Answer:
no
Step-by-step explanation:
here, f (x)=x^3 - 4x^2 + 3x + 7
when, factor is (x + 5)
x - a =x + 5
a = -5
Reminder= f (a)
= (-5)^3 - 4 (-5)^2 + 3×(-5) + 7
= -233
Since Reminder = -233 which is not 0 .
(x + 5) is not a factor of f (x)=x3-4x2+3x+7

A person bought some cosmetics from wholesale market at the rate of Rs 360 per dozen he sells it at Rs 80 a pair find the gain percent
Answer:
33.33%
Step-by-step explanation:
We need to calculate the unit selling price and cost of each cosmetics.
If a person bought some cosmetics from wholesale market at the rate of Rs 360 per dozen., then for 1 cosmetics, we will say;
x = 1 cosmetic
since 360 = 12 cosmetic
cross multiply
12x = 360
x = 360/12
x = 30
Hence the unit cost price of the cosmetics will be Rs. 30
Similarly, if he sells it at Rs 80 a pair, then he sold one cosmetic at 80/2 = Rs. 40 (a pair is 2 cosmetics)
Selling price per unit = Rs. 40
Cost price per unit = Rs. 30
percent gain = SP-CP/CP * 100%
percent gain = 40-30/30 * 100
percent gain = 10/30 * 100
percent gain = 100/3
percent gain = 33.33%
Hence the percentage gain is 33.33%

What is the distance?Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
It is given that,500=100x
If the distance is d, velocity is v and time is t then, The formula for the distance is,
Distance = velocity × time
d=vt
The distance is in miles, v is in miles per hour and t is an hour,
miles = miles/hour × hour
The correct representation of the expression is,
If the time in an hour will be x,
An object travels 500 miles at a rate of 100 miles per hour.
Distance = velocity × time
d=vt
500=100x
Thus, the given expression is 500=100x, situations A could match this formula.

A number that is multiplied by a variable is called?
Answer:
A number that is multiplied by a variable is called a coefficient.
Select the correct answer. What is the solution for x in the equation? 29 + 15x = -x − 3
First of all, move the terms so that all those who involve [tex]x[/tex] are on one side, and all the costants are on the other:
[tex]29 + 15x = -x - 3 \iff 15x+x=-29-3[/tex]
Sum like terms:
[tex]15x+x=-29-3 \iff 16x=-32[/tex]
Divide both sides by 16:
[tex]x=-2[/tex]

Step-by-step explanation:
find the inverse with respect to addition of 9
Work Shown:
Let x be the additive inverse of 9
This means it adds to 9 to get 0
x+9 = 0 which solves to x = -9 after subtracting 9 from both sides.
So -9+9 = 0 and 9+(-9) = 0.
Answer:
-9.
Step-by-step explanation:
Because 9 + (-9) = 0.
Q.The rectangular front windshield of the bus has the length of 1.5√3 m and the width of 1.5 m . The wipers are attached to the bottom corners. If the length of each wiper is equal to the width of the windshield, find the percentage of the windshield that wipers can reach.
(Solve this task without using Trigonometry)
Answer:
Area covered by wiper=area of arc(A0D)+area of traingleAOB+area of arc(BOC)
We know AO and OB are wipers,whose lengths are 1.5
In ∆ABC
AB^2+BC^2=AC^2
(1.5√3)^2+(1.5)^2=(AC)^2
2.25×3+2.25=(AC)^2
2.25×4=AC^2
AC=3
Also AO=1.5
similarly using Pythagoras theorem in ∆OBC
we get
OC=1.5
this shows that point O is the bisector of diagonal AC
so,AO=OC
also from property of rectangle we know that, diagonal bisects each other equally
so,O will also be the bisector of diagonal BD
hence OB=OD=1.5
AC=BD (property of triangle)
AC/2=BD/2
OB=OC,hence OB=OC=OD=OA=1.5=AD=BC
Hence OAD will be an equilateral triangle
so
angle OAD=60
similarly angleOBC=60
area of sector=angle of that sector ×area of circle/360
area of arc(AOD)+arc(BOC)=60/360 ×3.14 ×1.5×1.5 +60/360 ×3.14×1.5×1.5
=2×(60/360)×1.5×1.5
area of triangleAOB=area of rectangle/4 (diagonal divides the rectangle in 4 equal parts)
area of triangle=1.5×1.5√3/4
=>1.5×2.6/4=3.90/4
=0.975 or 0.98(approx)
Area covered by wiper=.98+2×60/360 ×3.14×1.5×1.5
=.98+0.75×3.14=2.35+0.97
=2.35+.98
Percentage of area of windshield covered by wiper=3.3×100/3.9=84.61
hence percentage of area of windshield covered by wiper is 85percent(approx)

