Answer:

The equation is;

y = -1/4x + 607.5

Step-by-step explanation:

Let us have the number of drops as y axis while the number of minutes is x axis

The points to use are;

(30,600) and (130,575)

The slope can be calculated using;

m = (y2-y1)/(x2-x1)

= (575-600)/(130-30) = -25/100 = -1/4

So the equation as we model using the normal equation of a straight line (y = mx + c, m is slope and c is the intercept)

y = -1/4x + c

To get c, we simply substitute one point

Let us use (30,600)

We have

600 = -1/4(30) + c

600 + 7.5 = c

c = 607.5

So the equation is ;

y = -1/4x + 607.5

Answer:

x=2, y=1

Step-by-step explanation:

since they are both congruent, the corresponding sides are also congruent

Thus:

2x+1=x+3

x+y=3x-3y

First, solve 2x+1=x+3

[tex]2x+1=x+3[/tex]

Subtract both sides by x

[tex]2x-x+1=x-x+3\\[/tex]

[tex]x+1=x+3[/tex]

Subtract both sides by 1

[tex]x+1-1=x+3-1[/tex]

[tex]x=2[/tex]

Thus x=2

Next, solve for x+y=3x-3y

[tex]x+y=3x-3y[/tex]

Substitute x with 2 (from the first part)

[tex]2+y=3(2)-3y[/tex]

[tex]2+y-y=6-3y-y[/tex]

[tex]2=6-4y[/tex]

[tex]2-6=6-4y-6[/tex]

[tex]\frac{-4=-4y}{-4}[/tex]

[tex]y=1[/tex]

Thus y=1

Answer:

2.958

Step-by-step explanation:

Sample mean (x) = 38.2 MPG

Population mean (μ) = 37.9 MPG

Sample size (n) = 140

Standard deviation (σ) = 1.2

The test statistic (Tstat) can be obtained thus :

(x - μ) / σ/sqrt(n)

Tstat = (38.2 - 37.9) / 1.2/sqrt(140)

Tstat = 0.3 / 0.1014185

Tstat = 2.9580401

Test statistic = 2.958

Answer:

Ram bought that motorcycle for Rs. 36000

Step-by-step explanation:

Given that:

Amount gained = 25%

Selling price of motorcycle = Rs. 45000

As 100% will be the original price, then 25% will be added into it.

125% will be the new percentage.

Let,

x be the original price of motorcycle.

125% of x = 45000

[tex]\frac{125}{100}x=45000[/tex]

1.25x=45000

Dividing both sides by 1.25

[tex]\frac{1.25x}{1.25}=\frac{45000}{1.25}\\[/tex]

x=36000

Hence,

Ram bought that motorcycle for Rs. 36000

Answer:

7/12

Step-by-step explanation:

Step 1: So we multiply 11 by 3, and get 33.

Then we multiply 1 by 12, and get 12.

Next we give both terms new denominators -- 12 × 3 = 36.

So now our fractions look like this:

33/36 -  12/36

Step 2: Since our denominators match, we can subtract the numerators.

33 − 12 = 2

So the answer is:

21/36

Step 3: Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

To find out, we try dividing it by 2...

Nope! So now we try the next greatest prime number, 3...

Are both the numerator and the denominator evenly divisible by 3? Yes! So we reduce it:

21/36 ÷ 3 =7/12

so your answer should be 7/12

The fractional expression 11/12 – 1/3 is simplified, as 7 / 12.

A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of numerator and denominator.

The expression is given below.

