Step-by-step explanation:
joe spend 1 1/3 hours studying for his math test. randy studied for 1/2 the amou t the time that joe did. what fraction of an hour did randy spend studying
Step-by-step explanation:
Lets convert 1 1/3 into improper fraction.
[tex]1 \frac{1}{3} = \frac{1 \times 3 + 1}{3} \\ = \frac{4}{3} [/tex]
Since Randy studied half the above time,
Randy Studied:
[tex] \frac{1}{2} \times \frac{4}{3} \\ = \frac{1 \times 4}{2 \times 3} \\ = \frac{4 \div 2}{6 \div 2} \\ = \frac{2}{3} hours[/tex]
On a survey of students at CAMS, 75% of students said
they preferred Soda instead of Juice.
6. If 420 students preferred Soda, how many students
did they survey in total?
Answer:Total number of students surveyed =560
Step-by-step explanation:
Number of students who preferred soda =420
Percentage of students who preferred Soda =75%
Percentage of students who preferred juice =100-75%=25%
Using the formula,
Percentage of students who preferred Soda x total number of students surveyed =Number of students who preferred soda
Therefore we have that
total number of students surveyed =Number of students who prefeerd juice/Percentage of students who preferred Soda
Total number of students surveyed =420/75%
=560
Simplify the expression to a + bi form:
(3+10i)-(-12-8i)
Answer:
15 + 18i
Step-by-step explanation:
(3 + 10i) - (-12 - 8i) = 3 + 10i - 12*(-1) - 8i*(-1)
= 3 + 10i +12 + 8i
= 3 + 12 + 10i + 8i {Combine like terms}
= 15 + 18i

Answer:
√193
Step-by-step explanation:
pathagorus theorem:
[tex]( {hyp})^{2} = ( {base)}^{2} + ( {perp)}^{2} [/tex]
hyp=x , base= 12 , perp= 7
subtitles all values in formula:
we get
x^2 = 12^2 + 7^2
x^2 = 144 +49
x= √193
The missing side of this right triangle is, 13.90 units.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
We have to given that;
The base of the triangle = 12
The perpendicular distance of the triangle = 7
Now, We know that;
Pythagoras theorem stated as;
⇒ Hypotenuse² = Base² + Perpendicular²
⇒ x² = 12² + 7²
⇒ x² = 144 + 49
⇒ x² = 193
⇒ x = √193
⇒ x = 13.90
Thus, The missing side of this right triangle is, 13.90 units.

Find the perimeter of the polygon with the vertices G(2, 4), H(2,−3), J(−2,−3), and K(−2, 4).
Answer:
22 units
Step-by-step explanation:
Graphed to solve.
Width:
The distance between points K and G, and points J and H is both 4 units. So for both distances between the set of points will be 8 units total.
Length:
The distance between points G and H, and points J and K is both 7 units. So for both distances between the sets of points will be 14 units total.
14 + 8 = 22
!!!50 POINTS PLZ HELPPPP!!!!!! Which of the following shows the graph of y = –(2)x – 1?
What is the slope-intercept equation of the line going through (3, -6) and
(1,2)?
A. y=-4x+ 2
B. y = -4x + 1
O c. y-2 = -4(x - 1)
O D. y=-4x + 6
Hi there!
[tex]\large\boxed{D. \text{ }y = -4x + 6}[/tex]
To derive an equation given the points, we can use the slope formula:
[tex]slope = \frac{y_{2}-y_{1}}{x_{2}-x{1}}[/tex]
Plug in the corresponding coordinates:
[tex]slope = \frac{-6-2}{3-1}[/tex]
Simplify:
[tex]slope = \frac{-8}{2} = -4[/tex]
Therefore, we have:
y = -4x + b
Plug in the x and y values for a coordinate to solve for b:
2 = -4(1) + b
2 = -4 + b
b = 6
The equation is:
y = -4x + 6. The correct answer is D.
Wheaties cereal is claimed to have an average of 3 grams of dietary fiber per serving. We want to test this hypothesis and to see whether we believe that is true or that the mean amount of fiber is significantly different from 3 grams. A random sample of 25 servings was taken and it yielded a sample mean of 3.4 grams with the sample standard deviation in the amount of fiber, s = .8 grams.
Assume that software has determined the p-value to be.02.
What would your decision be on this hypothesis test if everything is the same except that we change the level of significance for the test to.01?
Fail to reject the null hypothesis at the 1% level of significance.
Reject the null hypothesis at the 1% level of significance,
Answer:
The calculated value t = 2.5>2.326 at 0.01 level of significance
The null hypothesis is rejected at a 0.01 level of significance.
Wheaties cereal is not claimed to have an average of 3 grams of dietary fiber per serving
Step-by-step explanation:
Step(i):-
Given that the average of dietary fiber per serving μ = 3 grams
Given that the mean of the sample x⁻ = 3.4 grams
Given that the standard deviation of the sample (S) = 0.8 grams
Level of significance = 0.01
Critical value = 2.326
Step(ii):-
Null hypothesis: H₀: μ = 3 grams
Alternative Hypothesis: H₁: μ ≠ 3 grams
Tets statistic
[tex]t = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }[/tex]
[tex]t = \frac{3.4-3 }{\frac{0.8}{\sqrt{25} } }[/tex]
t = 2.5
The calculated value t = 2.5>2.326 at 0.01 level of significance
The null hypothesis is rejected at a 0.01 level of significance.
Final answer:-
Wheaties cereal is not claimed to have an average of 3 grams of dietary fiber per serving
Solve for x, show work!
Answer: x=3
Step-by-step explanation:
One of the properties of diagonals of a rectangle is that they bisect each other, meaning that four segments are equal.
For example, in this question, according to the property, AE, CE, DE, BE will be equal.
Solve:
AE=CE
AE+CE=AC
CE+CE=AC
DB=AC
DB=2CE
(18)=2(4x-3)
18=8x-6

The solution of Equation 2x² + x -3 =0 by factoring is 1 and -3/2.
What is Factorization?The breaking or decomposition of an entity (such as a number, a matrix, or a polynomial) into a product of another entity, or factors, whose multiplication results in the original number, matrix, etc., is known as factorization or factoring in mathematics.
We have the equation 2x² + x -3 =0
Now, factorizing the above equation using splitting the middle term we get
2x² + x -3 =0
2x² + 3x - 2x -3 =0
x( 2x + 3) - (2x+ 3)= 0
(2x + 3)(x - 1)= 0
x = -3/2 or 1.

need please solving for x
Answer:
x = 15
Step-by-step explanation:
Corresponding sides of similar shapes are proportional to each other. Thus:
(10 + 2)/10 = (x + 3)/x
12/10 = (x + 3)/x
Cross multiply
12*x = (x + 3)*10
12x = 10x + 30
12x - 10x = 30
2x = 30
x = 30/2

HELP NEED SOON!! A store receives a shipment of 5,000 MP3 players. In a previous shipment of 5,000 MP3 players, 300 were
defective. A store clerk generates random numbers to simulate a random sample of this shipment. The
clerk lets the numbers 1 through 300 represent defective MP3 players, and the numbers 301 through
5,000 represent working MP3 players. The results are given.
4,942 368 110 4,758 4,452 610 773 171 460 2,699
Based on this sample, how many of the MP3 players might the clerk predict would be defective?
The manager would expect
defective players in the shipment.
Answer:
2?
