Answer:
$340 ≤ S2 ≤ $375
$410 ≤ S1 ≤ $445
Donde S1 es el sueldo del trabajador que gana más.
Step-by-step explanation:
Definamos las variables:
S1 = salario del trabajador 1
S2 = salario del trabajador 2
Y supongamos que el trabajador 1 gana $70 más que el trabajador 2.
Entonces tenemos la relación:
S1 = S2 + $70
Y sabemos que la suma de sus salarios esta entre $750 y $820
Entonces:
$750 ≤ S1 + S2 ≤ $820
Si reemplazamos S1 por lo que tenemos arriba, nos da:
$750 ≤ (S2 + $70) + S2 ≤ $820
$750 ≤ $70 + 2*S2 ≤ $820
Ahora podemos restar $70 en las tres partes:
$750 - $70 ≤ $70 + 2*S2 - $70 ≤ $820 - $70
$680 ≤ 2*S2 ≤ $750
Ahora podemos dividir las tres partes por 2:
$680/2 ≤ 2*S2/2 ≤ $750/2
$340 ≤ S2 ≤ $375
ahora tenemos el rango de S2.
Y sabemos que S1 = S2 + $70
entonces:
S2 = S1 - $70
reemplazando obtenemos:
$340 ≤ S1 - $70 ≤ $375
Sumamos $70 en las 3 partes:
$340 + $70 ≤ S1 - $70 + $70 ≤ $375 + $70
$410 ≤ S1 ≤ $445
Que es el rango de S1.
Entonces:
$340 ≤ S2 ≤ $375
$410 ≤ S1 ≤ $445
Son los rangos de los sueldos de cada uno.

The base of this prism is triangle.
Answer:
Step-by-step explanation:
Remark
It's a right angle triangle. I feel for 17 points, I should be telling you more.
Surface Area
The two faces are triangles. Their area = 1.5 * 2 / 2= 1.5
What I have you is the area of 1 triangle. There are 2 so 2*2.5 = 3
======================
The height of the prism = 10 meters.
The Area of that face = L * w = 10 * 2.5
Area of that face = 25 m^2
Area of the rectangle containing 1.5 as the width = 1.5 * 10 = 15
Area of the rectangle containing 2 as the width = 2 * 10 = 20
The Total Surface Area = 20 + 15 + 25 + 5 = 65 m^2
Volume
Volume = Area of 1 triangle * height
Volume = 1.5 * 10 = 15 m^3

The measure of one angle of a right triangle is 42∘ more than the measure of the smallest angle. Find the measures of all three angles.
Answer:
Step-by-step explanation:
A ≤ B ≤ C
C = 90°
B = A+42°
A+B = 90°
A+(A+42) = 90°
A = 24°
B = A+42° = 66°
24, 66, 90 are the measure of all three angles of the right angle triangle
What is right-angle triangle?A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse.
Given, The measure of one angle of a right triangle is 42∘ more than the measure of the smallest angle.
Let "x" be the smallest angle in a right angle triangle.
So, biggest angle in the triangle will be x +42
Since, sum of the all the angles in a triangle = 180
x + x+ 42 +90 = 180
2x + 42 = 90
2x = 48
x = 24
Measure of the smallest triangle =x = 24
Measure of the biggest angle = 24 + 42
Measure of the biggest angle = 66
therefore, The measure of all three angles of the right angle triangle are 24, 66, 90.

2g + h =2
g -h= -5
find g and h step by step explanation
Answer:
Step-by-step explanation:
2g + h = 2 --------------(I)
g - h = -5------------(II)
g = -5 + h
Plugin g = -5 + h in equation (I)
2(-5 + h) + h = 2 {Distributive property:a(b+c) = a*b +a*c}
(-5)*2 + h *2 + h= 2
-10 + 2h + h = 2
3h = 2 + 10
3h = 12
h = 12/3
h = 4
Substitute h= 6 in equation (I)
2g + 4 = 2
2g = 2 - 4
2g = -2
g = -2/2
g = -1

In Ms. Perron’s class, 60% of the students are boys. There are 26 students in the class. What is the total number of boys in Ms. Perron’s class?
Help :'/
Answer:
Let the no. of students be X.
Boys = 60% of X .
So Boys = (60/100)*X.
So left 40% of students are girls and it is given they are 14.
So total students X= total boys + total girls.
X = (60/100)*X+14.
(40/100)*X = 14.
X = (14*100)/40.
X = 35.
X - (60/100)*X = 14.

A library association plans to take an SRS of 150150150 adults from the population of adults in the US to see what proportion of adults sampled believe that public libraries help them learn new things. Suppose that 76\vv, percent of adults in the US believe that public libraries help them learn new things. What are the mean and standard deviation of the sampling distribution of the proportion of US adults who believe that public libraries help them learn new things
Answer:
Mean: =0.76
SD= (squarerootof) 0.76(0.24)/150
Step-by-step explanation:
The mean of the sampling distribution is 0.76 and the standard deviation is approximately 0.00344.
What is the standard deviation?The standard deviation mathematical and statistical analysis tool used to explain the diversity of treatments or values around the Mean is the standard deviation, which is also known as the square root of variance.
The mean of the sampling distribution of the proportion of US adults who believe that public libraries help them learn new things is equal to the proportion of all adults in the US who believe that public libraries help them learn new things, which is 76% = 0.76.
The standard deviation of the sampling distribution is equal to the standard error of the proportion, which can be calculated as follows:
standard error = √((76% × 24%) / 150)
= √((0.76 × 0.24) / 150)
= √(0.01824 / 150)
= √(0.0000121)
= 0.00344
Therefore, the standard deviation is approximately 0.00344.
