How many milliliters of full-strength Sustacal are needed to prepare 240ml of half-strength sustacal?
The question is incomplete, the complete question is;
How many milliliters of full-strength Sustacal are needed to prepare 240 mL of half-strength Sustacal?
1. 120 mL
2. 240 mL
3. 360 mL
4. 480 mL
Answer:
120 mL
Step-by-step explanation:
From the question, we can see that the full strength solution is supposed to contain 240 ml of Sustacal .
If that is so, we can get a half strength solution by using only 120 ml of full strength solution and making up the remaining volume with water. This solution now has half the strength of a 240 ml full strength solution.

The selling cost for Stefan bicycle = $114 and
the selling cost of a helmet = $18.
The total cost for Jin is 120% of the money spent.
Let us assume purchasing cost of a bicycle = $x.
Purchasing cost of a halmet = $y.
For bicycle
120% of x is $114
=> 1.20 × x = 114
Dividing both sides by 1.20, we get
x=$95.
For helmet.
120% of y is $18.
=> 1.20 × y = 18.
Dividing both sides by 1.20, we get
y = $15.
Therefore, Stefan spent originally to buy a bike $95 and $15 to buy a helmet.
$114 - 95 = $19
$18 - 15 = $3.
Therefore, he made $19 by selling the bicycle and $3 by selling the helmet to Jin.

X+1/x-6 times 7x/x+2
Answer:
7x^2+7x/x^2-4x-12
Step-by-step explanation:
Given the expression
X+1/x-6 times 7x/x+2
Rewrite
X+1/x-6 * 7x/x+2
= 7x(x+1)/(x-6)(x+2)
= 7x^2+7x/x^2+2x-6x-12
= 7x^2+7x/x^2-4x-12
Hence the product of both function is expressed as 7x^2+7x/x^2-4x-12

b) x = 19
c) X = 20
d) x = 21
Answer:
D. x = 21
Step-by-step explanation:
So a straight line is equal to 180º and that's what we're trying to figure out here. Set both equations to equal 180, it should look like:
5x + 4x - 9 = 180
Now we just solve!
5x + 4x - 9 = 180
5x + 4x = 9x
9x - 9 = 180
+9 +9
------------------
9x = 189
Divide both sides by 9 to get x by itself.
189/9 = 21
x = 21

the number of successes and the sample size are given for a simple random sample from a population. determine the sample proportion for x
Complete Question
The number of successes and the sample size for a simple random sample from a population are given below. x-4, n 200, [tex]H_o[/tex]: p- 0.01, Ha p>0.01, a 0.05 . determine the sample proportion of x
Answer:
The sample proportion of x is [tex]\^ p = 0.02[/tex]
Step-by-step explanation:
From the question we are told that
The number of success is x = 4
The sample size is n = 200
The null hypothesis is [tex]H_o : p = 0.01[/tex]
The alternative hypothesis is [tex]H_a : p > 0.01[/tex]
The level of significance is [tex]\alpha = 0.05[/tex]
Generally the sample proportion of x is mathematically represented as
[tex]\^ p = \frac{x}{n}[/tex]
=> [tex]\^ p = \frac{4}{200}[/tex]
=> [tex]\^ p = 0.02[/tex]

Shaniqua brings home $250 per week working 25 hours. She is able to save $30 of her earnings each week.
Shaniqua wants to have $750 saved at the end of 15 weeks. She is allowed to work up to 30 hours per week if she
wants. She can save all the money earned working extra hours. How many hours (as a whole number) each week
must Shaniqua work to save $750 at the end of 15 weeks? Show your work.
Answer: She'd have to work 27 hours a Week because by her working 2 more hours shed be able to save up 50 a week.
Explanation: 750 divided by 15 (the weeks) is 50. Shed need to save 50 a week instead of 30 to reach her goal and the amount 50 divided by the number of hours she works (25) is 2. Add the 2 to 25 and you get 27 weeks.

Graph the equation y=-x^2+12x-32y on the accompanying set of axes. You must plot 5 points including the roots and the vertex.
The vertex of the quadratic function y = - x² + 12 · x - 32 is located at point (0, - 20) and the roots of the abovementioned are points (4, 0) and (8, 0), respectively.
How to graph a quadratic function
By fundamental algebra theorem we need at least three no coplanar different points to graph quadratic functions. First, we determine 5 different points, then we pass the curve through the five points and finally we identify the roots and the vertex.
If we know that (- 16, - 480), (- 12, - 320), (- 8, - 192), (- 4, - 96), (0, - 32), then the graph of the quadratic function is shown in the image.
The vertex of the quadratic function y = - x² + 12 · x - 32 is located at point (0, - 20) and the roots of the abovementioned are points (4, 0) and (8, 0), respectively.

