There are 36 squares on each red and white checkered tablecloth. How many squares are there on 7,011 tablecloths? huryyyyyyyyyyyyyyyyyyy plz :(
Multiplying means adding a value a given number of times to zero
The number of squares in 7,011 tablecloths is 252,396 squares
The above number of squares in 7,011 tablecloths is correct for the following reason:
The known number of squares on each red and white checkered tablecloth = 36 squares
Required:
The number of squares in 7,011 tablecloths
Solution;
To find the number of squares on the 7,011 tablecloths, we have;
Number of squares in a given number of units of tablecloth = Number of squares per unit of tablecloth × Number of tablecloths
∴ Number of squares in 7,011 tablecloths = 36 squares × 7,011 tablecloth
Number of squares in 7,011 tablecloths = 36 squares × 7,011 tablecloth = 252,396 squares
The number of squares in 7,011 tablecloths = 252,396 squares

The amount of gasoline sold each month to customers at Bob's Exxon station in downtown Navasota is a random variable. This random variable can be described as having a normal distribution with mean 2500 gallons and a standard deviation of 200 gallons (and there is no seasonal variation in sales). Exxon will give Bob an all-expense paid trip to College Station, including a free dinner at Burger King, if his station pumps more than 2800 gallons in any one month.
What is the probability that Bob will win that wonderful trip on the basis of his gasoline sales this month?
Answer:
The probability that Bob will win that wonderful trip on the basis of his gasoline sales this month
P(X≥ 2800) = P(Z₁≥1.5) = 0.0768
Step-by-step explanation:
Step(i):-
Mean of the Population (μ) = 2500 gallons
Standard deviation of the population (σ) =200 gallons
Let 'X' be a random variable in Normal distribution
Given X = 2800
[tex]Z = \frac{x-mean}{S.D} = \frac{2800-2500}{200} = 1.5[/tex]
Step(ii):-
The probability that Bob will win that wonderful trip on the basis of his gasoline sales this month
P(X≥ 2800) = P(Z₁≥1.5)
= 0.5 - A(Z₁)
= 0.5 - A(1.5)
= 0.5 -0.4232 ( from normal table)
= 0.0768
Conclusion:-
The probability that Bob will win that wonderful trip on the basis of his gasoline sales this month
P(X≥ 2800) = P(Z₁≥1.5) = 0.0768

Answer:
Second, first, fourth, third.
Step-by-step explanation:
Second, first, fourth, third
Answer:
from least to greatest:
sea grass, red algae, green seaweed, mangrove.
mangrove is the shallowest depth
sea grass is the deepest
if the question is asking which is the deepest, then the answer is sea grass.
if the question is asking which number has the greatest value, the answer is mangrove.
if the question is asking which number has the greatest absolute value, then the answer is sea grass.
my guess is to start with mangrove. so put the values in as mangrove, green seaweed, red algae, sea grass.
if this is not correct, which it should be, put in these values as the opposite order. This is based on how you interpret the question.

A pile of string measures to be 4 5/6 feet long. For a project Ms. Thompson wants to cut the long piece of string into several smaller pieces. Each piece that she cuts will measure 2/3 feet. How many whole pieces can she cut from the original piece of string if each piece is 2/3 feet long?
Answer:
7 pieces
Step-by-step explanation:
change 4 5/6 into an irregular fraction. 29/6
divide 29/6 by 2/3. to do this, flip and multiply
29/6 * 3/2 = 87/12 = 7.25 or 7 whole pieces

