Answers
Answer:
x = 1.155
x = -1.155
Step-by-step explanation:

ii) collect like terms3x² = 4
iii) divide both sides of the equation by 3[tex] \frac{ {3x}^{2} }{3} = \frac{4}{3} [/tex]

Answer:
i) The probability of getting 50 cent coin is 5/18, or approximately 28%
ii) To scale the numbers up to let us have 65 fifty cent coins, there would be a total of 234 coins
Step-by-step explanation:
We are told the probability of choosing ten and 20 cent coins, and from that we can work out the probability for the 50 cent coin. All we need to do is add up the other two probabilities and subtract them from 1.
[tex]p = 1 - (\frac{1}{3} + \frac{7}{18})\\p = 1 - (\frac{6}{18} + \frac{7}{18})\\p = 1 - \frac{13}{18}\\p = \frac{5}{18}\\[/tex]
So the chance of getting a 50 cent coin is five eighteenths, or approximately 28%
For the second question We are asked to find the total number of coins if there are 65 fifty cent coins. (I can't see the text below that, but presumably it's saying that the ratios will stay the same).
We can solve this by comparing the two ratios, with x as the total, and solving for x:
[tex]\frac{5}{18} = \frac{65}{x}\\5x = 65 * 18\\x = 13 * 18\\x = 234[/tex]
So to keep the same ratios and have 65 fifty cent coins, we would need a total of 234 coins.

What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
At the school carnival, the soccer team sold hamburgers and hot dogs. A person buying one hamburger and one hot dog will spend $17.65. The soccer team sold 22 hamburgers and 39 hot dogs and made $511.55.
Let x be the cost of hamburgers and y be the cost of hot dogs. Then the equation will be
x + y = 17.65 ...1
22x + 39y = 511.55 ...2
Solve the equations, then we have
22(17.65 - y) + 39y = 511.55
388.3 - 22y + 39y = 511.55
17y = 123.25
y = $7.25
Then the value of x will be
x + 7.25 = 17.65
x = 17.65 - 7.25
x = $10.40
The cost of the hamburger and hot dog will be $10.4 and $7.25, respectively. Then the correct option is D.

What value of x is in the solution set of 2(3x – 1) > 4x – 6?
It could only be the following :
A. -10
B. -5
C. -1
D. -3
Answers
Answer:
-1
Step-by-step explanation:
Given the equation :
2(3x – 1) > 4x – 6
Open the bracket :
6x - 2 > 4x - 6
Collect like terms
6x - 4x > - 6 + 2
2x > - 4
Divide both sides by 2
2x /2 > - 4/2
x > - 2
Since x > - 2
-10, - 5, - 3 are all < - 2
Hence, the only option greater than - 2 is - 1

What is Distributive Property?The distributive property is also known as the distributive law of multiplication over addition and subtraction. The name itself signifies that the operation includes dividing or distributing something. The distributive law is applicable to addition and subtraction. Let us learn more about the distributive property in this page.
The distributive property states that an expression which is given in form of A (B + C) can be solved as A × (B + C) = AB + AC. This distributive law is also applicable to subtraction and is expressed as, A (B - C) = AB - AC. This means operand A is distributed between the other two operands.
Given:
48 + 72
Now, factorize the above into prime factors
48 = 2 x 2 x 2 x 2 x 3
and, 72 = 2 x 2 x 2 x 3 x 3
Now, rewriting
48 + 72
= 2 x 2 x 2 x 2 x 3 + 2 x 2 x 2 x 3 x 3
= 2 x 2 x 2 x 3 (2 + 3)
=24 (2+3)
Hence, the expression can be written as 24 (2+3).

Answer:
-4
Step-by-step explanation:
If you look at the table closely for the value of x decreases by 2 like the first value is 7 then it goes to 5 then it goes to 3 then to 1, and if you look at the values of y it decreases by 20 like the first number is 66 then 46 then 26 then 6.
But in the table it asks the missing value of y when x is 0 not -1 so for difference of 1 instead of the usual 2 in the pattern the value of y would decrease by 10 instead of 20 so 6-10 would be -4
so the missing value of y is -4

A supplier of digital memory cards claims that less than 1% of the cards are defective. In a random sample of600 memory cards, it is found that 3% are defective, but the supplier claims that this is only a sample fluctuation. At the 0.01 level of significance, test the supplier's claim that less than 1% are defective. Use the p-value method.
Answers
Answer:
The decision rule is
Fail to reject the null hypothesis
The conclusion is
The is no sufficient evidence to support the claim that the less than 1% of the cards are defective
Step-by-step explanation:
From the question we are told that
The sample size is [tex]n = 600[/tex]
The population proportion of defective samples is p = 0.01
The sample proportion of defective samples is [tex]\^ p = 0.03[/tex]
The level of significance is [tex]\alpha = 0.01[/tex]
The null hypothesis is [tex]H_o : p = 0.01[/tex]
The alternative hypothesis is [tex]H_a: p < 0.01[/tex]
Generally the test statistics is mathematically represented as
[tex]t = \frac{\^ p - p }{ \sqrt{ \frac{p( 1 - p )}{n} } }[/tex]
=> [tex]t = \frac{0.03 - 0.01 }{ \sqrt{ \frac{0.01( 1 - 0.01 )}{600} } }[/tex]
=> [tex]t = 0.00406[/tex]
From the z table the area under the normal curve to the left corresponding to 0.00406 is
[tex]p-value = P(Z < 0.00406 ) = 0.50162[/tex]
comparing the p-valve and the level of significance we see that the
[tex]p-value > \alpha[/tex] hence
The decision rule is
Fail to reject the null hypothesis
The conclusion is
The is no sufficient evidence to support the claim that the less than 1% of the cards are defective

Cats as pet in 1995 = 57 million
Cats as pet in 2003 = 61 million
Find:
Cats as pet in 2015
Computation:
Difference in year = 2003 - 1995
Difference in year = 8 year
Difference in year = 2015 - 2003
Difference in year = 2015 - 2003
Difference in year = 12 year
Difference in number = 61 - 57
Difference in number = 4 million
