10. The weight of an object on a particular scale is 125.2 lbs. The measured weight
may vary from the actual weight by at most 0.4 lbs. What is the range of actual
weights of the object?
A. 124 8 2 x 2 125.6
B. 124.8 2 x 125.6
C. 124 8 5 x 125.6
D. XS 124.8 or x 21256
Given :
The weight of an object on a particular scale is 125.2 lbs.
The actual weight by at most 0.4 lbs.
To Find :
The range of actual weights of the object.
Solution :
It is given that uncertainty in weight is 0.4 lbs.
So, minimum weight can be( 125.2 -0.4 ) = 124.8 lbs.
Maximum weight is given by ( 125.2 + 0.4 ) = 125.6 lbs.
Therefore, the range of actual weights of the object is between :
124.8 x 125.6 .
Hence, this is the required solution.

Answer:C
Step-by-step explanation:
Rural and urban students are equally
likely to get admission in a college. If 100
students get admission, then the probability
that more rural students get admission than
urban students is
Answer:
The answer is below
Step-by-step explanation:
Using binomial probability:
p = probability of a rural student getting admission = 1/2
q = probability of a rural student not getting admission = 1/2
n = number of students = 100
P(x) = [tex]C(n,x) p^xq^{(n-x)[/tex]
But [tex]p^xq^{n-x}=\frac{1}{2}^x\frac{1}{2}^{n-x}=\frac{1}{2}^{n}[/tex]
P(x > 50) = P(x = 51) + P(x = 52) + P(x = 53) + . . . + P(x = 100)
P(x > 50) = [tex]\frac{1}{2} ^{100}[C(100,51)+C(100,52)+C(100,53)+\ .\ .\ .+C(100,100)]\\[/tex]
[tex]P(x>50)=\frac{1}{2}^{100} (\frac{1}{2}( 2^{100}-C(100,50)))\\\\P(x>50)=(\frac{1}{2}^{100} *\frac{1}{2}*2^{100})- (\frac{1}{2}^{100} *\frac{1}{2}*C(100,50))\\\\P(x>50)=\frac{1}{2}[(2^{-100}*2^{100})-(\frac{1}{2}^{100} *C(100,50))]\\ \\P(x>50)=\frac{1}{2}[1-\frac{1}{2}^{100} *C(100,50)][/tex]

Answer:
x = 6, y = 8
Step-by-step explanation:
First, we need to find the scale factor from the smaller polygon to the larger polygon. To do this, we can calculate 18 / 12 which is 1.5. Therefore, we can write the following equations:
x · 1.5 = 9 → x = 6
y · 1.5 = 12 → y = 8
given f(7)=4, f'(7)=10, g(7)=-1, g'(7)=8, find the values of the following: 1. (fg)'(7) = 2. (f/g)'(7) =
By the product rule,
[tex](fg)'=f'g+fg'[/tex]
so that
[tex](fg)'(7)=f'(7)g(7)+f(7)g'(7)=10\cdot(-1)+4\cdot8=22[/tex]
By the quotient rule,
[tex]\left(\dfrac fg\right)'=\dfrac{f'g-fg'}{g^2}[/tex]
so that
[tex]\left(\dfrac fg\right)'(7)=\dfrac{f'(7)g(7)-f(7)g'(7)}{g(7)^2}=\dfrac{10\cdot(-1)-4\cdot8}{(-1)^2}=-42[/tex]
how do you multiply a fraction with a mixed number
Answer: Covert the mixed number to an improper fraction for them to be too simple fractions and multiply them.
Step-by-step explanation:
By multiply fraction by a mixed fraction you will have to rewrite the mixed number as an improper fraction.
For example ,
1 1/2 is a mixed fraction. If you convert it to improper fraction, you will get 3/2 then you multiply.
Please help I’d appreciate it so so so so much because I suck at math thank you! Ily
Answer:
the order of operations tells us how to solve a problem.
first is P for parentheses. this means you solve all the expressions within the parentheses. this ensures a simplified expression before moving on.
second is E for exponents. this means you solve all the expressions with exponents. by doing this before MDAS, you do not raise the wrong values.
third and fourth is M/D for multiplication/division. the / is between these two because these steps are interchangeable. you can multiply or divide first. the results will be the same.
this also applies to the fifth and sixth, which are A/S for addition/subtraction.