The diameter of bushings turned out by a manufacturing process is a normally distributed random variable with a mean of 4.035 mm and a standard deviation of 0.005 mm. A sample of 25 bushings is taken once an hour. (a) Within what interval should 95 percent of the bushing diameters fall
Complete question is;
The diameter of bushings turned out by a manufacturing process is a normally distributed random variable with a mean of 4.035 mm and a standard deviation of 0.005 mm. A sample of 25 bushings is taken once an hour.
a. Within what range should 95 percent of the bushing diameters fall?
b. Within what range should 95 percent of the sample means fall?
c. What conclusion would you reach if you saw a sample mean of 4.020?
Answer:
A) (4.0252, 4.0448).
B) (4.0331, 4.0369).
C) If i saw a sample mean of 4.020, i would conclude that the sample came from a population that did not have a population mean equal to 4.035
Step-by-step explanation:
A) We know that an approximate 95% confidence interval for the item in question has a range of diameter given by the equation;
Range = x¯ ± 1.96σ
Now, since we have a mean of 4.035 mm and a standard deviation of 0.005 mm, we can solve;
Range of bushing diameter = 4.035 ± (1.96 × 0.005) = 4.035 ± (0.0098)
= 4.0252 or 4.0448 and it can be written as;(4.0252, 4.0448).
B) We also know that In the large-sample case, a 95% confidence interval estimate for the population mean is given by the formula;
CI = x¯ ± (1.96s/√n))
Thus, if we solve, we get;
CI = 4.035 ± (1.96 × 0.005 )/√25
CI = 4.035 ± 0.0019
or (4.0331, 4.0369).
c. If i saw a sample mean of 4.020, i would conclude that the sample came from a population that did not have a population mean equal to 4.035 because it doesn't fall into the range of confidence intervals we got earlier.

Explain the process to solve the equation. Use proper vocabulary in your explanation. One-fourth x = negative five-eighths
Answer:
-2.5
Step-by-step explanation:
Your want to isolate the x. This is a multiplication problem, so use the inverse operation, which is division. Divide both sides of the equation by
1/4 by multiplying by the reciprocal, 4. (− 5
8)(4) is − 5/2. Use substitution to check the answer. x = − 5/2 :)
Answer: First, you isolate x by dividing 1/4 on both sides.
1/4x divided by 1/4 equals zero, which just leaves x, and -5/8 divided by 1/4 equals -5/2, so x = -5/2. -5/2 can be simplified to -2.5,
To check the answer, substitute x for -5/2:
* 1/4 multiplied by -5/2 equals -5/8
* 5/8 = 5/8, so this proves that my answer is correct.
Erik is building a cubby bookshelf, that is, a book shelf divided into storage holes (cubbies) instead of shelves. He wants the height of the bookshelf to be x2−4x−45
and the width to be x2+7x+10. Each cubby hole in the bookshelf will have a height of x+2 and width of x−9
.
Answer:
Step-by-step explanation:
Factor your equations using the fact that x²-Sx+P represents the general equation where S is the sum of roots and P the product of roots.
What roots will have the sum S=4 and product P= -45 ,
will have 5 and -9, S=5-9=-4✅ and P=5*(-9)=-45✅
x²-4x-45 = (x-root1) (x-root2) = (x+5)(x-9)
S=-7 and P=10 , so the roots are -5 and -2
x²+7x+10= (x+5)(x+2)
I am not sure what is your question yet you frobably need to factor the 2 given equation so you will have a bookshelf of (x+5)(x-9) by (x+5)(x+2)

Angles and Lines
We must recall some properties of angles and lines:
Linear pair of angles: Two angles are linear if they are adjacent angles formed by two intersecting lines. They must add up to 180°.
Corresponding angles: They are angles that occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are congruent, i.e., they have the same measure.
The figure shows two parallel lines a and b, crossed by the line m. These conditions make the following relations be true:
Angles 3 and 4 are linear pair
Angles 8 and 4 are corresponding.
The first relation leads to:
[tex]m\angle 3+m\angle 4 = 180^\circ[/tex]
The second relation leads to:
[tex]m\angle 4 = m\angle 8[/tex]
Since:
[tex]m\angle 3=x[/tex]
[tex]m\angle 8=5x[/tex]
Substituting:
[tex]x + 5x = 180^\circ[/tex]
Simplifying:
[tex]6x = 180^\circ[/tex]
Solving for x:
[tex]x = 180^\circ/6[/tex]
[tex]x = 30^\circ[/tex]
Now,
[tex]m\angle 3=x=30^\circ[/tex]
[tex]m\angle 8=5x=150^\circ[/tex]
[tex]m\angle 3=30^\circ,~m\angle 8=150^\circ[/tex]

Please explain how to find the angle
We are given:
A right angled triangle with Perpendicular = 16 and base = 11
∠A = θ
Finding θ:
Using basic trigonometry, we know that Tanθ = Opposite / Adjacent
replacing the values for the angle θ
Tanθ = 11 / 16
[since 11 is the opposite side and 16 is the adjacent side to the angle]
θ = ArcTan(11/16)
θ = 34.5° OR 0.6 radians
