Answer:

the first option (89.91) is the greatest

By rounding to 1 significant figure 542.04 × 1.88 equal to 1019.0352

is 1019.

We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.

To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.

Given we have to round off 542.04×1.88 = 1019.0352.

Now rounding off to one significant digit means we should have only one digit after the decimal place and the second digit after the decimal place is 3 which is less than 5.

∴ 1019.0352 rounded off to one significant digit is 1019.

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

A line with a slope of 1/3 using the y=mx+b line slope equation would be:

y=1/3x+b

We can now plug the x and y values into this equation with x being -6 and y being 2.

2=1/3 * -6 +b

2= -2 +b

b=4

Therefore the equation is

y=1/3x+4

Answer:

Mean of the binomial distribution

μ = 174.972 bolts

Step-by-step explanation:

Step(i):-

Given that Bob tested 24 bolts that he randomly picked and found that 5 were defective

The proportion of the defective item

            [tex]p = \frac{x}{n} = \frac{5}{24} = 0.2083[/tex]

Step(ii):-

Let 'x' be a random variable in a binomial distribution

Answer:

3(6-x)

Step-by-step explanation:

The expression "Triple the difference of six less than a number" can be represented as 3 * (x - 6), where x represents the number.

To mathematically represent "Triple the difference of six less than a number," we can use the following expression:

3 * (x - 6)

Here, x represents the number, and the expression calculates the difference between the number and six, which is then multiplied by three.

Answer:

[tex]R' = (-1,-0.5)[/tex]

Step-by-step explanation:

See attachment for complete question.

From the attachment:

[tex]P = (-3,-3)[/tex]

[tex]R = (1,2)[/tex]

Dilation:

[tex]D_{(0.5,P)}[/tex]

Required

Determine R'

First, subtract the coordinates of P from R. This means that R is measured from P.

[tex]R = (1-(-3),2-(-3))[/tex]

[tex]R = (1+3,2+3)[/tex]

[tex]R = (4,5)[/tex]

Next, apply dilation factor 0.5

[tex]R' = R * 0.5[/tex]

[tex]R' = (4,5) * 0.5[/tex]

[tex]R' = (4* 0.5,5* 0.5)[/tex]

[tex]R' = (2,2.5)[/tex]

Lastly, measure R' from the origin by adding the coordinates of P to R'

[tex]R' = (2+(-3),2.5+(-3))[/tex]

[tex]R' = (2-3,2.5-3)[/tex]

[tex]R' = (-1,-0.5)[/tex]

Dilation of a figure or image is to enlarge or shorter it from the original length by a scale factor.

The coordinate of the R' after the dilation is (-1,-0.5)

Dilation of a figure or image is to enlarge or shorter it from the original length by a scale factor.

Given information-

The points of PQRS are Q(-3,2), R(1,2), P(-3,-3), S(1,-3).

The given points are dilated. This dilation can be measured by subtracting the point P from each point . Thus the point of Q is,

[tex]Q'=Q-P\\Q'=(-3-(-3), 2-(-3))\\Q'=(0,5)[/tex]

Similarly,

[tex]R'=R-P= (1-(-3),2-(-3))=(4,5)\\P'=P-P=(-3-(-3), 3-(-3)=(0,0)\\S'=S-P=(1-(-3),-3-(-3))=(4,0)\\[/tex]

As the dilation factor is 0.5. Thus, the point of Q is,

[tex]Q"=(0.5)\times(0,5)=(0,2.5)[/tex]

Similarly,

[tex]R"=(0.5)\times(4,5)=(2,2.5)\\P"=(0.5)\times(0,0)=(0,0)\\S"=(0.5)\times(4,0)=(2,0)\\[/tex]

Add the points P back, to the above coordinate plane to get the dilation point. Thus the point of Q is,

[tex]Q'''=(0,+(-3), 2.5+(-3))\\Q'''=(-3,-0.5)[/tex]

Similarly,

[tex]R'''=(2+(-3),2.5+(-3))=(-1,-0.5)\\P'''=(0+(-3),0+(-3))=(-3,-3)\\S'''=(2+(-3),0+(-3))=(-1,-3)\\[/tex]

Thus the coordinate of the R' after the dilation is (-1,-0.5)

Answer:

(-3,-4)

If it was on the y-axis it would be (3,4)

Step-by-step explanation:

Rx-axis (P) = (-3, -4)

"When we reflect a point about x-axis then the x-coordinate remains the same, but the y-coordinate changes its symbol."

For given example,

we have been given a point P = (-3, 4)

We need to find  Rx-axis (P)

That is we need to reflect given point about x-axis.

We know, when we reflect a point about x-axis then the x-coordinate remains the same, but the y-coordinate changes its symbol.

So, the reflected point would be (-3, -4)

Therefore, Rx-axis (P) = (-3, -4)
