Answer:
x = 5 , y = -1
Step-by-step explanation:
Solve the following system:
{4 y + x = 1 | (equation 1)
5 y + 3 x = 10 | (equation 2)
Swap equation 1 with equation 2:
{3 x + 5 y = 10 | (equation 1)
x + 4 y = 1 | (equation 2)
Subtract 1/3 × (equation 1) from equation 2:
{3 x + 5 y = 10 | (equation 1)
0 x+(7 y)/3 = -7/3 | (equation 2)
Multiply equation 2 by 3/7:
{3 x + 5 y = 10 | (equation 1)
0 x+y = -1 | (equation 2)
Subtract 5 × (equation 2) from equation 1:
{3 x+0 y = 15 | (equation 1)
0 x+y = -1 | (equation 2)
Divide equation 1 by 3:
{x+0 y = 5 | (equation 1)
0 x+y = -1 | (equation 2)
Collect results:
Answer: {x = 5 , y = -1

Michael has a bag of marbles. The frequency of selecting each color is recorded in the table below. Outcome Frequency Green 4 Black 6 Orange 5 Based on the given frequency, determine the experimental probability of selecting a black marble. 0.27 0.33 0.40 0.60
help asap if answer is correct and provided explanation i will give brainiest.
Reason:
6 black out of 4+6+5 = 15 total
6/15 = 0.40 is the experimental probability of selecting black.
Side note: The term "empirical probability" is the same as "experimental probability".
The experimental probability of selecting a black marble will be 0.40. The correct option is C.
What is probability?Probability is a number that indicates the likelihood of an event occurring. Probability is defined as the ratio of favourable outcomes to all outcomes.
Probability = Number of favourable outcomes / Number of samples
Given that Michael has a bag of marbles. The frequency of selecting each colour is recorded in the table below. Outcome Frequency Green 4 Black 6 Orange 5.
Number of favourable outcomes = 6
Number of samples = 4+6+5 = 15
Probability = Number of favourable outcomes / Number of samples
Probability = 6 / 15
Probability = 0.40
Therefore, the probability will be 0.40.

How can I find the cube root of 64?
Answer:
4
Step-by-step explanation:
The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.
The cube root of 64 is 4.
Before solving the question, let's understand the concept of cube root.
The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.
The cube root is denoted by ∛
Now, we will find the cube root of 64.
Firstly, we have to find factor 64.
64 = 2 × 2 × 2 × 2 × 2 × 2.
64 = ∛4³
64 = 4
Therefore, the cube root of 64 is 4.

Make a perspective drawing of the following figure by using the top, side and front
views as shown. (5 points)
Answer:
The shape really appears in my mind as exactly as the side shows. From the top, it would appear to be a square, first of all because no shadows, and because the slant is facing up. From the front, it would be the exact same thing as I just described. Only from the side can you see that it's a square, wedge triangle.

Could any one say for me the volume and the surface for "Pyramid, Cone and Sphere"
Plz help!!
Who will answer will be the *"Brainliest"*
Thank u
Answer:
Pyramid: In fact, the volume of any pyramid is one-third the area of the base times the height. Finding the surface area of a pyramid is done by first finding the area of the base and the area of each lateral face. … Lastly, the surface area of a pyramid is the sum of the area of the base and the lateral area!
Cone: a volume of 4 3 π r 3 \frac{4}{3} \pi r^3 34πr3 and a surface area of 4 π r 2 4 \pi r^2 4πr2.
Sphere: A cone is essentially a pyramid with a circular base. The volume of a pyramid is given by Vpyramid=Abase⋅h3. Since the area of the base of a cone is πr2, the formula for the volume of a cone is Vcone=πr2h3.

Answer:
12) x= 29 ; (4+5x) = 149° ; (x+2) = 31°
15) x=29 ; (2x+1) = 59° ; (x+2) = 31°
16) x=17 ; (4+2x) = 38° ; (3x+1) = 52°
Step-by-step explanation:
So for each problem you follow the same steps.
1) See what the angles should measure up to. (#12 is 180°, and #15 & 16 is 90°
2) Write your equation. (I'm going to use #12 as an example). 4+5x+x+2=180
3) Simplify the equation. 6x+6=180
4) Solve the equation. x=29
5) Then replace each x with the 29, and solve.
6) To double-check the angles, add both angles together and they should be 180° (or whatever you decided you were solving for on step 1)

D
Answer:
D. BE
Step-by-step explanation:
You want a line segment in the given figure that is skew to segment GH.
SkewA skew segment is one that does not and cannot lie in the same plane as a given line segment. Here, segments AD, BC, EF are all parallel to segment GH, so could lie in the same plane with GH.
Segments AH and DG intersect GH, so also could lie in the same plane with GH.
Segments BE and CF do not intersect segment GH, and are not parallel to it. They are skew with respect to GH.
A segment skew to GH is BE, choice D.

Find the best measure of variability for the data and determine which player was more consistent.
Player B is the most consistent, with an IQR of 3.5.
Player B is the most consistent, with a range of 10.
Player A is the most consistent, with an IQR of 1.5.
Player A is the most consistent, with a range of 5.
Answer: Player B is the most consistent, with an IQR of 3.5.
Step-by-step explanation:
For Player A, the IQR is 2 (Q3 - Q1 = 3 - 1 = 2).
For Player B, the IQR is 3.5 (Q3 - Q1 = 5 - 1.5 = 3.5).
Therefore, Player B is more consistent, as their IQR is larger, indicating less variability in their scores.

A group of friends wants to go to the amusement park. They have no more than $160 to spend on parking and admission. Parking is $5, and tickets cost $15.50 per person, including tax. Use the drop-down menu below to write an inequality representing p, the number of people who can go to the amusement park.
Answer:
p=10 friends
Step-by-step explanation:
$160-$5=$155
$155 divided by $15.50=10
Can I have brainlist pls?
if everyone only needs one parking space altogether, the equation would be 160=15.50x+5
to solve that, you would need to move the 5 to the left and then divide the equation by 15.50
so it would look like this: (155=15.50x)/15.50
155/15.50 equals 10, so your answer would be x=10
10 friends can go :)

Answer:
75 hairs/ day = 525 hairs / week
Step-by-step explanation:
so your base question for this is 75 hairs/ day =? h/ week. how? if the dog is losing 75 hairs per day, then you would do 75 x 7 becuase there are 7 days in a week. the answer to that would give you how many hairs the dog was losing per week. (see attached image for reference)
