What is the value of the expression below when n=5
Answer:
-6 (i can explain if its needed)
Step-by-step explanation:
[tex]2 - {n}^{2} + 3 \times 14 - {n}^{2} = \\ 2 - {n}^{2} + 42 - {n}^{2} = \\ 2 - 25 + 42 - 25 = - 6[/tex]
Lunches can be made consisting of exactly one entrée, one drink, and one snack. If all lunch options are equally likely, what is the probability of randomly choosing a lunch that
does not contain the veggie wrap
has milk or water, and
has fruit as the snack.
Write your answer as a percentage, to the nearest percent.
Entrée Chicken Cutlet Veggies Wrap Lasagna
Drink Milk Water Iced Tea
Snack Fruit Chips Jello
%
Answer:
4/27=14.8%
Step-by-step explanation:
In order to solve this, we have to see first each option possible, there are 2/3 of possibilities that a random Entrée ends up being Chicken Cutlet or Lasagna, then you have again 2/3 chances to get milk or water, and as you only want fruit the chances are 1/3 that you get that.
In order to calculate if this could happen at random we have to multiply all of the odds:
[tex]Probability: \frac{2}{3} *\frac{2}{3} *\frac{1}{3} \\Probability: \frac{2*2*1}{3*3*3} \\Probability: \frac{4}{27}[/tex]
So we know that for every 27 times you pick a lunch at random, 4 times it will not have the Veggie Wrap, contain milk or water, and will have fruit as the snack.
There are 2/3 of possibilities that a random Entrée ends up being Chicken Cutlet or Lasagna, then you have again 2/3 chances to get milk or water, and as you only want fruit the chances are 1/3 that you get that.
We need to now multiply the odds:
2/3x2/3x1/3
2x2x1/3x3x3
4/27
So we know that for every 27 times you pick a lunch at random, 4 times it will not have the Veggie Wrap, contain milk or water, and will have fruit as the snack.
So now we know it is, %15 rounded but 14.8% not rounded.
The original price of a scarf was $25. During a store-closing sale, a shopper saved $15 on the scarf. 1. What percentage discount did she receive? Type the answer in the box below. She received a % discount.
Answer:
there was a 60 percent discount on the scarf
Answer:
60%
Step-by-step explanation:
How I did it is I put 15 over 25 and multiplied it by x over 100.
It should look like this
15/25 x x/100
which 15 multiplied by 100 is 1500 and then 1500 divided by 25 is 60

Sophie found the volume of the figure below by using the steps shown.
A rectangular prism with a length of 28 millimeters, width of 21 millimeters, and height of 4 millimeters. A rectangular pyramid with a base of 28 millimeters by 21 millimeters and height of 26 millimeters.
Total Volume = B h + one-third B h = 4 (21) (28) + one-third (21) (28) (30) = 2,352 + 5,880 = 8,232 cubic millimeters.
What mistake, if any, did Sophie make?
Sophie determined the volume correctly.
Sophie used the wrong formula for the total volume.
Sophie used the wrong height for the pyramid.
Sophie did not apply the order of operatio
Answer:
(C) Sophie used the wrong height for the pyramid.
Step-by-step explanation:
she should have subtracted 4 from 30 because that was apart of the prism
The total volume is 7448 cubic millimeters. Sophie has made mistake in copying height of pyramid.
What is the volume?Volume is the measure of the capacity that an object holds.
Formula to find the volume of the object is Volume = Area of a base × Height.
Given that, a rectangular prism with a length of 28 millimeters, width of 21 millimeters, and height of 4 millimeters.
Volume of rectangular prism = Length×Width×Height
= 28×21×4
= 2352 cubic millimeters
A rectangular pyramid with a base of 28 millimeters by 21 millimeters and height of 26 millimeters.
Volume of a rectangular pyramid = (lwh)/3
= (28×21×26)/3
= 15288/3
= 5096 cubic millimeters
Total volume = 2352+5096
= 7448 cubic millimeters
Hence, Sophie has made mistake in copying height of pyramid.

The length of a boat is 10.8 metres. Boris buys a scale model of the boat. The scale of the model is 1/18 Work out the length of the scale model of the boat. Give answer in centimetres
Answer: 60 cm
Step-by-step explanation:
The actual length of the boat is 10.8 meters.
The scale model length is 1/18 of the actual boat.
Length of scale model will therefore be:
= 10.8 * 1/18
= 0.6 meters
A meter is 100 centimeters.
= 0.6 * 100
= 60 cm

need help with geometry
Answer: 55 degrees
Step-by-step explanation:
so we only need to focus on the triangle with m<1 we know that it is a right triangle so there's already 90 degrees.
if we do 180 - 145 that gives us another angle measurement which is 35
now to find angle 1 we need to add 90 + 35 = 125
since there's 180 degrees in a triangle we do 180 - 125 and that gives us 55 which is the missing angle

Answer:
24.6 Nm north67.7 Nm westStep-by-step explanation:
In x-y coordinates, the direction is 70° CCW from 90° (north), so is 160° from the +x axis. In 4 hours at 18 Nm/h, the ship will travel 4×18 Nm = 72 Nm.
The coordinates in the x-y plane can be found to be ...
72(cos(160°), sin(160°)) ≈ (-67.7, 24.6)
The ship traveled 67.7 nautical miles west and 24.6 nautical miles north from the port.

When x = 4, the value of y that is missing is 16.
When x equals 6, the value of y is 24.
The graph shows a linear connection.
Given is a table of values of x and y,
x = 1, 2, 3, 4, 5
y = 4, 8, 12, ?, 20
We need to find the missing value of y corresponding to x = 4, the nature of the graph and the value of y when x = 6.
To find the missing value of y corresponding to x = 4, we can observe the pattern in the given values.
From the given values, we can see that the relationship between x and y is a linear one, where the value of y increases by 4 for each unit increase in x.
To find the missing value of y when x = 4, we can use this linear relationship.
Since y increases by 4 for each unit increase in x, we can calculate:
y = 4 + (4 × (x - 1))
Substituting x = 4 into the equation:
y = 4 + (4 × (4 - 1))
y = 4 + (4 × 3)
y = 4 + 12
y = 16
So, the missing value of y corresponding to x = 4 is 16.
Now, to find the value of y when x = 6, we can use the same linear relationship:
y = 4 + (4 × (x - 1))
Substituting x = 6 into the equation:
y = 4 + (4 × (6 - 1))
y = 4 + (4 × 5)
y = 4 + 20
y = 24
Therefore, when x = 6, the value of y is 24.
In summary:
The missing value of y when x = 4 is 16.
The value of y when x = 6 is 24.
The nature of the graph is a linear relationship.
