There are 16 squares and 20 triangles. What is the simplest ratio of squares to total shapes?
Answer:
1:6
Step-by-step explanation:
There are 20 triangles and four squares, so we know the first part of the ratio is 4. The total number of shapes is 24, so we get 4:24, and if we simplify, we then get 1:6.
Hope this helps!
There is a total of 16 squares, then the ratio of squares to total shapes is 4:9.
What is an arithmetic operation?The four fundamental operations of arithmetic are addition, subtract, multiply, and division of two or more numbers. Included in them is the study of integers, especially the order of operations, which is important for all other aspects of mathematics, notably algebra, information management, and geometry.
As per the given information provided by the question is,
Total number of squares = 16
Total number of shapes = 16 + 20 = 36
Ratio between squares and total shapes,
= 16 : 36
= 4 : 9.

A ball is dropped from a height of 100 cm. The rebound heights to the nearest centimeter are 60, 36, 22, .... What is the total distance the ball will travel both up an down?
Answer:
400 cm
Step-by-step explanation:
Given that:
Initial height at which ball was dropped = 100m
Rebound heights to the nearest cm = 60, 36, 22...
First we find the rebound percentage x;
x% * 100m = 60
100x % = 60
x = 60%
Hemce, we need to calculate the rebound velocities which aren't given:
0.6 * 22 = 13.2 = 13cm
0.6 * 13 = 7.8 = 8cm
0.6 * 8 = 4.8 = 5cm
0.6 * 5 = 3cm
0. 6 * 3 = 1.8 = 2 cm
0.6 * 2 = 1.2 = 1cm
The total distance the ball travels UP and DOWN :
(100 + 2(60) + 2(36) + 2(22) + 2(13) + 2(8) + 2(5) + 2(3) + 2(2) + 2(1))
= 400 cm

6. In case of short
circuit............current will flow in
that circuit. *
Answer:
As suggested in the name itself:
a short circuit makes the circuit 'short' which causes the resistance of the circuit to be close to none
When the resistance is decreased, the amount of current flowing in the circuit increases (ohm's law: R ∝ 1/ I)
Therefore, in case of a short-circuit. More current will flow in the circuit

What was Bear B's average speed in
m/min? No units required for answer.
Given:
Graph of positions of Bear A and Bear B.
To find:
The average speed of Bear B in m/min.
Solution:
From the graph it is clear that initial point of graph of Bear B is (0,100) and the end point is (60,2800).
The average speed of Bear B is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{2800-100}{60-0}[/tex]
[tex]m=\dfrac{2700}{60}[/tex]
[tex]m=45[/tex]
Therefore, the average speed of Bear B is 45 m/min.

Compute the estimated regression's prediction for the average score of students given 98, 129, or 159 minutes to complete the exam.
Given 98 minutes, the estimated regression's prediction for the average score of students is 91.94 .
Given 129 minutes, the estimated regression's prediction for the average score of students is 108.37
Given 159 minutes, the estimated regression's prediction for the average score of students is 124.27 (Round your responses to two decimal places.)
Compute the estimated gain in score for a student who is given an additional 32 minutes on the exam.
The estimated gain in score for a student who is given an additional 32 minutes on the exam is (Round your response to two decimal places.)
Answer:
The estimated gain in score for a student who is given an additional 32 minutes on the exam is 16.96
Step-by-step explanation:
The estimated regression prediction is given by:
[tex]\hat{y}=40+0.53x[/tex]
Where x denotes the time
y denotes the average score
A)
Substitute x = 98
[tex]\hat{y}=40+0.53(98) = 91.94[/tex]
B)
Substitute x = 129
[tex]\hat{y}=40+0.53(129) = 108.37[/tex]
C)
Substitute x = 159
[tex]\hat{y}=40+0.53(159) = 124.27[/tex]
D)the estimated gain in score for a student who is given an additional 32 minutes on the exam.
[tex]\hat{y}=40+0.53(x+32)=40+0.53x+9.57=y+16.96[/tex]
So, the estimated gain in score for a student who is given an additional 32 minutes on the exam is 16.96
A national standard requires that public bridges over feet in length must be inspected and rated every 2 years. The rating scale ranges from 0 (poorest rating) to 9 (highest rating). A group of engineers used a probabilistic model to forecast the inspection ratings of all major bridges in a city. For the year 2020, the engineers forecast that % of all major bridges in that city will have ratings of 4 or below. Complete parts a and b. a. Use the forecast to find the probability that in a random sample of major bridges in the city, at least 3 will have an inspection rating of 4 or below in 2020. P(x3) nothing (Round to five decimal places as needed.)
Answer:
The answer is below
Step-by-step explanation:
A national standard requires that public bridges over 20 feet in length must be inspected and rated every 2 years. The rating scale ranges from 0 (poorest rating) to 9 (highest rating). A group of engineers used a probabilistic model to forecast the inspection ratings of all major bridges in a city. For the year 2020, the engineers forecast that 4%of all major bridges in that city will have ratings of 4 or below.
a. Use the forecast to find the probability that in a random sample of major bridges in the city, at least 3 will have an inspection rating of 4 or below in 2020.
Answer:
This problem is a probability binomial distribution and it can be solved using the formula:
[tex]P(X=x)=C(n,x)p^xq^{n-x}\\\\q=1-p,C(n,x)=\frac{n!}{x!(n-x)!}[/tex]
Hence the solution to the problem is given as:
P(x ≥ 3) = 1 - P(x < 3) = 1 - [ P(x=0) + P(x=1) + P(x = 2)]
Given that p = 4% = 0.04, q = 1 - p = 1 - 0.04 = 0.96, n = 10. Hence:
[tex]P(x=0)=C(10,0)*0.04^{0}*(0.96)^{10-0}=0.6648\\\\P(x=1)=C(10,1)*0.04^{1}*(0.96)^{10-1}=0.277\\\\P(x=2)=C(10,2)*0.04^{2}*(0.96)^{10-2}=0.0519\\\\P(x\geq 3)=1-[0.6648+0.277+0.0519]=0.0063[/tex]

The heart rates in beats per minute for runners who walk briskly on a treadmill for 6 minutes follow a Normal distribution with a mean of 104 and standard deviation of 12.5. What percent of the runners have heart rates above 140?
Answer:
0.2%
Step-by-step explanation:
We apply the z score formula.
This is given as:
Z score = x - μ/σ
x = Raw score = 140
μ = Population mean = 104
σ = Standard deviation = 12.5
z = 140 - 104/12.5
z = 2.88
Probability value from Z-Table:
P(x<140) = 0.99801
P(x>140) = 1 - P(x<140)
= 1 - 0.99801
= 0.0019884
Approximately = 0.0020
Converting to percent = 0.2%
Therefore, percent of the runners have heart rates above 140 is 0.2%