A randomized trial tested the effectiveness of diets on adults. Among 36 subjects using Diet 1, the mean weight loss after a year was 3.5 pounds with a standard deviation of 5.9 pounds. Among 36 subjects using Diet 2, the mean weight loss after a year was 0.6 pounds with a standard deviation of 4.4 pounds. Construct a 95% confidence interval estimate of the difference between the population means, assuming the population standard deviations are equal.
Answer:
The 95% confidence interval is
[tex] 0.45 < \mu_1 - \mu_2 < 5.35 [/tex]
Step-by-step explanation:
From the question we are told that
The first sample size is [tex]n_1 = 36[/tex]
The first sample mean is [tex]\= x_1 = 3.5[/tex]
The first standard deviation is [tex]\sigma_1 = 5.9 \ pounds[/tex]
The second sample size is [tex]n_2 = 36[/tex]
The second sample mean is [tex]\= x_2 = 0.6[/tex]
The second standard deviation is [tex]\sigma = 4.4[/tex]
Generally the degree of freedom is mathematically represented as
[tex]df = \frac{ [ \frac{s_1^2 }{n_1 } + \frac{s_2^2 }{n_2} ]^2 }{ \frac{1}{(n_1 - 1 )} [ \frac{s_1^2}{n_1} ]^2 + \frac{1}{(n_2 - 1 )} [ \frac{s_2^2}{n_2} ]^2 }[/tex]
=> [tex]df = \frac{ [ \frac{5.9^2 }{34 } + \frac{4.4^2 }{34} ]^2 }{ \frac{1}{(34 - 1 )} [ \frac{5.9^2}{34} ]^2 + \frac{1}{(34- 1 )} [ \frac{4.4^2}{ 34} ]^2 }[/tex]
=> [tex]df =63[/tex]
Generally the standard error is mathematically represented as
[tex]SE = \sqrt{ \frac{s_1 ^2 }{n_1} + \frac{s_2^2 }{ n_2 } }[/tex]
=> [tex]SE = \sqrt{ \frac{ 5.9 ^2 }{ 36 } + \frac{ 4.4^2 }{36} }[/tex]
=> [tex]SE = 1.227[/tex]
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the t distribution table the critical value of at a degree of freedom of is
[tex]t_{\frac{\alpha }{2}, 63 } = 1.998 [/tex]
Generally the margin of error is mathematically represented as
[tex]E = t_{\frac{\alpha }{2}, 63 } * SE[/tex]
=> [tex]E = 1.998 * 1.227[/tex]
=> [tex]E = 2.45[/tex]
Generally 95% confidence interval is mathematically represented as
[tex](\= x_1 - \x_2) -E < \mu <(\= x_1 - \x_2) + E[/tex]
=> [tex](3.5 - 0.6) - 2.45 < \mu_1 - \mu_2 < ( 3.5 - 0.6) + 2.45 [/tex]
=> [tex] 0.45 < \mu_1 - \mu_2 < 5.35 [/tex]

The forces exerted on an object are shown.
A box has an arrow pointing right labeled 6 N and an arrow pointing left labeled F.
If the object moves right, which of the following is a possible value of F?
Answer:
The possible value of F must be 5N.
Step-by-step explanation:
A vector quantity is a quantity that comprises of both magnitude and direction. And an example of a vector quantity is force.
In the given question, the pointing arrows are two forces in action, pushing the box in opposite directions.
If the values of both forces pointing left and right are equal, the box would not move. This implies that the two forces are balanced, so the box would be at a state of dynamic equilibrium.
If the box moves to the right, it implies that the force F is less than that pointing right i.e 6N > F.
Therefore, the possible value of F is less than 6N. Thus, F = 5N.
The letters in the word SANTA CLAUS are printed on identical index cards with one letter per card. The ten cards are then placed in a hat, and one card is randomly chosen (without looking) from the hat. The chance process we are interested in is what letter is on the selected card.
The missing part:
Make a model of probability showing the set of outcome and the probability value of each outcome.
Answer:
Step-by-step explanation:
From the given information:
a) From the word SANTA CLAUS, outcomes are all distinct letters.
This implies that the outcomes are S, A, N, T, C, L, U, S
For S, N, T, C, L, U, S letters, each of them is repeated once.
Thus, their respective probability = [tex]\dfrac{1}{10}[/tex]
A is repeated thrice, so probability for A = [tex]\dfrac{3}{10 }[/tex]
Using the probability distribution table; we have the following.
outcome S A N T C L U S
probability [tex]\dfrac{1}{10}[/tex] [tex]\dfrac{3}{10 }[/tex] [tex]\dfrac{1}{10}[/tex] [tex]\dfrac{1}{10}[/tex] [tex]\dfrac{1}{10}[/tex] [tex]\dfrac{1}{10}[/tex] [tex]\dfrac{1}{10}[/tex] [tex]\dfrac{1}{10}[/tex]
Find the slope of the line.

(a, 8)
(4, b)
(2, 2)
Answer:
2
Step-by-step explanation:
Slope of the line can be found using the two points, (2, 2) and (6, 10):
[tex] Slope (m) = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Let,
[tex] (2, 2) = (x_1, y_1) [/tex]
[tex] (6, 10) = (x_2, y_2) [/tex]
[tex] slope (m) = \frac{10 - 2}{6 - 2} [/tex]
[tex] Slope (m) = \frac{8}{4} = 2 [/tex]