Find the particular solution to ty''-(1+t)y'+y=t^2e^t.
Complete Question
Find a particular solution to [tex]ty''-(1+t)y'+y=t^2e^t , t > 0[/tex]
[tex]y_1 = 1 + t , \ y_2 = e^t[/tex]
Answer:
The solution is [tex]y_p = -e^{2t} + t + \frac{3t^2}{2} + \frac{t^3}{2}[/tex]
Step-by-step explanation:
Now the given equation is [tex]ty''-(1+t)y'+y=t^2e^t , t > 0[/tex]
dividing through by t
We have
[tex]y'' - \frac{1 + t }{t}y' + \frac{1}{t} y = te^t \\\\ let's\ call\ it \ g(t)[/tex]
Now for the given initial value we can generate our Wronskian as follows
[tex]W(y_1 ,y_2) = | \left y_1} \atop {y_1'}} \right. \left y_2} \atop {y_2'}} \right | = | \left {(1 + t)} \atop {1}} \right. \left e^t} \atop {e^t}} \right | = (1 + t )e^t - e^t = te^t[/tex]
Now applying method of variation of parameters to obtain the particular solution
So here we assume that
[tex]y_p = v_1 y_1 + v_2 y_2[/tex]
So
[tex]v_1 = - \int\limits {\frac{y_2 (t) g(t)}{W(t)} } \, dt = - \int\limits {\frac{e^t te^t}{te^t} } = - \int\limits { e^t} } = -e^t[/tex]
And
[tex]v_2 = - \int\limits {\frac{y_1 (t) g(t)}{W(t)} } \, dt = - \int\limits {\frac{(1 + t) te^t}{te^t} } = - \int\limits (1 + t) = t + \frac{t^2}{2}[/tex]
So
[tex]y_p = -e^t * e^t + t + \frac{t^2}{2} * 1 + t[/tex]
[tex]y_p = -e^{2t} + t + \frac{3t^2}{2} + \frac{t^3}{2}[/tex]
Michael spent $18 at a local farmers’ market. Apples cost $2 each and peppers cost $3 each. Select the equation that represents the scenario. O) p = 2a + 3a + 18 O) 2a + 3a = 18p O) 2p + 3a = 18 O) 2a + 3p = 18
Answer:
its B, C and E
Step-by-step explanation:
on edge
Answer:
2a + 3p = 18
Step-by-step explanation:
The total has to equal 18 so then you have $2 and $3. Apples cost $2 so the 2 should have an a for Apples. The peppers cost $3 so the 3 should have a p for peppers. So the equation would be 2a + 3p = 18.
give an example to show that subtraction does not follow the associative rule
(6 - 2) - 1 = 4 - 1 = 3
6 - (2 - 1) = 6 - 1 = 5
The associative rule doesn't work for subtraction because you get different results when you move the parentheses.
What is the absolute value of 3.4? A) 3.4 B) -3.4 C) -34 D) -4
The absolute value of 3.4 = 3.4
The absolute value of something is always positive.
The answer is A
Answer: A. 3.4
Step-by-step explanation:
Concept:
Absolute value is the distance from a number to zero. Distance is always positive, so absolute value of any number is positive. Absolute value is often written as ( |x| ).
| -3 |=3, the distance from -3 to 0 is 3 units| 3 |=3, the distance from 3 to 0 is 3 unitsSolve:
| 3.4 |=3.4which property is illustrated?

Your checking account is in debt at $20. You use this account to make a $10 purchase. Then, you deposit $38 into the account. What is the balance of the checking account?
Answer:
$8
Step-by-step explanation:
In debt at $20 (like an overdraft) = -20
To make a $10 purchase = -10 on the account
Total debt = -20 + (-10)
= -30
You deposit $38 (this is what you added to your account.) = +38
Balance of the checking = -30 + (+38)
= $8

33 in corresponds with the 11 in side
33 in / 11 in = 3
The scale factor is 3
24 in / 3 = 8 in
x = 8 in
Answer:
Step-by-step explanation:
In similar triangles, corresponding sides will be in same ratio.
[tex]\frac{33}{11}=\frac{24}{x}[/tex]
Cross multiply,
33*x = 24 * 11
[tex]x=\frac{24 *11}{33}\\\\x=\frac{24*1}{3}\\\\x = 8 in[/tex]
Determine the range and injective of the function.
j(x) = -x - 1
Answer and Step-by-step explanation:
Solution:
Range:
Let f(x) = -x-1
Here a=0 and b= -1, x=-b/a
Put the values, we get
X= - (-1)/0 = infinity
Hence the range of the function f(x) = (-∞, ∞)
Injective:
A function is said to be injective if f(x1) = f(x2), gives x1=x2
Let f(x1) = -x1-1
f(x2) = -x2-1
f(x1) = f(x2)
