Answer:
x = 11.5, y = -5.5.
As an ordered pair this is (11.5, -5.5).
Step-by-step explanation:
2x+4y=1 Multiply this by 3:
3x+5y=7 Multiply this by -2.
6x + 12y = 3
-6x - 10y = -14 Adding these 2 equations:
0 + 2y = -11.
y = -11/2
y = -5.5.
Now plug this into the first equation:
2x + 4(-5.5) = 1
2x = 1 + 22
x = 23/2
x = 11.5.

There are 9 counters in a bag.
7 of the counters are green.
2 of the counters are blue.
Ria takes at random two counters from the bag.
Work out the probability that Ria takes one counter of each colour.
You must show your working.
Please show the full working out so I know how to get full marks in future I’ll give brainiest
Answer:
7/18
Step-by-step explanation:
Probability is the ratio of the number of possible outcomes to the number of total outcomes.
Given that there are 9 counters in a bag, 7 are green while 2 are blue.
the probability of picking at random a
Green counter = 7/9
Blue counter = 2/9
The probability that Ria takes one counter of each colour if 2 counter are picked as random is Green and Blue or Blue and Green
This is
=7/9 * 2/8 + 2/9 * 7/8
Recall that when a counter is picked the number of that ball available reduces and so does the total number of counter
=14/72 + 14/72
= 28/72
= 7/18

Lola already has 6 pennies, and she plans to save more. In her first week
of saving pennies, she will save twice the number of pennies that she
already has. Each week after, she will save twice the number of pennies
as the previous week.
Which equation can be used to determine the number of pennies, P, Lola
will save during week w of saving pennies?
Answer: [tex]P=6(2)^{w-1}[/tex]
Step-by-step explanation:
Here, the money saved each week follows geometric progression with a common ratio r= 2 and first term a= 6.
In geometric progression, nth term = [tex]ar^{n-1}[/tex]
Substitute r= 2 , a= 6 and n=w, we get
wth term = [tex]6(2)^{w-1}[/tex]
The equation can be used to determine the number of pennies, P, Lola will save during week w of saving pennies:
[tex]P=6(2)^{w-1}[/tex]
The areas of the squares adjacent to two sides of a right triangle are shown below.
? units?
35 units
50 units
What is the area of the square adjacent to the third side of the triangle?
Answer:
85
Step-by-step explanation:
All you do is add 35 units and 50 units together.
Area of the square adjacent to the third side of the triangle is 85 units square
What is Pythagoras theorem?Pythagoras theorem states that a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.
Given that areas of the squares adjacent to two sides of a right triangle are :
35 sq units
50 sq units
To determine the area of the square adjacent to the third side of the triangle
According to Pythagoras theorem,
Hypotenuse² = Base² + Perpendicular²
As figure is missing assuming given sides are perpendicular sides
Then Area of the square adjacent to the third side of the triangle = 35 + 50
= 85 units square
Now, assuming 50 sq unit is an area on hypotenuse
Then Area of the square adjacent to the third side of the triangle = 35 - 50
= 15 units square

Answer:
it is a 60 30 90 triangle so basically 2y is = x
21² + y² = x²
441 + y² = x²
y = x/2 (2y = x)
441 + x²/4 = x²
4x² = 1764 + x²
3x² = 1764
x = exact is 24.248711306 simplied square root would just be 14√3

Chase plans to buy a new car and determines he can budget $725 monthly for four years. His bank is offering an 8 25% annual interest rate What is the maximum loan he can afford to stay in his budget? Use the formula, A = (p[(1 + r/n) ^ m - 1])/(1/n * (1 + r/n) ^ N) , where Pis the monthly payment, the annual interest rate, nis the number of times interest is compounded in one year and is the number of years.
Answer:
$29555.20
Step-by-step explanation:
Given that:
P = $725
r = 8.25% = 0.0825
n = 12
t = 4 years
From the given formula:
[tex]A = \dfrac{P{(1+\dfrac{r}{n})^{n*t}-1 } }{\dfrac{r}{n}(1+ \dfrac{r}{n})^{nt}}}[/tex]
[tex]A = \dfrac{725{(1+\dfrac{0.0825}{12})^{12*4}-1 } }{\dfrac{0.0825}{12}(1+ \dfrac{0.0825}{12})^{4\times 12}}}[/tex]
[tex]A = \dfrac{725{(1.3894-1 )} } { 0.006875 \times 1.3894 }[/tex]
A = $29555.20
A certain statistic bˆ is being used to estimate a population parameter B . The expected value of bˆ is equal to B . What property does bˆ exhibit? The sampling distribution of bˆ is normal. The sampling distribution of b hat is normal. A The sampling distribution of bˆ is binomial. The sampling distribution of b hat is binomial. B The sampling distribution of bˆ is uniform. The sampling distribution of b hat is uniform. C bˆ is unbiased. B hat is unbiased. D bˆ is biased.
Answer:
C bˆ is unbiased.
Step-by-step explanation:
In statistics, the sampling distribution showcases the distribution of obtained values by the statistics in all possible sample sizes of the same population. A statistic that estimates a population parameter is termed to be an unbiased estimator if the mean of such distribution appears to be equal to the true value of the estimated parameter.
Thus, from the aforementioned, the property exhibited by b- is unbiased.
d is biased
Step-by-step explanation:
The expected value of d is not D
The property where the expected value of d is D is called unbaisedness, hence d is biased

Suppose each block is 300 ft long. Suppose I could fly and walk through people’s houses and yards so that I could travel a straight line from my house to the library. What distance would I travel?
Answer:
1615.55 ft
Step-by-step explanation:
The coordinates for house (300,300)
Library coordinate =(1800, 900)
Distance between two points :
D = sqrt[(x2 - x1)² + (y2 - y1)²
D = sqrt[(1800 - 300)² + (900 - 300)²
D = sqrt[(2250000 + 360000)]
D = sqrt[(2610000)]
D = 1615.5494
D = 1615.55 ft

The organizers of a concert are preparing for the arrival of 50,000 people in a field. Each person is alloted 5 square ft of space, so the
organizers rope off a circular area big enough to account for 5 square feet per person. Find the radius of this region, rounding to the nearest
foot.
Answer:
Radius of park r = 282.04 ft (Approx)
Step-by-step explanation:
Given:
Number of people = 50,000
Each person needs area = 5 ft²
Park's is in shape of circle
Find:
Radius of park r
Computation:
Total area required = 50,000 x 5
Total area required = 250,000 ft²
Area of circular park = Total area required
πr² = 250,000
(22/7)r² = 250,000
r² = 79545.4545
r = 282.04 ft
Radius of park r = 282.04 ft (Approx)
