Emilio has 7 boxes. Each box weight 3/4 kilograms. Whatvis the total weight
Answer:
Step-by-step explanation:
(7 boxes)*(0.75 kg/box) = 9 1/3 kg
Emilio has 7 boxes. Each box weight 3/4 kilograms. What is the total weight?
____________________Solution :-Given Information :-Number of boxes Emilio has ➢ 7 boxes Weight of each box ➢ [tex]\sf \frac{3}{4}\small \: Kg [/tex] eachTo Find :-The total weight of the boxes.Concept Used :-We will simply multiply the weight of each box with the number of boxes, the product will be the total weight of all the boxes, which Emilio has.Calculation :-⇒ Weight of each box × Number of boxes = Total Weight of all the boxes
Substituting the values, We get,
⇒ [tex]\sf \frac{3}{4}\small \: Kg \times 7[/tex]
Calculating further, We get,
⇒ [tex]\sf 5.25 \: Kg [/tex]
∴ Total Weight of all the boxes is 5.25 Kg
____________________Final Answer :-The total weight of 7 boxes Emilio has is 5.25 Kg.

Answer:
(1) 36.6 feet
Step-by-step explanation:
m∡Q = 180-(90+55) = 35
sin 35°/21 = sin 90°/PQ
cross-multiply to get:
21 = sin35·PQ
21/sin 35 = PQ
PQ = 36.6
A university was interested in examining the overall effectiveness of its online statistics course, along with the effectiveness of particular aspects of the course. First, the university wanted to see whether the online course was better than a standard course. Second, the university wanted to know whether students learned best using Excel, using Minitab, or using no statistical package at all. The university randomly selected a group of 30 students and administered one of the different variants of the course (i.e., traditional or online, coupled with one of the three software options) to each student. The success of each variant was measured by the students' average improvement between a pre-test and a post-test.
i. Is this a controlled experiment or observational study?
ii. What are the explanatory variables?
A. The students mean pre-test average score.
B. Whether the course was online or traditional.
C. Whether the course was online or traditional and the statistical software used.
iii. The response variable is:
A. the students' mean post-test score.
B. the difference between the students' mean pre-test and post-test scores.
C. an evaluation of course quality provided by an independent rater.
iv. How many treatment groups are there in this study?
A. 3
B. 4
C. 5
D. 6
E. 7
Answer:
i. This is controlled experiment
ii. C. Whether the course was online or traditional and the statistical software used.
iii. B. The difference between students mean pre-test and post-test scores.
iv. D. 6
Step-by-step explanation:
This is controlled experiment because the university is observing students who take either online course or a standard course. The students have 3 different software available which they can learn. The students are observed based o pre test and post test results.

Answer:
Part 1:
y= 23
Part 2:
x=20
Step-by-step explanation:
Part 1:
cos(y) = 48/52
y=cos^-1(48/52)
y=22.619864948~23
Part 2:
48^2+x^2=52^2
x^2=2704-2304
x=sqrt(400)
x=20 or -20.
A negative length makes no sense, so x=20
Answer:
y = 23º
x = 20 cm
Step-by-step explanation:
Cos∅ = adj/hyp
cosy = 48/52
∅ = arccos48/52

What is mathematical values?A mathematical value can generally be any specific mathematical object. This is most frequently a number in elementary mathematics, such as a real number like or an integer like 42. Every integer or even other mathematical object set to a variable or constant is that object's value.
A mathematical expression's value is the outcome of a computation it describes when its variables and constants are given values. The amount that the function assumes for these argument numbers is the result of a function, assuming the value(s) provided to its argument(s). Square root of 16 is 4, square root of 8 is 2, but for an answer it would be , 4² is 16, 1² is 2, number 5 would be 64 and number 6 would be 12.
Therefore, Square root of 16 is 4, square root of 8 is 2, but for an answer it would be , 4² is 16, 1² is 2, number 5 would be 64 and number 6 would be 12.

What is the value of d to the nearest hundredth?
Answer:
The value of the d is 6.48
Step-by-step explanation:
The value of the d is 6.48, if the angle D E F is 90 degrees and angle F D E is 42 degrees and the length of D E is 7.2 and the length of E F is d.