⇒ 11/12 – 1/3

On simplifying the expression, we have

⇒ 11/12 – 1/3

⇒ 11/12 – 4/12

⇒ (11 – 4) / 12

⇒ 7 / 12

Answer:

The supplier is less accurate than they have claimed

Step-by-step explanation:

Given that:

95% confidence interval of supplier's claim :

(20.45, 21.05)

Mean = (20.45 + 21.05) /2 = 41.5 / 2 = 20.75

Error margin = (upper bound - mean) = 21.05 - 20.75 = 0.30

95% confidence interval of your sample :

(20.48, 21.02)

Mean : (20.48 + 21.02) /2 = 41.05 / 2 = 20.75

Error margin = (upper bound - mean) = 21.02 - 20.75 = 0.27

0.3 > 0.27

From the calculations made, the mean are the same, but the error margin of supplier is higher, thus it could be concluded that the supplier is less accurate than they have claimed

Answer:

Step-by-step explanation:

(4a - 3)/(3b + 1) = 39/(a + 1) You are not going to get a numerical answer for this. Cross multiply

(4a - 3)(a + 1) = 39(3b + 1)

4a^2 + a - 3 = 117b + 39

4a^2 + a - 42 = 117b

b = [tex]\frac{a^2 +a - 42}{117}[/tex]

Answer:

b = 3

Step-by-step explanation:

I think that the relations are the following

[tex]\frac{QP}{XY}=\frac{RS}{VZ}=\frac{PT}{XW}\\\\\frac{39}{13}=\frac{4a-3}{a+1}=\frac{5a+6b}{5b+1}\\\\3=\frac{4a+3}{a-1}=\frac{5a+6b}{5b+1}[/tex]

so we first solve for a and then for b

[tex]3=\frac{4a-3}{a+1}\\\\3(a+1)=4a-3\\\\3a+3=4a-3\\\\4a-3a=3+3\\\\a=6[/tex]

and now for b

2.5 inches steel wire

We can use an equation to find the answer. 750/300 = 2.5

Answer:

2.5 inches of steel wire are needed to make one spring.

Step-by-step explanation:

In order to answer this, we can set up a proportion (setting two fractions equal to each other) to solve for how many inches of steel wire are needed to make one spring.

We are given a ratio: 750 inches of steel wire are required to make 300 springs. Therefore, this is represented as:

[tex]\bullet \ \ \ \text{750 inches of steel wire : 300 springs}[/tex]

This can be rewritten in fraction form:

[tex]\displaystyle \bullet \ \ \ \frac{\text{750 inches of steel wire}}{\text{300 springs}}[/tex]

Therefore, we have our first proportion.

We want to make one spring, so we need to find how much steel is required to make one spring. Therefore, for our second fraction, the inches of steel wire is unknown. We can define this as x.

[tex]\bullet \ \ \ \text{x inches of steel wire}[/tex]

Finally, our ratio can be written in the same manner as the previous ratio:

[tex]\bullet \ \ \ \text{x inches of steel wire : 1 spring}[/tex]

This can be rewritten in fraction form:

[tex]\displaystyle \bullet \ \ \ \frac{\text{x inches of steel wire}}{\text{1 spring}}[/tex]

Now, we need to set up our proportion. We do this by setting our two ratios equal to each other.

[tex]\displaystyle \bullet \ \ \ \frac{\text{750 inches of steel wire}}{\text{300 springs}} = \frac{\text{x inches of steel wire}}{\text{1 spring}}[/tex]

To solve a proportion, we need to cross multiply. We can flip our fractions and solve for the reciprocal since there is not really a way to represent cross-multiplication.

[tex]\displaystyle \bullet \ \ \ \frac{\text{750 inches of steel wire}}{\text{300 springs}} = \frac{\text{1 spring}}{\text{x inches of steel}}[/tex]

First, we can drop our labels/units.

[tex]\displaystyle \bullet \ \ \ \frac{750}{300} = \frac{1}{\text{x}}[/tex]

Then, we can multiply across.

[tex]\displaystyle \bullet \ \ \ 750 = 300x[/tex]

Finally, we can solve for x.

[tex]\displaystyle 750 = 300x\\\\\frac{750}{300}=\frac{300x}{300}\\\\2.5 = x\\\\x = 2.5[/tex]

Therefore, to make one spring, exactly 2.5 inches of steel wire are needed.
