The median of 2/3 and 4 is 2.33.
The median is the middle point in a dataset—half of the data points are smaller than the median and half of the data points are larger.
A data set's median value is the point where 50% of the data points have values that are lower or equal to it, and 50% of the data points have values that are higher or equal to it.
To arrange the data points in ascending order for a small data set, count the number of data points (n).
To get the rank of the data point whose value is the median when the number of data points is unequal, multiply the total by 1 and divide the results by 2.
Median = (2/3+4)/2 = 4.66/2 = 2.33
Thus, the median of 2/3 and 4 is 2.33.

. Out of 40 pupils only 30 pupils submitted their project on time
What percent of the pupils submitted their project on time?
Asked:
Given:
Operation:
Number Sentence:
Solution:
Answer:
Answer:
75 %
Step-by-step explanation:
To solve for the above question,
The percentage of pupils that submitted their project on time
= Number of pupils that submitted their project on time/Number of pupils × 100
Number of pupils that submitted their project on time = 30 pupils
Number of pupils = 40 pupils
= 30/40 × 100
= 75 %
The percent of the pupils that submitted their project on time is 75%

You are testing two food scales for accuracy by weighing two different types of foods. Use the drop-down menus to complete the statements about the scales' accuracy. Scale 1 Measured Weight Actual Weight 85 oz 100 oz Scale 2 Measured Weight Actual Weight 47 oz 50 oz CLEAR CHECK Because the object on Scale 1 weighs more than the object on Scale 2, each ounce of error results in a lesser percent error. Scale 1 was 15 ounces off and Scale 2 was 3 ounces off, so Scale 1 was % off and Scale 2 was % off.
Answer:
scale 1 was 15% off and SCALE 2 was 6% off
Step-by-step explanation:
Scale __ Measured Weight ____Actual Weight
1_________85 oz _______________100 oz
2 ________ 47 oz _______________ 50 oz
Percentage error :
[(|measured - actual |) ÷ actual] * 100%
Scale 1 :
|85 - 100| = 15 oz
15 / 100 * 100% = 15%
Scale 2 :
|47 - 50| = 3 oz
3 / 50 * 100% = 0.06 * 100% = 6%
Hence, scale 1 was 15% off while SCALE 2 was 6%

For h(x), to find out the maximum, you would need to use this formula: [tex]c-(\frac{b^{2} }{4a} )[/tex]
We are given the equation: [tex]h(x)=-x^{2}+4x-2[/tex].
So, a = -1, b = 4, and c = -2. Then, substitute the numbers into the formula:
h(x)'s maximum = [tex]c-(\frac{b^{2} }{4a} )[/tex]
= [tex](-2)-(\frac{(4)^{2} }{4(-1)} )[/tex]
= [tex](-2)-(\frac{16 }{-4} )[/tex]
= [tex](-2)-(-4)[/tex]
= [tex]2[/tex]
For g(x), to find out the maximum, just look at the highest point of y on the graph of the function, which is 2.
Thus, the answer you have chosen is the correct answer, which is choice 3: functions g and h have the same maximum of 2. Hope this helps :)

