Answer:
[tex]l + w + d \leq 61[/tex]
Step-by-step explanation:
Given
Sum of l, w and d be at most 61
Required
Write as inequality
First, we need to determine the sum of l, w and d
[tex]Sum = l + w + d[/tex]
Next, we determine the type of inequality.
At most 61 means less than or equal to 61
So, the expression becomes:
[tex]Sum \leq 61[/tex]
Substitute value for Sum
[tex]l + w + d \leq 61[/tex]

The probability of event Als x, and the probability of event Bis y. If the two events are independent, which of these conditions must be true?
O A P(BA) = y
OB. P(
AB) = y
OC. P(BA) = x
OD. P(A and B) = x + y
OE
P(A and B)
P(A)
The condition that must be true about the probabilities is P(A and B) = xy
The probabilities of the events A and B are given as:
P(A) = x
P(B) = y
Given that events A and B are independent events, then we have the following equation
P(A and B) = P(A) * P(B)
The equation becomes
P(A and B) = x * y
P(A and B) = xy
Hence, the condition that must be true is P(A and B) = xy

Let p be the elevation of a passage in meters. Write an inequality that
represents elevations below -8 meters.
Answer: -8>p
Step-by-step explanation: um it just is
The required inequality is -8 > p which represents elevations below -8 meters.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that performs the arithmetic operations is called the arithmetic operator.
Let p be the elevation of a passage in meters.
We have to determine inequality that represents elevations below -8 meters.
According to the given question, translate the phrase into an algebraic form :
⇒ -8 > p or
⇒ p > 8
Therefore, the algebraic inequality represents the sentence " p less than eight"

Suppose that 10 percent of the male cadets are taller than 72 in. Assuming that the heights of the cadets are normally distributed, what is the standard deviation
Answer:
1.56
Step-by-step explanation:
Given that :
Average height (μ) = 70 in
10% are taller than 72 in ; the standard deviation Given a normal distribution :
P(x > Z) = 0.10
Using a Z probability calculator, the Z value corresponding to P(x > Z) = 0.10 is 1.282
Z = 1.282
Using the Z relation:
Z = (x - μ) / σ
σ = standard deviation x = 72
1.282 = (72 - 70) / σ
1.282σ = 2
σ = 2 / 1.282
σ = 1.5600624
σ = 1.56

car x travels 186 in 3 hours write an equation of the linethat describes the relationship between distance and time
Answer:
car x travels 62 miles an hour
Step-by-step explanation:
186 in 3 hours can also be represented by 186 divided by 3, and when this happens you would get 62 miles per hour
y=62x equation of the line that describes the relationship between distance and time.
What is Speed?Speed is the time rate at which an object is moving along a path.
Given,
car x travels 186 miles
Distance=186
Time = 3 hours
We need to find the equation of the line that describes the relationship between distance and time
This can be achieved by Speed formula.
Speed=Distance/time
Speed =y/x
Speed =186/3=62
62=y/x
Now apply cross multiplication
y=62x.
Hence, y=62x equation of the line that describes the relationship between distance and time.

chloe has three dogs. Corky weighs twice as much as muffin.Rufus weighs twice as much as corky. the total weight of the dog is 77 pounds. how much does each dog weigh?
Answer:
Corky = c = 22 pounds
Muffin = m = 11 pounds
Rufus = r = 44 pounds
Step-by-step explanation:
Let the weight of each dog be represented as
Corky = c
Muffin = m
Rufus = r
The total weight of the dog is 77 pounds.
c + m + r = 77
Corky weighs twice as much as muffin.
c = 2m
m = c/2
Rufus weighs twice as much as corky.
r = 2c
Hence
c + c/2 + 2c = 77
3.5c = 77
c = 77/3.5
c = 22 pounds
m = c/2
m = 22/2
m = 11 pounds
r = 2c
r = 2 × 22
r = 44 pounds
Each dog weighs:
Corky = c = 22 pounds
Muffin = m = 11 pounds
Rufus = r = 44 pounds

A machine paints 340 toy boats in 15 minutes. What is the Unit rate?
Answer:
about 22
Step-by-step explanation:
Answer:
340 boats
---------------
3/4 hours
Explanation:
Since we are asked to find the unit rate per hour, we must convert the minutes given into hours.
45 minutes⋅ 1 hour / 60 minutes = 3/4 hours
Now, we simply put the number of toy boats given in the problem over the total amount of time (in hours) required to paint them. Thus, our final answer is:
340 boats
------------
3/4 hours
Which equation describes the line that passes through the points (1, 3) and (– 2, 6)?
y = -x + 4
y = - 2x + 3
y = -x + 3
y = - 2x + 6
The equation y = -x + 4 describes the line that passes through the points (1, 3) and (– 2, 6).
What is a line?A line is a straight one-dimensional geometrical which has 0 wideness and extends infinitely in both directions. A line is also called a straight line.
A line is also called one-dimensional. It extends infinitely in both directions and has 0 wideness. It's not a shape since it has no form. although we used to represent points or lines as shapes because we need to actually analyze them, they don't actually have any form.
Given that two points (1, 3) and (– 2, 6) and asking which is the line passing through both points now if line passing then it should satisfy points.
By the cross, checking option is clear that in first option
3 = -1 + 4
3 = 3
and 6 = 2 + 4 =6 so its clear y = -x + 4 will be the correct line.

Drag each expression to show whether the product is less than 1, equal to 1, or greater than 1.
Answer:
See answer below
Step-by-step explanation:
Given the expressions
8 × 1/9, 4 × 4/5, 6 × 1/5, 9 × 1/2, 1 × 2/5, 9 × 1/9
We are to check which is less than 1, equal to 1 and greater than 1
For 8×1/9
8×1/9 = 8/9
8/9 = 0.889<1
Hence 8/9 is less than 1
For 4 × 4/5
4 × 4/5 = 16/5
16/5 = 3 1/5
3 1/5 =3.2>1
Hence 4 4/5 is greater than 1
For 6×1/5;
6×1/5 = 6/5
6/5 = 1.2 >1
Hence 6×1/5 is greater than 1
For 9 × 1/2:
9 × 1/2 = 9/2
9/2 = 4.5>1
Hence 9× 1/2 is greater than 1
For 1×2/5;
1×2/5 = 2/5
2/5 = 0.4<1
Hence 1×2/5 is less than 1
For 9×1/9
9×1/9 = 9/9
9/9 = 1
Hence 9×1/9 is equal to 1
