Q = x^2 - 15x + 56 = 0
Answer:
x = 8
x = 7
Step-by-step explanation:
Solving x2-15x+56 = 0 by the Quadratic Formula .
According to the Quadratic Formula, x , the solution for Ax2+Bx+C = 0 , where A, B and C are numbers, often called coefficients, is given by :
- B ± √ B2-4AC
x = ————————
2A
In our case, A = 1
B = -15
C = 56
Accordingly, B2 - 4AC =
225 - 224 =
1
Applying the quadratic formula :
15 ± √ 1
x = —————
2
So now we are looking at:
x = ( 15 ± 1) / 2
Two real solutions:
x =(15+√1)/2= 8.000
or:
x =(15-√1)/2= 7.000
I really need to know what a dependent variable is. Can anyone explain better that google?
Answer:
A variable that depends on one or more other variables. For equations such as y = 3x – 2, the dependent variable is y. The value of y depends on the value chosen for x. Usually the dependent variable is isolated on one side of an equation.

A fruit stand has to decide what to charge for thier produce. They need $10 for 4 apples
Answer:
$10 = 4x
Step-by-step explanation:
The "x" would represent how much the apples would cost. So next you would divide both sides by 4x and then it would leave you with 2/5.

can someone ease explain how this is possible. right now I have tried everything from the back of my head and nothing seems to work. Thanks!
Answer:
x= 1/a-1/b
Step-by-step explanation:
use math.way
The answer to your question is 1 because:
'ax' and 'bx' have no values, they are missing numbers.
We have to cancel out one 1, and our answer is 1.

At a shelter, 35% of the dogs are puppies. There are 200 at the shelter. How many are puppies?
Answer:
Step-by-step explanation:
Percentage of purebred dogs in shelters: 25% Number cats and dogs adopted from shelters each year: 4 million. Percentage of cats euthanized in shelters: 70% Percentage of total shelter intake comprised of cats: Approximately 50% (but in some regions 2/3 of shelter population is cats)
Answer:
70 puppies
Step-by-step explanation:
Find 10% which is 200÷10=20
20*3=60=30%
20÷2=10=5% so 60+10=70 puppies

Two accounting professors decided to compare the variance of their grading procedures. To accomplish this, they each graded the same 10 exams, with the following results:
Mean Grade Standard Deviation
Professor 1 79.3 22.4
Professor 2 82.1 12.0
What is the alternate hypothesis?
Answer:
Alternative hypothesis:
[tex]\mathbf{H_a = \sigma_1^2 \ne \sigma_2^2}[/tex]
Step-by-step explanation:
Given that:
Sample 1:
Sample size [tex]n_1[/tex] = 10
Sample mean [tex]\overline x_1[/tex] = 79.3
Standard deviation [tex]\sigma_1[/tex] = 22.4
Sample 2:
Sample size [tex]n_2[/tex] = 10
Sample mean [tex]\overline x_2[/tex] = 82.1
Standard deviation [tex]\sigma_2[/tex] = 12.0
To find the alternative hypothesis.
The null and alternative hypothesis can be computed as follows:
Null hypothesis:
[tex]\mathbf{H_o = \sigma_1^2 = \sigma_2^2}[/tex]
Alternative hypothesis:
[tex]\mathbf{H_a = \sigma_1^2 \ne \sigma_2^2}[/tex]
Since, alternative hypothesis is ≠, it shows that it is a two tailed test.

Step-by-step explanation:
Suppose babies born in a large hospital have a mean weight of 3831 grams, and a variance of 108,900. If 65 babies are sampled at random from the hospital, what is the probability that the mean weight of the sample babies would differ from the population mean by less than 45 grams
Answer:
the probability that the mean weight of the sample babies would differ from the population mean by less than 45 grams is 0.7284
Step-by-step explanation:
Given that
mean weight = 3831 grams,
variance = 108,900
sample size n = 65
the probability that the mean weight of the sample babies would differ from the population mean by less than 45 grams = ?
Now standard error of mean = √( 108900 / 65 ) = 40.9314
z = +/- (45/40.9314)
z = +/-1.0994
so
P( -1.0994 <z< 1.0994 ) = P( z<1.0994 ) - (p<-1.0994 )
= 0.8642 - 0.1358
= 0.7284
Therefore the probability that the mean weight of the sample babies would differ from the population mean by less than 45 grams is 0.7284
Equation for (-2,-5) and (1,-3) in slope-intercept form
Answer:
y=2/3x-11/3
Step-by-step explanation:
First, find the slope.
m= y2-y1/x2-x1
-3+5/1+2 = 2/3
Slope is 2/3
Now, pick one of the coordinates and use that and the slope to put it in point-slope form.
Point slope form: y-y1=m(x-x1)
Let's use (1,-3)
y+3=2/3(x-1)
Distribute 2/3 to (x-1) and simplify to get the equation in slope-intercept form.
y+3=2/3x-2/3
y=2/3x-11/3
Answer:
y=2/3x-11/3
Step-by-step explanation:
use slope formula and slope intercept form. y=mx+b

Given:
The graph of a function f(x).
To find:
The solution set for f(x)>0 and f(x)≤0.
Solution:
From the given graph it is clear that, the function intersect the x-axis at 3 points, i.e., x=-4, -3 and -2.
The graph is above the x-axis before -4 and between -3 and -2.
So, the solution set for f(x)>0 is [tex](-\infty,-4)\cup (-3,-2)[/tex].
The graph is below the x-axis between -4 and -3; and after -2. For f(x)≤0, those values are in the solution set for which f(x)=0, i.e., x-intercepts. So, we use close brackets in the interval notation.
So, solution set for f(x)≤0 is [tex][-4,-3]\cup [-2,\infty)[/tex].

Step-by-step explanation:
Answer:
Do multiplications first, then simplify the equation from left to right. Therefore, your answer should be 18.
Step-by-step explanation:
3 - 5 + 4 + 2 × 6
= 3 - 5 + 4 + 12
= 2 + 4 + 12
= 6 + 12
= 18

Answer:
120 such cubes could fit in the prism.
Step-by-step explanation:
Volume of prism = length × breadth × height
[tex] = \frac{5}{3} \times \frac{4}{3 } \times 2[/tex]
[tex] = \frac{40}{9} cm {}^{3} [/tex]
___________________________________
Volume of cube = a³
[tex] = ( \frac{1} {3}) {}^{3} [/tex]
[tex] = \frac{ {1}^{3} }{ {3}^{3} } [/tex]
[tex] = \frac{1}{27} cm {}^{ 3} [/tex]
____________________________________

A dressmaker has 75 yards of lace . It takes 1 1/2 yards of lace to decorate one pocket . How many pockets can she decorate with the lace she has
Answer:
50 pockets
Step-by-step explanation:
Given
[tex]Total = 75\ yd[/tex]
[tex]Pocket = 1\frac{1}{2}yd[/tex]
Required
Determine the number of pockets
To calculate the required , we make use of:
[tex]Pockets = \frac{75yd}{1\frac{1}{2}yd}}[/tex]
[tex]Pockets = \frac{75}{1\frac{1}{2}}}[/tex]
Convert the denominator to decimal
[tex]Pockets = \frac{75}{1.5}[/tex]
[tex]Pockets = 50[/tex]
Hence, she can lace 50 minutes