The volume of the rectangular prism is ________ cm3
Answer:
volume of rectangular prism =l×w×h
volume of rectangular prism =4cm×2cm×7cm
volume of rectangular prism =56cm³
Answer:
The volume of the rectangular prism is [tex]56cm^3[/tex]
Step-by-step explanation:
To find the volume of a rectangular prism, you need to multiply the length, width, and height of the rectangular prism altogether. In this case, the length is 4cm, the width is 2cm, and the height is 7cm. So the volume of the rectangular prism would be [tex]7*2*4[/tex] = [tex]7 * 8[/tex] = [tex]56cm^3[/tex].
A researcher wished to compare the effect of two stepping heights (low and high) on heart rate in a step-aerobics workout. A collection of 50 adult volunteers was randomly divided into two groups of 25 subjects each. Group 1 did a standard step-aerobics workout at the low height. The mean heart rate at the end of the workout for the subjects in Group 1 was = 90.00 beats per minute with a standard deviation of = 9 beats per minute. Group 2 did the same workout but at the high step height. The mean heart rate at the end of the workout for the subjects in Group 2 was = 95.08 beats per minute with a standard deviation of = 12 beats per minute. Assume that two groups are independent and the data are approximately Normal. Let and represent the mean heart rates we would observe for the entire population represented by the volunteers, if all members of this population did the workout using the low or high step height, respectively. Suppose the researcher had wished to test the hypotheses and . The P-value for the test is (use conservative value for the degrees of freedom)
Answer:
The answer is "between 0.10 and 0.05".
Step-by-step explanation:
For sample 1:
[tex]n_1 = 25\\\\\bar{x_1} = 90.00\\\\ s_1 = 9\\\\[/tex]
For sample 2:
[tex]n_2 = 25\\\\ \bar{x_2} = 95.08\\\\ S_2 = 12\\\\[/tex]
Calculating the null and alternative hypotheses:
[tex]H_O : \mu_1 = \mu_2 \\\\ H_Q : \mu_1 <\mu_2[/tex]
Calculating the test statistic:
[tex]Z= \frac{90-95.08}{ \sqrt{\frac{9^2}{25}+\frac{12^2}{25}}} \\\\ =\frac{-5.08}{ \sqrt{\frac{81}{25}+\frac{144}{25}}}\\\\=\frac{-5.08}{ \sqrt{\frac{81+144}{25}}}\\\\=\frac{-5.08}{ \sqrt{\frac{225}{25}}}\\\\=\frac{-5.08}{ \frac{15}{5}}\\\\=\frac{-5.08}{3}\\\\= -1.693[/tex]
Calculating the conservative degrees of freedom:
[tex]DF = min (n_1 -1, n_2 - 1) = min(25-1, 25-1) = 24[/tex]
by using Excel the p-value for left tailed test and for test statistic will be [tex]-1.693[/tex] with [tex]DF = 24[/tex].
[tex]\to p-value = TDIST(1.693, 24, 1) = 0.0517\ \ \ \ i.e, \bold{0.05 < p-value < 0.10}[/tex]

If lines AB and CD are parallel, which of the following statements are true?
Check all that apply.
A. AB and CD are perpendicular
B. ABICO
O C. AB and CD intersect at a single point
D. AB || CD
E. AB and Co are skew lines
F. AB and CD are coplanar
Answer:
D
F
Step-by-step explanation:
Parallel lines are lines of equal distance apart (equidistant), that are on the same plane but they never meet
Perpendicular lines meet thus they are not parallel lines
Also, lines that intersect , meet, thus they are not parallel lines
Answer: D. AB||CD
F. AB and CD are coplaner

Parallelograms in geometry.
Answer:
x = 16
Step-by-step explanation:
In a parallelogram , consecutive angles sum to 180° , then
3x + 5 + 9x - 17 = 180
12x - 12 = 180 ( add 12 to both sides )
12x = 192 ( divide both sides by 12 )
x = 16

0.14 cm = ______ m
Conversions
Answer:
0.14 cm = 0.0014m
Step-by-step explanation:
So the phrase is:
“King Henry Died Belly Up Drinking Chocolate Milk”
The c is centimeters and meters is in between "died" and "drinking".
So 0.14 cm = 0.0014m
Because you are moving 2 to the left on the phrase so you move the decimal point 2 to the left.
***Belly up is bolded because it stands for base unit (meters, liters, gram, etc.)
I hope this makes sense!
What is the slope of the line 4x – 2y = 5?
–4
–2
2
4
Answer:
It is 2.
Step-by-step explanation:
The equation becomes -2y=-4x=5
But you divide by -2 to get y solo. So -4/-2=2.
Answer:
slope = 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
4x - 2y = 5 ( subtract 4x from both sides )
- 2y = - 4x + 5 ( divide all terms by - 2 )
y = 2x + [tex]\frac{5}{2}[/tex] ← in slope- intercept form
with slope m = 2

Answer: Annalise says that Philip will earn $320 more at First Bank than at GrandBank.
Step-by-step explanation:
Formula for Simple interest = Principal × Rate × Time
At GrandBank, the simple Interest will be:
= $2000 × 6% × 8
= $2000 × 0.06 × 8
= $960
At First Bank, the Simple interest will be:
= $2000 × 8% × 8
= $2000 × 0.08 × 8
= $1280
Based on the above, Philip will earn ($1280 - $960) = $320 more at First Bank.

Answer:
3/4
Step-by-step explanation:
Tangent is opposite/adjacent side. To get the adjacent side, use the Pythagorean Theorem:
a² + b² = c²
3² + b² = 5²
9 + b² = 25
b² = 16
√b² = √16
b = 4
tan(O) = opposite/adjacent side
tan(O) = 3/4
