Answer:

[tex]y-7=-6(x-1)[/tex]

Step-by-step explanation:

So first you need to find the slope of the line. You do this by doing [tex]m=\frac{y^{2}-y^{1}}{x^{1}-x^{2}}[/tex]. You would plug the points from the line into the equation to get [tex]m=\frac{1-7}{5-4}[/tex], and when you simplify you would get [tex]m=\frac{-6}{1}[/tex] or [tex]m=-6[/tex]. This means your slope is -6.

Now, point slope form is written as [tex]y-y^{1} = m(x-x^{1} )[/tex] so to write the equation you would plug in the slope and the first point to get [tex]y-7=-6(x-1)[/tex]

Answer:

the fist one = 160 - 24

the second one = 12.50 / 5

Step-by-step explanation:

Answer:

15. equation: g+24=160, and the answer is g=136

16. equation: 5d=12.50, answer is d=3.5 hours

17. 15 cakes are made when the cost is $395

Step-by-step explanation:

15: You know that there are 160 students in 7th grade. This would be on one side of the equal sign. You know that there are 24 more students in the 7th grade class than the 8th grade class. And we know that g represents the number of students in the 8th grade class. So you set up your equation as g+24=160. You would subtract 24 from both sides: g+24-24=160-24, which gives you g=136.

16: You spend $5 an hour, so, on one side, you will have 5. On the other you will have $12.50. We will let d represent dollars, and it will go with the 5 to give us 5d. The equation is 5d=12.50. From there, you will divide 5 from both sides: 5d/5=12.50/5, which gives you d=3.5.

17:  So, we have the equation, and we just plug in what we know. So, $395=24n+35. From there, we will subtract 35 from both sides. That would give us $395=24n and we will divide 24 from both sides to give us n=15 cakes.

Answer:

3/2

Step-by-step explanation:

There are a lot of fractions that equal 1.5, but if you're asking for the most simplified fraction, 3/2 is the answer.

The required equation of the line in slope intercept form is given as 2x + y = 3

Given that,
To determine the linear equation in slope-intercept form passing through the point with the given slope. (0, 3); slope = -2.

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Equation of the line is given as,

y - y₁ = m (x - x₁)
Substitute the value in the equation,

y - 3 = -2 (x - 0)
y = -2x + 3
2x + y = 3

Thus, the required equation of the line in slope intercept form is given as 2x + y = 3

The answer is answering "What is 480% as a fraction in simplest form?"

The probability that the average petal length will be between 1.3 and 1.6cm will be 0.5328.

From the complete question, x has an approximately normal distribution with a mean of 1.5cm and standard deviation of 0.2cm.

The associated probability for z values will be found in the normal distribution table and the probability will be subtracted. This will be:

= 0.6915 - 0.1587

= 0.5328

In conclusion, the probability that the average petal length will be between 1.3 and 1.6cm is 0.5328.

The two parallel lines will be b and d in the given question

From the figure, we can see that

Angles formed by lines b and a are 89. 5 degrees

Angles formed by lines c and a are 91.5 degrees

Angles formed by lines d and a are 89.5 degrees

Angles formed by lines e and a are  88.5 degrees

Angles formed by lines f and a are   90.5 degrees

Since the angle formed by line b with a and d with a are equal that is 89.5

so these two lines will never intersect each other

But other lines have varied angles then they can intersect at one point

Thus the two parallel lines will be b and d in the given question

Answer and explanation:

There should be 85.6% correctly made products

If there is less than 85.6% correctly made products then production would be shut down

therefore 100-85.6= 14.4% of products can be incorrectly made and not more than that

In 30 batches 14.4% =0.144*30=4.32 products

Therefore there must not be more than 4.32 products incorrectly made in a batch of 30 else production is shut down

The series: 2 + 4 + 6 +.... is an arithmetic series

The sum of T41 to T47 is 616

The series is given as:

2 + 4 + 6 +....

The above series is an arithmetic series with the following parameters:

Initial value, a = 2

Common difference, d = 2

Start by calculating S40 using the sum of n terms formula

[tex]S_n = \frac n2 * [2a + (n - 1)d][/tex]

So, we have:

[tex]S_{40} = \frac {40}2 * [2*2 + (40 - 1)*2][/tex]

[tex]S_{40} = 1640[/tex]

Calculate S47 using the same formula

[tex]S_{47} = \frac {47}2 * [2*2 + (47 - 1)*2][/tex]

[tex]S_{47} = 2256[/tex]

Subtract S40 from S47

[tex]S_{47} - S_{40} = 2256 - 1640[/tex]

[tex]S_{47} - S_{40} = 616[/tex]

Hence, the sum of T41 to T47 is 616
