What is a deduction ?
Solve the system of equations.
-5x + 4y = 3
X = 2y - 15
Answer:
x=9
y=12
Step-by-step explanation:
. Substitute the given value of x into the equation so... -5(2y-15)+4y=3
. y=12
. Substitute the given value of y into the equation x=2y-15 so... x=2 x 12-5
. x=9
.The possible solution of the system is the ordered pair (x,y) so... (x,y)=(9,12)
In the figure below, angle y and angle x form vertical angles. Angle x forms a straight line with the 50° and the 40° angle.
Write and solve an equation to determine the measure of angle y.
Answer:
the answer is 60° I think
Can someone help me
Answer:
3 cm
Step-by-step explanation:
First, we have to understand what happens if two shapes are similar. When two shapes are similar, the angles are equal in both. This means the sides will be in the same ratio from one shape to another.
[tex]\frac{7.2}{t}=\frac{9.6}{4}[/tex]
Using the equation above, we can find t. We use cross multiplication (ad = bc)
7.2 * 4 = 9.6t
9.6t = 28.8
t = 3 cm

You want to estimate the mean number of sentences in a magazine advertisement.How many magazines advertisements must be included in the sample if you want to be 95% confident that the sample mean is within one sentence of the population mean
Complete question:
You want to estimate the mean number of sentences in a magazineadvertisement. How many magazine advertisements must beincluded in the sample if you want to be 95% confident that thesample mean is within 1 sentence of the population mean ? (sigma =5)
Answer:
96
Step-by-step explanation:
We have level of confidence = 95%
Alpha = 1-0.95
= 0.05
Alpha/2 = 0.025
Z-alpha/2 = 1.96
E = margin of error = 1
For this question the formula to derthe sample size is given as:
n = [(Za/2 x sigma)/E]²
n = (1.96 x 5/1)²
n = 9.8²
= 96.04
So 96 magazines advertisement must be included in the sample to be 95% confident.
a=3, b=15, c=Pythagorean
theorem
Answer:
Step-by-step explanation: Given a=3 and b=15,
c = 3√26 = 15.297058540778
∠α = 11.31° = 11°18'36" = 0.1974 rad
∠β = 78.69° = 78°41'24" = 1.3734 rad

the property tax in a certain country varies directly as assessed valuation. If a tax of $1,590 is charged on a single-family home assessed at $81,000, determine the property tax on an apartment complex assessed at $237,600.
Answer: $4,664
Step-by-step explanation:
Direct Variation can be set up as a proportion:
[tex]\dfrac{\text{Property Tax}}{\text{Assessed Valuation}}:\dfrac{1590}{81,000}=\dfrac{x}{237,600}[/tex]
Cross Multiply: x = 4664

. The length of the long-distance calls made by the employees of a company followed a normal distribution with a mean of 6.5 minutes and a standard deviation of 2 minutes. a. What is the probability that a call lasts less than 4 minutes
Answer:
The probability that a call lasts less than 4 minutes
P(X<4) = P(Z<-1.25) = 0.1056
Step-by-step explanation:
Step(i):-
Given mean of the population = 6.5 minutes
Given standard deviation of the Population = 2 minutes
Let 'X' be the random variable in normal distribution
Given X = 4
[tex]Z= \frac{x-mean}{S.D} = \frac{4-6.5}{2} = -1.25[/tex]
Step(ii):-
The probability that a call lasts less than 4 minutes
P(X<4) = P(Z<-1.25)
= 1-P(z>1.25)
= 1 - ( 0.5 +A(1.25)
= 1-0.5 - A(1.25)
= 0.5 - 0.3944 ( from normal table)
= 0.1056
Final answer:-
The probability that a call lasts less than 4 minutes
P(X<4) = P(Z<-1.25) = 0.1056