Test the claim that the mean GPA of night students is larger than 2 at the .025 significance level. The null and alternative hypothesis would be: H 0 : μ = 2 H 0 : μ = 2 H 1 : μ > 2 H 1 : μ > 2 H 0 : p = 0.5 H 0 : p = 0.5 H 1 : p ≠ 0.5 H 1 : p ≠ 0.5 H 0 : p = 0.5 H 0 : p = 0.5 H 1 : p > 0.5 H 1 : p > 0.5 H 0 : μ = 2 H 0 : μ = 2 H 1 : μ < 2 H 1 : μ < 2 H 0 : p = 0.5 H 0 : p = 0.5 H 1 : p < 0.5 H 1 : p < 0.5 H 0 : μ = 2 H 0 : μ = 2 H 1 : μ ≠ 2 H 1 : μ ≠ 2 Based on a sample of 60 people, the sample mean GPA was 2.02 with a standard deviation of 0.06 The test statistic is (to 3 decimals) The critical value is (to 3 decimals) Based on this we fail to reject the null hypothesis reject the null hypothesis
Answer:
[tex]H_0: \, \mu = 2[/tex].
[tex]H_1:\, \mu > 2[/tex].
Test statistics: [tex]z \approx 2.582[/tex].
Critical value: [tex]z_{1 - 0.025} \approx 1.960[/tex].
Conclusion: reject the null hypothesis.
Step-by-step explanation:
The claim is that the mean [tex]\mu[/tex] is greater than [tex]2[/tex]. This claim should be reflected in the alternative hypothesis:
[tex]H_1:\, \mu > 2[/tex].
The corresponding null hypothesis would be:
[tex]H_0:\, \mu = 2[/tex].
In this setup, the null hypothesis [tex]H_0:\, \mu = 2[/tex] suggests that [tex]\mu_0 = 2[/tex] should be the true population mean of GPA.
However, the alternative hypothesis [tex]H_1:\, \mu > 2[/tex] does not agree; this hypothesis suggests that the real population mean should be greater than [tex]\mu_0= 2[/tex].
One way to test this pair of hypotheses is to sample the population. Assume that the population mean is indeed [tex]\mu_0 = 2[/tex] (i.e., the null hypothesis is true.) How likely would the sample (sample mean [tex]\overline{X} = 2.02[/tex] with sample standard deviation [tex]s = 0.06[/tex]) be observed in this hypothetical population?
Let [tex]\sigma[/tex] denote the population standard deviation.
Given the large sample size [tex]n = 60[/tex], the population standard deviation should be approximately equal to that of the sample:
[tex]\sigma \approx s = 0.06[/tex].
Also because of the large sample size, the central limit theorem implies that [tex]Z= \displaystyle \frac{\overline{X} - \mu_0}{\sigma / \sqrt{n}}[/tex] should be close to a standard normal random variable. Use a [tex]Z[/tex]-test.
Given the observation of [tex]\overline{X} = 2.02[/tex] with sample standard deviation [tex]s = 0.06[/tex]:
[tex]\begin{aligned}z_\text{observed}&= \frac{\overline{X} - \mu_0}{\sigma / \sqrt{n}} \\ &\approx \frac{\overline{X} - \mu_0}{s / \sqrt{n}} = \frac{2.02 - 2}{0.06 / \sqrt{60}} \approx 2.582\end{aligned}[/tex].
Because the alternative hypothesis suggests that the population mean is greater than [tex]\mu_0 = 2[/tex], the null hypothesis should be rejected only if the sample mean is too big- not too small. Apply a one-sided right-tailed [tex]z[/tex]-test. The question requested a significant level of [tex]0.025[/tex]. Therefore, the critical value [tex]z_{1 - 0.025}[/tex] should ensure that [tex]P( Z > z_{1 - 0.025}) = 0.025[/tex].
Look up an inverse [tex]Z[/tex] table. The [tex]z_{1 - 0.025}[/tex] that meets this requirement is [tex]z_{1 - 0.025} \approx 1.960[/tex].
The [tex]z[/tex]-value observed from the sample is [tex]z_\text{observed}\approx 2.582[/tex], which is greater than the critical value. In other words, the deviation of the sample from the mean in the null hypothesis is sufficient large, such that the null hypothesis needs to be rejected at this [tex]0.025[/tex] confidence level in favor of the alternative hypothesis.
A flower bed is in the shape of a triangle with one side twice the length of the shortest side and the third side is 19 feet more than the length of the shortest side. Find
the dimensions if the perimeter is 163 feet.
What is the length of the shortest side?
The length of the shortest side is
This is simple as the perimeter is given. All you have to do is make an expression and then equate it to the perimeter.
Side lengths:
Shortest Side: [tex]x[/tex]
1st side: [tex]2x[/tex] (Given that it's twice the length of the shortest of twice of [tex]x[/tex])
3rd side: [tex]x + 19[/tex] (Given that it's 19 more than the length of the shortest side or [tex]x[/tex])
Since the perimeter is just the addition of all the sides of the shape, the perimeter is going to be the addition of all the expression we made.
So the final expression is going to be: [tex]x + 2x + x + 19[/tex]
This is nothing but the perimeter so we can therefore equate it to [tex]163[/tex]
[tex]x + 2x + x + 19 = 163[/tex]
Now we solve the equation. Here it goes!:
[tex]4x + 19 = 163\\4x = 163 - 19\\4x = 144\\x = 144/4 = 36[/tex]
Therefore, [tex]x = 36[/tex]
So now we plug them into the previous expressions we made for the sides and you get:
Shortest side: [tex]36[/tex]
1st side: [tex]72[/tex]
3rd side: [tex]55[/tex]
And also, the length of the shortest side is [tex]36[/tex] as mentioned previously :D