In a survey of 554 U.S. adults, it is found that 360 favor a ban on stem cell research. Set up the null and the alternative hypotheses to test whether there is sufficient evidence that over 61% favor a ban on stem cell research. If alpha is set to 3.0%, should the null hypothesis be rejected
Answer:
The null hypothesis will be rejected
Step-by-step explanation:
The null hypothesis is that people who favour ban on stem cell research is less than or equal to 0.61
The alternate hypothesis is that people who favour ban on stem cell research is greater than 0.61
Proportion of population = 0.61
Total events = 360
Sample size = 554
Sample proportion = 360/554 = 0.649
As per test statistics –
Z = (p-p0)/sqrt {(p0 (1-p0))/n} = (0.649 -0.61)/ {(0.61 (1-0.61))/554}
= 0.039/0.021
= 1.857
P (Z<1.857) = 1- P (Z<1.857) = 1-0.9664 = 0.0336
So alpha value is 0.064.
Thus, we will reject the null hypothesis

what does y intercept mean ?
Answer: The vertical line on a graph representing the vertical coordinate points.
Answer:
In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x = 0. Hope this helps.

Which statements are true about the graph of function f?
F(x)=1n x
Please I really need help!!
Answer:
D: See attached file and explanation
Step-by-step explanation:
Notice how the function has a vertical asymptote at x=0, indicating that 0 is the minimum of the domain which is not included.
The end behavior of the function would be as x approaches infinity, y approaches infinity, which means that the correct domain would be {x|0<x<∞}.
Additionally, the function crosses the x-axis at (1,0) so that would be the x-intercept.
There is no y-intercept because x=0 is undefined for the function as we already described earlier with it being the line of the vertical asymptote.
Therefore, the correct answer is D. See the graph for reference.
Find the amount of wood trim needed to frame a circular window with a diameter of 1.75 ft. Use 3.14 for n.
Answer:
2.40 ft I believe
Step-by-step explanation:
divide diameter by two
put 3.14 time diameter divided by two and square it
A. Directions: Find the surface of the following. Round your answer to nearest
hundredths. (Use n = 3.14) Write your answer in your notebook.
1) cone with radius of 15 cm and slant height of 12 cm
2) cone with radius of 8 cm and slant height of 11 cm
3) sphere with radius of 3.2 cm
4) sphere with diameter of 6 cm
Answer:
1. S.A of a cone = 565.56 cm².
2. S.A of a cone = 276.496 cm².
3. S.A of a sphere = 128.696 cm².
4. S.A of a sphere = 113.112 cm².
Step-by-step explanation:
Given the following data;
1. Radius, r = 15cm
Slant height, l = 12cm
Mathematically, the surface area of a cone is given by the formula;
Surface area of a cone = πrl
Substituting into the formula, we have;
S.A of a cone = 3.142 * 15 * 12
S.A of a cone = 3.142 * 180
S.A of a cone = 565.56 cm²
2. Radius, r = 8cm
Slant height, l = 11cm
Surface area of a cone = πrl
S.A of a cone = 3.142 * 8 * 11
S.A of a cone = 3.142 * 88
S.A of a cone = 276.496 cm²
3. Radius, r = 3.2 cm
Mathematically, the surface area of a sphere is given by the formula;
Surface area of a sphere = 4πr²
Substituting into the formula, we have;
S.A of a sphere = 4 * 3.142 * 3.2²
S.A of a sphere = 4 * 3.142 * 10.24
S.A of a sphere = 40.96 * 3.142
S.A of a sphere = 128.696 cm²
4. Diameter, d = 6cm
Radius, r = diameter/2 = 6/2 = 3 cm
Surface area of a sphere = 4πr²
S.A of a sphere = 4 * 3.142 * 3²
S.A of a sphere = 4 * 3.142 * 9
S.A of a sphere = 36 * 3.142
S.A of a sphere = 113.112 cm²

Evaluate: 9m+7n if m=-7 and n=4
Answer: look at the picture
Step-by-step explanation: Hope this help :D
For m = -7, n = 4, 9m+7n = -35
What is evaluating an algebraic expression?
"To solve or evaluate an expression is nothing but substitute the given value of the variable in the expression and then simplify the expression using the order of mathematical operations."
Given expression:9m+7n
We need to solve this expression for m = -7 and n = 4.
Substituting m = -7, n=4 in given expression,
⇒ 9m+7n
⇒ 9(-7) + 7(4)
⇒ -63 + 28
⇒ -35
Therefore, for m = -7, n = 4, 9m+7n = -35
