The probability that the fourth digit is 4 is 1/6.
<h3>What is the probability?</h3>
Probability is used to calculate the odds that a random event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
Probability the number is 4 = 1 / possible numbers
Possible numbers = 4, 5, 6, 7, 8, 9,
= 1/6

Answer:
2.25
Step-by-step explanation:
The number 2.25 is already in standard form.
___
In the US (and other places), "standard form" is an ordinary decimal number, with the integer part to the left of the decimal point and the fractional part to the right of the decimal point: 2.25.
In the UK (and other places), "standard form" is a number written in scientific notation with a mantissa consisting of the leading non-zero digit to the left of the decimal point, the remaining significant digits to the right of the decimal point, and a multiplier that is 10 to the power appropriate to the place value of the leading digit. When the multiplier is 1, we need not write it.
2.25 = 2.25×10⁰ (full form) = 2.25 (with superfluous 10⁰ removed)
C the input is the range and the output is the domain
Answer:
Option d is correct.
no , because y does not vary directly with x.
Step-by-step explanation:
Direct variation states that a relationship between any two variables in which one is a constant multiple of the other.
in other way, when one of the variable changes then the other changes in proportion to the first.
If y is directly proportional to x i.e,
then the equation is of the form;
where k is the constant of Variation.
From the table:
Consider any values of x and y:
Let x = 4 and y = 28
then by definition of direct variation solve for k;
28 = 4k
Divide both sides by 4 we get;
k = 7
Then the equation become: y = 7x .....[1]
Check whether the other data follows this equation or not,
x = 6 and y = 48
Substitute in equation [1];
48 = 7(6)
48 = 42 False
Also, for;
x = 8 and y= 72
72 = 7(8)
72 = 56 False
⇒ y= 7x does not follows the data of the given table.
Therefore, y does not vary directly with x.
Answer:
49 minutes
Step-by-step explanation:
9:50 to 10:00 is 10 minutes
plus the 39 minutes in 10:39
10 + 39 = 49
hope i helped
