In experimental study, some or all the participant in the study are subjected or exposed to a certain treatment and their response to such treatment. ON THE OTHER HAND, Observational study is usually employed when there is a need to gather information on a particular subject matter without directly influencing the participants. In the scenario above, participants were not given any TREATMENT as they were only required to gather information and not to measure the effect of a treatment.
