Answer:
x =< -13/24
Step-by-step explanation:
Solve the equation: –5x –4 = 16
Let's solve your equation step-by-step.
−5x−4=16
Step 1: Add 4 to both sides.
−5x−4+4=16+4
−5x=20
Step 2: Divide both sides by -5.
−5x /−5 =20/-5
x=−4
What is the value of x?
Enter your answer in the box.
Answer:
X = 40
Step-by-step explanation:
{ 2 (x + 10)} = (3x - 30)
2x + 10 = 3x - 30
10 = 3x - 2x - 30
10 + 30 = 1x
40 = 1x
X = 40

28. The difference between two
numbers is 80. If the ratio of two
numbers is 3:5, find the
numbers *
Answer:
We set up 2 equations:
n - m = 80 so "n" is the larger number
A) n - m = 80
B) m / n = .6
A) n = 80 + m
B) m = .6 n so B) n = (5/3) m
We substitute B) into A)
(5/3) m = 80 + m
(2/3) m = 80
m = 1.5 * 80
m = 120
n = 200

???
The system of inequalities represents the given scenario are w ≤ l – 10 and 2l + 2w > 62Therefore, option D is the correct answer.
What is the perimeter of a rectangle?The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).
Given that, the perimeter of a rectangular pool is more than 62 meters.
Let the length of a rectangular pool be l.
The width is at least 10 meters less than the length.
w≤ l-10
So, 2(l+w)>62
2l+2w≥62
Therefore, option D is the correct answer.

Step-by-step explanation:
The cost of the family’s cell phone plan rose from $130 to $194 when they added a phone for their daughter. What was the percent of increase?
Answer:
49%Step-by-step explanation:
Step one:
initial price=$130
final price=$194
Step two:
we know that the percent increase is given as
% increase= final-initial/initial
substituting we have
% increase= 194-130/130*100
% increase= 64/130*100
% increase= 0.49*100
% increase= 0.49*100= 49%
therefore the percent increase is 49%
Help I'm being timed I don't understand how to do this at all and I would need and example I need to explain how I calulated my answer
Answer:
Look at the numerators, how do you change 90.6 to 22.65? You divide 90.6, but by what? So, we divide to get the number we divide by, which is 4.
90.6 divided by 22.65 = 4
Now, we do the same to the 12 2/5. Since we divided the top by 4, we'll divide 12 2/5 by 4 as well. Change 12 2/5 to a decimal and then divide to get the denominator of the second number.
12 2/5 divided by 4 = 3.1
So, 90.6/12 2/5 = 22.65/3.1

Miniature dachshunds, a dog breed with very short legs, run at an average speed of 13 mph with a standard deviation of 1.6 mph. Labrador retrievers run at an average speed of 22 mph with a standard deviation of 2.8 mph. Both breeds' running speeds are Normally distributed. A miniature dachshund runs down a street at 14.8 mph. It is chasing a Labrador that is running 25 mph.
Complete Question
Miniature dachshunds, a dog breed with very short legs, run at an average speed of 13 mph with a standard deviation of 1.6 mph. Labrador retrievers run at an average speed of 22 mph with a standard deviation of 2.8 mph. Both breeds' running speeds are Normally distributed. A miniature dachshund runs down a street at 14.8 mph. It is chasing a Labrador that is running 25 mph, use their z-scores to find which dog is running faster relative to its breed
Answer:
Miniature dachshunds is faster
Step-by-step explanation:
From the question we are told that
The speed of the Miniature dachshunds is [tex]x = 14.8 \ mph[/tex]
The mean for the Miniature dachshunds is [tex]\mu_1 = 13 \ mph[/tex]
The standard deviation for the Miniature dachshunds is [tex]\sigma_1 = 1.6 \ mp h[/tex]
The speed of the Labrador is [tex]y = 25 \ mph[/tex]
The mean for the Labrador is [tex]\mu_2 = 22 \ mph[/tex]
The standard deviation for the Labrador is [tex]\sigma_2 = 2.8 \ mp h[/tex]
Generally the z-score for the Miniature dachshunds is
[tex]z_1 = \frac{x- \mu_1 }{\sigma_1}[/tex]
=> [tex]z_1 = \frac{14.8 - 13 }{1.6}[/tex]
=> [tex]z_1 = 1.125[/tex]
Generally the z-score for the Labrador is
[tex]z_2 = \frac{x- \mu_2 }{\sigma_2}[/tex]
=> [tex]z_2 = \frac{25 - 22 }{2.8}[/tex]
=> [tex]z_2 = 1.071[/tex]
From the value obtained we see that [tex]z_1 > z_2[/tex] , hence miniature dachshund is faster

If the population of a study is finite and just covers only a small set of data and the time and cost of the study is of no concern to the one who is conducting the study then it is better to take samples rather than conduct the study over the whole population
Answer:
False
Step-by-step explanation:
The above statement is not correct since the time and cost of the study is of no concern to the one who is conducting the study, The person conducting the study having ample time and resource, means that it would be better for the person to expand the scope of the study by conducting it over the whole population because that will give a more accurate result rather than conducting the study over a few samples .

what is the answer to this..√25x+10=15
Answer:
x = 1.
Step-by-step explanation:
√25x + 10 = 15
√25x = 15 - 10
√25x = 5
squaring both sides:
(√25x)^2 = (5)^2
25x = 25
hence x = 1.
7x+4y=24

Clifford works 40 hours per week while working as a laboratory technician. He earns $653.60 for each week of work. How much does he earn in an hour? How much money does he make in 4 weeks?
Answer:
Total income= $2,614.4
Step-by-step explanation:
Giving the following information:
Workweek hours= 40
Total salary per week= $653.6
First, we need to calculate the monetary value of an hour:
Earn per hour= total salary/number of hours
Earn per hour= 653.6 / 40
Earn per hour= $16.34
Now, the total income for 4 weeks:
Total income= 653.6*4
Total income= $2,614.4
