Answer:
93
Step-by-step explanation:
Key :
A1 = Algebra 1
A2 = Algebra 2
Alright so basically lets first look at the info they gave us :
We have 5 more than twice as many students taking A1 than we do A2.
We have 44 students taking A2.
And we need to find the least amount of students that could be taking A1.
So we need to take the amount of students taking A2 (44) and double it to find the amount taking A1.
So we can do 44 x 2 = 88 to get this.
But the problem also states there is 5 more then twice the number of students taking A2.
So we have that 88 but now we just need to add 5 to make up for them telling us that in the problem.
So :
88 + 5 = 93
Our final answer and least amount of students taking A1 is 93 students.
Answer:
93 students
Step-by-step explanation:
44 x 2 = 88
88 + 5 = 93
Ammeters produced by a manufacturer are marketed under the specification that the standard deviation of gauge readings is no larger than 0.2 amp. One of these ammeters was used to make ten independent readings on a test circuit with constant current. The sample variance S 2 of these ten measurements is 0.0653 and it is reasonable to assume that the readings are normally distributed. Find the approximate probability that the sample variance will exceed 0.0653 if the true population variance is 0.04
Answer:
0.101
Step-by-step explanation:
Given that :
Standard deviation, s = 0.2
Sample variance, s² = 0.0653
Sample size, n = 10
Population variance = σ² = 0.04
We use the Chi square distribution :
(n - 1)s² / σ²
For P(s² ≥ 0.065)
(n - 1)s² / σ² = (10 - 1)*0.0653 / 0.04
(n - 1)s² / σ² = 0.585 / 0.04 = 14.625
P(s² ≥ 14.625) = 0.101 ( chi squee calculator).

What is the value of r of the geometric series?
Sigma-Summation Underscript n = 1 Overscript 3 EndScripts 1.3 (0.8) Superscript n minus 1
Answer:
A) 0.8
Step-by-step explanation:
0.8 on edge.
The value of r of the geometric series is 4/5.
What is geometric series?
The geometric series defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.
The nth term of a geometric progression is expressed as
Tₙ = arⁿ⁻¹
Where a is the first term, r is the common ratio
Given the formula for the geometric series expressed as
[tex]_3\\\sum{1.3(0.8)^n^-^1}\\n=1[/tex]
Comparing both equations
rⁿ⁻¹ = (0.8)ⁿ⁻¹
r = 0.8
r = 8/10
r = 4/5
Hence, the common ratio is 4/5.

Dakota has 4/10 kg of clay he divided the clay to make eight equal parts how many grams of clay are in each pot
Answer:
Dakota must put 50 grams of clay in each pot to be able to divide the clay into 8 equal parts.
Step-by-step explanation:
Given that Dakota has 4/10 kg of clay and I divided the clay to make eight equal pots, to determine how many grams of clay are in each pot the following calculation must be performed:
4/10 kg = 0.4 kg = 400 grams
400/8 = X
50 = X
Thus, Dakota must put 50 grams of clay in each pot to be able to divide the clay into 8 equal parts.

14 masons can build 2 houses in 6 months. Find how many houses 21 masons can build in the same duration.
Answer:
3 houses
Step-by-step explanation:
2 houses = 14 masons
1 house = 14 ÷ 2 = 7
Find out what 21 ÷ 7 is, which is 3.
So 21 masons can build 3 houses in 6 months.
Grocery store scales are occasionally checked by inspection agencies for their accuracy in reporting the weights of purchased merchandise. Scales are allowed to operate as long as the percent error of their reported weights is within 0.5% of the actual weight measured. If you wanted to purchase 15.0 pounds of flour, what range of weights is the scale allowed to report in order to be compliant with local inspection agency regulations.
Answer:
The range of weights in the scale allowed to report in order to be compliant with local inspection agency regulations is between 14.925 pounds and 15.075 pounds.
Step-by-step explanation:
The weights should be within 0.5% of the actual weight measured.
15.0 pounds
0.005*15 = 0.075
Tolerance of 0.075 pounds
15 - 0.075 = 14.925 pounds
15 + 0.075 = 15.075 pounds
The range of weights in the scale allowed to report in order to be compliant with local inspection agency regulations is between 14.925 pounds and 15.075 pounds.

Another word for x-intercepts?
Answer:
X-intercepts are also called zeros, roots, solutions, or solution sets.
Another word for "x-intercepts" is "roots" or "zeros." These terms are commonly used in the context of mathematics, particularly when dealing with functions or equations.
X-intercepts, roots, or zeros of a function are the values of the independent variable (usually denoted as "x") for which the function evaluates to zero.
In other words, they are the points on the graph of the function where it intersects the x-axis, hence the name "x-intercepts."
Mathematically, for a function f(x), the x-intercepts are the solutions to the equation f(x) = 0.
Finding the x-intercepts of a function is essential in graphing, solving equations, and understanding the behavior of the function.
These points represent the locations where the function crosses or touches the x-axis, indicating where the dependent variable (usually denoted as "y") is equal to zero.

Larger number:
Smaller number:
Answer:
larger number: 34
smaller number: 20
Step-by-step explanation:
54= y+y-14
54= 2y - 14
54+14 = 2y
68 = 2y
68/2 = 2y/2
34 = y, the larger number
y - 14 = 34-14 = 20 the smaller number

Answer:
26.75 square units
Step-by-step explanation:
Above the dashed horizontal line(s) is a triangle with base 9 and height 3.5. Its area is ...
A = (1/2)bh
A = (1/2)(9)(3.5) = 15.75 . . . . square units
__
Below the dashed horizontal line(s) is a trapezoid with bases 9 and 2, and height 2. Its area is ...
A = (1/2)(b1 +b2)h
A = (1/2)(9 +2)(2) = 11 . . . . square units
The sum of these areas is the area of the shape:
total area = 15.75 +11 = 26.75 . . . . square units
