Maria makes a fruit salad. The table shows the amounts of different kinds of fruit that she uses.
Answers
To be able to determine how many cups of strawberries does Maria use, we will be using the given clue regarding the number of strawberries she uses for the salad.
"The amount of strawberries that Maria uses is 3/8 times the amount of the other fruits combined."
From that, we generate this computation for the number of strawberries:
\(\text{ Amount of Strawberries = }\frac{3}{8}(Grapes\text{ + Melon + Pineapple)}\)We get,
\(\text{ Amount of Strawberries = }\frac{3}{8}(Grapes\text{ + Melon + Pineapple)}\)\(\text{ Amount of Strawberries = }\frac{3}{8}(3\frac{2}{3}\text{ + 2}\frac{1}{4}\text{ + 2}\frac{3}{4})\)\(\text{= }\frac{3}{8}(\frac{11}{3}\text{ + 5)}\)\(\text{= }\frac{3}{8}(\frac{11}{3}\text{ + }\frac{15}{3}\text{) = }\frac{3}{8}(\frac{11\text{ + 15}}{3})\)\(\text{ = }\frac{3}{8}(\frac{26}{3})\)\(\text{ = }\frac{78}{24}\)\(\text{ = }\frac{13}{4}\text{ or 3 1/4}\)Therefore, Maria uses 3 1/4 cups of strawberries in making the salad.

The sales tax for an item was 15.20 and it cost 380 before tax.
Find the sales tax rate. Write your answer as a percentage.
Answers
If the sales tax for an item was 15.20 and it cost 380 before tax. the sales tax rate is: 4%.
How to determine the sales tax ?Using this formula
Sales tax rate = Item sales tax / Cost before tax
Where:
Item sales tax = 15.20
Cost before tax = 380
Let plug in the formula
Sales tax rate = 15.20 / 380 × 100
Sales tax rate = 4%.
Therefore the tax rate is 4%

find the bearing of a from b
find the bearing of b from a
Answers
Answer:
130° and 310°
Step-by-step explanation:
the bearing of A from B is the measure of the clockwise angle from a north line at B to A
the angle at B and A are same- side interior angles and sum to 180°
angle at B = 180° - 50° = 130°
the bearing of A from B is then 130°
the bearing of B from A is the measure of the clockwise angle from the north line at A to B
the complete angle about A = 360° then clockwise angle from north line at A to B is
360° - 50° = 310°
the bearing of B from A is 310°

Answers
The images best represents the result is image W.
We have, the image is rotated about the x-axis.
Now, rotating around x axis can give the other half of the image.
Also, rotating about x axis gives the mirror image of the figure.
So, the rotation leads to a circle.

Answers
Based on the information, both ∧ (conjunction) and ∨ (disjunction) satisfy the commutative property.
How to explain the commutative property.It should be noted that to prove the commutativity of the logical connectives ∧ (conjunction) and ∨ (disjunction), we need to show that they satisfy the commutative property
From the truth table, both P ∧ Q and Q ∧ P have the same truth values for all combinations of truth values of P and Q. Therefore, we can conclude that P ∧ Q ≡ Q ∧ P, and ∧ (conjunction) is commutative.
In order to prove P ∨ Q ≡ Q ∨ P, we construct a truth table for both expressions. Both P ∨ Q and Q ∨ P have the same truth values for all combinations of truth values of P and Q. Therefore, we can conclude that P ∨ Q ≡ Q ∨ P, and ∨ (disjunction) is commutative.
Hence, both ∧ (conjunction) and ∨ (disjunction) satisfy the commutative property.

Researchers are investigating the effect of pH level in water on the breeding habits of the moon jellyfish. As part of a laboratory experiment, they will randomly assign one of three treatments, low pH, medium pH, or high pH, to the water in the tanks that hold the jellyfish.
Which of the following is the best reason for the random assignment of a treatment level to an experimental unit?
Answers
Answer:
A. Randomization tends to minimize the effects of uncontrolled variables, such as water temperature, so that such factors are not confounded with the treatment effects.

Which of the following is the best reason for the random assignment of a treatment level to an experimental unit?
A. Randomization tends to minimize the effects of uncontrolled variables, such as water temperature, so that such factors are not confounded with the treatment effects.
B. Randomization will make up for improper experimental design, data collection, and analysis.
C. Randomization makes the analysis easier since the data can be entered into the computer in any order.
D. Randomization is required by statistical consultants before they will analyze the experiment.
E. Randomization means that the experiment would not need to be replicated---
Randomization is used to ensure that the results of a trial or an experiment are actually because if the treatment or hypothesis we are trying, instead of any other external factor that we can not control, or because it just always happens that way, if all of the jellyfish are affected or not in the same way, then the Ph had little to nothing to do with it, and if only one group of them is affected we can re-try the experiment to see if the difference in the Ph had anything to do with the change.

A.Randomization tends to minimize the effects of uncontrolled variables, such as water temperature, so that such factors are not confounded with the treatment effects.

Use the Pythagorean theorem to find the distance between points P and Q
Answers
The distance between the points P and Q is 10 units using the Pythagorean theorem.
What is Pythagoras Theorem?The right-angled triangle's three sides are related in accordance with the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagorean theorem states that the hypotenuse square of a triangle is equal to the sum of the squares of the other two sides. According to the Pythagoras theorem, if a triangle has a right angle, the hypotenuse's square is equal to the sum of the squares of the other two sides.
The coordinates of the point P and Q are (3, 2) and (9, 10).
Using the Pythagoras theorem:
c² = (x2 - x1)² + (y2 - y1)²
Substitute the values:
c² = (9 - 3)² + (10 - 2)²
c² = 36 + 64
c² = 100
c = 10 units.
Hence, the distance between the points P and Q is 10 units using the Pythagorean theorem.
