How do you know when to use the less than symbol and when to use the less than or equal to symbol when writing an inequality for a situation?
Answer:
This depends on the situation. For context, you use less than when your inequality CANNOT exceed more than.
You would use less than or equal to if your inequality can be equal to a number. Here's an example.
John needs to buy X oranges and Y apples. He can AT MOST buy 10 total fruits.
x + y (equal to or less than) 45
John needs to buy X oranges and Y apples. He CANNOT buy more than 10 total fruits.

A square has side length 3 units. What is the length of the diagonal?
9514 1404 393
Answer:
C. 3√2 units
Step-by-step explanation:
The diagonal of a square is √2 times the side length. For a square with side length 3, the diagonal is 3√2.
__
If you like, you can see this using the Pythagorean theorem.
d² = s² + s² . . . . . where d is the diagonal, and s is the side
d² = 2s²
d = √(2s²) = s√2
For s=3, ...
d = 3√2

If the outside diameter of a pipe is 1.275 feet and the inside diameter is 0.975 feet how thick is the pipe
Answer:
2.250 feet thick
Step-by-step explanation:
hope it helps mark as brainliest
Answer:
Step-by-step explanation:
The outside diameter minus the inside diameter would leave a difference of TWICE the thickness of the pipe, so divide the difference by 2
Pipe Thickness = (OD - ID) / 2
= (1.275 - 0.975) / 2
= 0.3 / 2
= 0.15 feet

Find the surface area of the net below.
Step-by-step explanation:
Area of 4 triangles = 1/2 x base x height
[tex] =4 \times \frac{1}{2} \times 7 \times 5 \\ = 2 \times 7 \times 5 \\ = 14 \times 5 \\ = 70 {m}^{2} [/tex]
Area of middle square = Length x Width
[tex] = 7 \times 7 \\ = 49 {m}^{2} [/tex]
Surface Area = Area of 4 triangles + Area of middle square =

Determine the amount of time it will take for Daniel and
for Brandon to get to the taco truck.
Use paper and/or a calculator as necessary,
Answer:
Daniel = 207 | Brandon = 196.2
Step-by-step explanation:
Brandon will reach the taco truck first.
• Daniel's time can be found by using the expression 327.6/3 + 489/5, which is 207 seconds.
• Brandon's time can be found by using the expression
327.6^+489^2/3 [Sqaured]
The time taken by Brandon will be 196.2 seconds while Daniel will be 207 seconds.
What is a triangle?A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices.
In a triangle, the sum of all three angles is 180°.
⊕ Time is taken by Brandon ;
01) Time taken in sand
Time = 327.6/3 = 109.2 seconds.
02) Time is taken on the boardwalk
Time = 489/5 = 97.8 seconds.
Total time taken by Brandon = 109.2 + 97.8 = 207 seconds.
⊕ Time is taken by Daniel;
By Pythagoras theorem
Distance by Daniel = √(327.6² + 489² ) = 588.60 feets.
Time = 588.60/3 = 196.2 seconds.
So the time taken by Brandon will be 207 seconds and Daniel will be 196.2 seconds.

OMG HELP PLSSS!!/ Each cube in the figures below is one cubic unit. Which figure does not have a volume of 48 cubic units? Select all that apply. A. Rectangular prism with length of 8 feet, width of 2 feet, and height of 3 feet. B. Rectangular prism with length 6 feet, width of 2 feet and height of 4 feet. C. Rectangular prism with length of 4 feet, width of 4 feet and height of 4 feet. D. Rectangular prism with length of 11 feet, width of 2 feet and height of 2 feet.
Answer:
C & D
Step-by-step explanation:
A. = 48 cubic units
B. = 48 cubic units
C. = 64 cubic units
D. = 44 cubic units
The only rectangular prism that does not have a volume of 48 cubic units is C and D, which has a volume of 64 and 44 cubic feet respectively.
What is prism?A prism is a three-dimensional solid object with two identical ends. It is made up of flat faces, identical bases, and equal cross-sections. The prism's faces are parallelograms or rectangles without bases.
To find the volume of each rectangular prism, you can use the formula V = lwh, where V is the volume, l is the length, w is the width, and h is the height.
Rectangular prism with length of 8 feet, width of 2 feet, and height of 3 feet.
V = (8)(2)(3) = 48 cubic feet
Rectangular prism with length 6 feet, width of 2 feet and height of 4 feet.
V = (6)(2)(4) = 48 cubic feet
Rectangular prism with length of 4 feet, width of 4 feet and height of 4 feet.
V = (4)(4)(4) = 64 cubic feet
Rectangular prism with length of 11 feet, width of 2 feet and height of 2 feet.
V = (11)(2)(2) = 44 cubic feet
Thus, the only rectangular prism that does not have a volume of 48 cubic units is C and D.

Solve the following quadratic equation for all values of x in simplest form. 4(3x - 5)^2+5 = 13 (will give brainly)
Answer:
Step-by-step explanation:
4(3x-5)^2+5=13
4(3x-5)^2+5-13=0
As (a-b)^2=a^2-2ab+b^2
4((3x)^2-2(3x)(5)+(5)^2)-8=0
4(9x^2-30x+25)-8=0
36x^2-120x+100-8=0
36x^2-120x+92=0
using the Quadratic Formula where
a = 36, b = -120, and c = 92
x=(−bc± sqrt(b^2-4ac))/2a
x=(-(-120)±sqrt((−120)^2−4(36)(92))/2(36)
=120±sqrt(14400−13248−)/72
=120±sqrt(1152)/72
The discriminant b2−4ac>0
so, there are two real roots.
x=(120±24sqrt(2))/72
x=(120/72)±24sqrt(2)/72
implify fractions and/or signs:
x=5/3±sqrt(2)/3
hich becomes
x=2.13807
x=1.19526
Lilly was working on a report on Italian and Spanish scientists. She decided to find a 96 percent confidence interval for the difference in mean age at the time of significant scientific discoveries for Italian versus Spanish scientists. She found the ages at the time of science discovery of all the members of both groups and found the 96 percent confidence interval based on a t-distribution using a calculator. The procedure she used is not appropriate in this context because
The entire population is measured in both cases, so the actual difference in means can be computed and a confidence interval should not be used.
The sample sizes for the two groups are not equal.
Age at the time of science discovery occurs at different intervals in the two countries, so the distribution of ages cannot be the same.
Age at the time of science discovery is likely to be skewed rather than bell shaped, so the assumptions for using this confidence interval formula are not valid.
Age at the time of science discovery is likely to have a few large outliers, so the assumption for using this confidence interval formula is not valid.
A t statistic was used to conduct a test of the null hypothesis H0: µ = 11 against the alternative Ha: µ ? 11, with a p-value equal to 0.042. A two-sided confidence interval for µ is to be considered. Of the following, which is the largest level of confidence for which the confidence interval will NOT contain 11?
A. A 90% confidence level
B. A 92% confidence level
C. A 96% confidence level
D. A 97% confidence level
E. A 98% confidence level
Answer:
The answer is "Option A and Option B".
Step-by-step explanation:
In question 1:
In all cases, the entire population is measured so that the actual medium discrepancy could be measured as well as an interval of trust cannot be used.
This issue would be that she calculated the ages with all representatives of both classes, such that she measured a whole population. It's not necessary.
In question 2:
When the p-value is 0.042. At 90% trust and 92% trust level 11 (p-value below 0.10 and 0.08) are not included. however the biggest confidence level of 92%. Consequently, the largest trust level where the 11 is Not included in the trust interval is 92% trust.
