Answers
Answer:
1)[tex]4.51[/tex]×[tex]10^-3[/tex]
2) .00632
Step-by-step explanation:
1.Which of the following is equivalent to 0.00451?
= [tex]\frac{451}{100000}[/tex]
=[tex]\frac{4.51}{1000}[/tex]
=[tex]\frac{4.51}{10^3}[/tex]
= [tex]4.51[/tex]×[tex]10^-3[/tex]
Therefore the answer is (a)
===================================================================
Which of the following is equivalent to 6.32 x 10-*3?
In order to find the answer to this question you can just put the notation into standard form which means they will be equivalent to each other.
The exponent is negative so you move to the left:
[tex]6.32=.00632[/tex]
=[tex].00632[/tex]
Therefore 6.32*10^-3 is equivalent too (c) .00632
1. A new drill is used to dig a hole in the ground. At noon, the hole is 13.2 feet deep when the new drill is turned on for the first time that day. At 2 p.m., the drill has dug the hole to be feet deep. The new drill dug 1.5 times as much of the hole as the old drill would have in the same length of time.
(a) What expression represents the number of feet the new drill dug?
(b) How many feet would the old drill have dug in the same length of time? Show your work. Answer the question in a complete sentence.
Answers
Using the subtraction and division operation, the depth dug by the new drill, and the depth that would have been dug by the old drill are 29.05 feets and 19.37 feets respectively.
The expression for the number of feets dug by the new drill can be calculated thus :
Final depth - Initial depthDepth dug = 42.25 feets - 13.2 feets
Depth dug = 29.05 feets
The new drill dug 1.5 times the depth that woukd have been dug by the old drill :
Depth dug by old drill = 29.05 / 1.5
Depth dug by old drill = 19.37 feets
Therefore, the depth dug by old drill will be 19.37 feets

Step-by-step explanation:
A die is rolled twice. What is the probability of showing a 4 on both rolls?
Answers
Answer:
1/36
Step-by-step explanation:
So what you have to do is take all the numbers on the dice. Getting a 4 would be a 1 in 6 (1/6) chance, but then you take the risk of rolling again and trying to get another 4. Nothing changes with the amount of sides, so it would just be another 1/6 change to get the 4. Then, you have to multiply the two changes together. SO 1/6 x 1/6 = 1/36. It is a 1/36 chance to role a 4 on both roles.
The probability of an event is a number between [tex]0[/tex] and [tex]1[/tex]. Hence, the probability of showing a [tex]4[/tex] on both the rolls is [tex]\frac{1}{36}[/tex].
What is probability?
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between [tex]0[/tex] and [tex]1[/tex].
The probability of the first throw [tex]4[/tex] is [tex]\frac{1}{6}[/tex].
And on the second throw is [tex]\frac{1}{6}[/tex].
For both, the throws probability [tex]4[/tex] would be
[tex]\frac{1}{6}[/tex]×[tex]\frac{1}{6}[/tex][tex]=\frac{1}{36}[/tex]
Hence, the probability of showing a [tex]4[/tex] on both the rolls is [tex]\frac{1}{36}[/tex].

Answers
Answer:
51
Step-by-step explanation:
1. The median of a data set is the quantity that's in the middle of the data points. Before looking what number is in the middle, you have to order them from least to greatest.
15, 33, 51, 51, 752. Now, when crossing from left to right then left to right again, you end up with 51 in the middle.
Therefore, the median number is 51.
th LEARNING TASK & Equation FIND THE THE EQUATION OF THE LINE, WRITE STANDARD FORM. THE SLOPE is 5 passing through (-1,4).
Answers
Step-by-step explanation:
to find the equation of a line having the slope use this formula:
[tex]y - yp = m(x - xp)[/tex]
in which:
- yp is the y of the point (so 4);
- m is the slope (so 5);
- xp is the x of the point (so -1)
so:
[tex]y - 4 = 5(x - ( - 1))[/tex]
[tex]y - 4 = 5x + 5[/tex]
[tex]y=5x + 5 + 4[/tex]
[tex]y = 5x + 9[/tex]
