The ∠3+ ∠1 = 90°. in the given figure are the same just using the properties of Vertically angles.
What is Vertically opposed angles?
Two lines intersecting at a point create vertical angles. Every time they are on an equal footing. Alternatively stated, four angles are created anytime two lines cross or intersect. Two opposed angles are equal and are referred to as vertical angles, as we can see. Due to their position opposite one another, they are also known as "Vertically opposed angles."
Angles that are vertically opposed to one another at a certain vertex are formed by two straight lines intersecting. The equality of the vertically opposed angles has been established.
∠1 and ∠2 are vertical angles, which means ,
∠1 =∠2
Given in the question is ∠3+ ∠2 = 90
As both ∠1 and ∠2 are the same so we can write ∠3+ ∠1 = 90°.
Hence, The ∠3+ ∠1 = 90°. in the given figure are same.

(report answer as a decimal value accurate to four decimal places.) p(accept shipment)
Answers
0.9660 is the probability that this whole shipment will be accepted if a particular shipment of thousands of ibuprofen tablets actually has a 15% rate of defects
What is probability ?Probability turned into added into arithmetic to are expecting the possibility of an occasion occurring. Probability essentially approach how in all likelihood it's miles that some thing will happen. This is the fundamental principle of possibility and is likewise utilized in possibility distributions to examine feasible consequences of random experiments.
CalculationIf the number of tablets in a shipment is sufficiently large, we can consider the testing procedure you describe (selecting a random sample of 29 ibuprofen tablets and counting the number of defective tablets in the sample) to be a binomial probability experiment.
Let X = (Number of defective ibuprofen tablets in a random sample of 29 tablets.) Then we may reasonably assume that X follows a binomial distribution. For each "trial" (that is, each tablet selected), there are two possible outcomes, "success" (the tablet is defective), or "failure" (the tablet is not defective). Note that the word success as used in the binomial distribution does not carry the connotation of being a "good" outcome. A "success" is simply the outcome you are interested in counting, which in this case is the number of defectives in the sample. The important parameters for a binomial distribution are n (the number of trials) and p (the probability of success on any one trial.) For this situation, we have p = .01 (since we are told 1% of the tablets in the shipment are defective) and n = 29. The general formula for the binomial distribution is
P(x) = nCx·px·(1 - p)n-x
where x is the number of successes in n trials (In this problem, x is the number of defectives in a random sample of 29 tablets.) The symbol nCx is the "number of combinations of n things taken x at a time". This is the number ways of choosing x distinct objects from a set of n objects, without regard to order. It is given by
nCx = n!/[x!·(n-x)!]
where ! is the factorial symbol.
We want to find the probability that the shipment is accepted. We are told that a shipment will be accepted if at most one tablet doesn't meet the required specifications. That is, the number of defectives must be less than or equal to one.
P(Shipment accepted) = P(X ≤ 1). (In this case, X ≤ 1 if and only if X=0 or X=1)= P(0) + P(1).
So we calculate P(0) (the probability of 0 defective tablets in the shipment), and P(1) (the probability of 1 defective.) Using the formula for the binomial distribution, we have
P(0) = 29C0·(.01)0·(1 - .01)29 - 0.
But 29C0 = 1, so
P(0) = 1·(.01)0·(.99)29 ≅ .74717
Also,
P(1) = 29C1·(.01)1·(1 - .01)29 - 1.
Calculating 29C1, we have
29C1 = 29!/[1!·(29-1)!] = 29, so
P(1) = 29·(.01)1·(99)28
P(1) ≅ .21887
Finally, then, we have
P(Shipment accepted) ≅ .74717 + .21887 ≅ .9660 (to 4 decimal places.)

Therefore,
number of boys = 3 / 5 × 9 = 27 / 5 = 5.4

katie has £1200. she gives 1/3 of the money to her sister. Then katie give 1/4 of the remaining money to her brother. how much money does katie have left?
Answers
Answer:
£600
Step-by-step explanation:
Katie gives 1/3 of the money to her sister.
1/3 of 1200 is 400, because 1200 divided by 3 is 400. So she gives 400 to her sister, which means she has 1200-400= 800 left.
When she gives 1/4 of the remaining to her brother, that means that we need to figure out how much 1/4 of 800 is. 800 divided by 4 is 200. So Katie gives 200 to her brother.
800 that she has remaining minus the 200 she gives to her brother leaves her with 800-200 = 600

1012If the regular price of the pair of glasses was $72 how much did Gabriela pay wit the discount
Answers
The amount Gabriela paid with the discount is $50.4.
How to find the amount paid with the discount?Discount is a reduction in price. Discount means reducing the price or value of an object or item.
Gabriela bought a new pair of glasses at the store when they were 30% off the sale.
The regular price of the glasses is 72 dollars. The amount Gabriela paid with the discount can be calculated as follows:
discount = 30% off of the sale
discount = 30 / 100 × 72
discount = 2160/ 100
discount = 21.6 dollars
Therefore,
price paid with the discount = 72 - 21.6
price paid with the discount = 50.4 dollar

The solutions to this system of linear equation 3x−2y=14 is ( [tex]\frac{2y + 14}{3}[/tex] , [tex]\frac{3x}{2}[/tex]-7).
Add 2y to both sides.
3x=14+2y
The equation is in standard form.
3x=2y+14
Divide both sides by 3.
[tex]\frac{3x}{3}[/tex] = [tex]\frac{2y + 14}{3}[/tex]
Dividing by 3 undoes the multiplication by 3.
x = [tex]\frac{2y + 14}{3}[/tex]

−2y=14−3x

The inequality for the number of monthly calls for which Plan 1 is more economical than Plan 2 is,

And x > 320 means that the monthly calls should be more than 320, for Plan 1 to be more economical than Plan 2.
(a) Given, that the telephone company offers two billing plans for local calls. Plan 1 charges $35 per month for unlimited calls.
Plan 2 charges $19 per month plus $0.05 per call.
Let x calls be made,
Now, according to the Plan 1,
the charges for 'x' calls be $35 only
according to the Plan 2,
the charges for 'x' calls be
$19 + $0.05x
Now, Plan 1 is more economical than Plan 2 for,
$35 < $19 + $0.05x
On solving the inequality, we get
$16 < $0.05x
On dividing both the sides by 0.05, we get
16/0.05 < x
320 < x
i.e. the monthly calls be more than 320.
(b) Now, as in part (a) we got,
320 < x
which means that the monthly calls should be more than 320, for Plan 1 to be more economical than Plan 2.
Hence, theinequality for the number of monthly calls for which Plan 1 is more economical than Plan 2 is,

The value of x is (5t-a) when the formula is 6x+a=5(x+t).
According to the question,
We have the following information:
6x+a=5(x+t)
Now, from this formula, we have to mark the value of x or in other words, we have to find the value of x.
Now, multiplying 5 into the bracket on the right hand side:
6x+a = 5x+5t
Subtracting 5x from both sides of the equation:
6x-5x+a = 5t
x+a = 5t
Subtracting a from both sides of the equation, we will get the final value of x in terms of t and a:
x = 5t-a
Hence, the value of x is (5t-a) when the formula is 6x+a=5(x+t).
