128 * [tex]\frac{5}{8}[/tex] = 80
Answer:
80
Step-by-step explanation:
let's look at the probability. There is a 5/8 chance of the spinner landing on an odd number. you would multiply the 128 by 5/8 to get your estimate of 80 times the spinner will land on an odd number. Hope this helps! :)
1a. [1 mark] The price per kilogram of tomatoes, in euros, sold in various markets in a city is found to be normally distributed with a mean of 3.22 and a standard deviation of 0.84. Find the price that is two standard deviations above the mean price.
Answer:
The price that is two standard deviations above the mean price is 4.90.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 3.22 and a standard deviation of 0.84.
This means that [tex]\mu = 3.22, \sigma = 0.84[/tex]
Find the price that is two standard deviations above the mean price.
This is X when Z = 2. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]2 = \frac{X - 3.22}{0.84}[/tex]
[tex]X - 3.22 = 2*0.84[/tex]
[tex]X = 4.9[/tex]
The price that is two standard deviations above the mean price is 4.90.

For most questions asking for the area of a part of a figure, you first have to find the area of the figure then divide to get the part. Because the water level is 2/3 up, we can divide by 3 and that would make it the needed 1/3.
Volume of a rectangular prism: L*W*H
3 3/4 * 3 3/8 * 13 1/3
Becomes
168 3/4
Then divide by 3
56 1/4
or
56.25
Answer:
v = 56.25ft³
Step-by-step explanation:
Total volume
v = 3 3/4 * 13 1/3 * 3 3/8
v = 15/4 * 40/3 * 27/8
v = 16200 / 96
1/3 without water
v = (16200 / 96) * (1/3)
v = 16200 / 288
v = 56.25ft³

The y- intercept is 3.
What is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
18x−6y=12
Writing the above equation in slope- intercept form
6y = 18x - 12
y= 18x /6 - 12/ 6
y= 3x - 2.
So, the slope of perpendicular line is -1/3 and passes through (6, 1)
y= mx+ c
1 = -1/3 (6) + c
1 = -2 + c
c= 3
Hence, the y- intercept is 3.

Gabriel is playing a board game. When it is his turn, he tosses a three-dimensional figure that has 6 square faces. What kind of figure is it? How many edges and vertices does it have? Draw the figure to support your answer
Answer:
Quadrilaterally-faced hexahedron
12 edges and 8 vertices
Step-by-step explanation:
This would be a regular dice which is used in the vast majority of board games that exist. The shape of this is formally known as a Quadrilaterally-faced hexahedron, also known as a cuboid. There are various versions of a hexahedron such as a Rectangular cuboid or a Rhombohedron, one of which has rectangular faces and the other has rhomboid faces. The hexahedron has 12 edges and 8 vertices in total

HELPP!! The transformation functions R, S, T, U, and V are shown below
Answer:
Point T(x, y) is translated 71 units up and then rotated 180° about the origin
Point U(x, y) is rotated 90° counterclockwise, then translated 124 units up.
Point V(x, y) is reflected about the y axis, then translated 8831 units to the left.
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
If a point R(x, y) is vertical stretched by a factor of 38 followed by a horizontal stretch of 7, the new point is at R'(x/7, 38y). That is (x, y) ⇒ (x/7, 38y).
If a point S(x, y) is translated 9 units to the right, the new point is (x + 9, y), if it is reflected over the y axis, the new point is S'(-x-9, y). That is (x, y) ⇒ (-x-9, y).
If a point T(x, y) is translated 71 units up, the new point is at (x, y + 71), if it is rotated 180° about the origin, the new point is at T'(-x, -y - 71). That is (x, y) ⇒ (-x, -y - 71).
If a point U(x, y) is rotated 90° counterclockwise, the new point is at (-y, x), if it is then translated 124 units up, the new point is U'(-y, x + 124).
If a point V(x, y) is reflected about the y axis, the new point is at (-x, y), if it is then translated 8831 units to the left, the new point is V'(-x - 8831, y).

What is the y-coordinate of point C?
OA A
OB. -5
Oc. -6
OD. -7
Answer:
[tex]y = -5[/tex]
Step-by-step explanation:
Given
[tex]B = (7,-3)[/tex]
[tex]C = (6,y)[/tex]
[tex]A = (4,-9)[/tex]
Required
The y coordinate of C
Since A, B and C are on the same line, the slope of AB and the slope of AC will be the same.
Slope (m) is calculated as:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
For AC
[tex]A = (4,-9)[/tex] [tex]C = (6,y)[/tex]
[tex]m = \frac{y - -9}{6 - 4}[/tex]
[tex]m = \frac{y +9}{2}[/tex]
For AB
[tex]A = (4,-9)[/tex] [tex]B = (7,-3)[/tex]
[tex]m = \frac{-3 --9}{7-4}[/tex]
[tex]m = \frac{-3 +9}{3}[/tex]
[tex]m = \frac{6}{3}[/tex]
[tex]m = 2[/tex]
So, we have:
[tex]m = \frac{y +9}{2}[/tex] and [tex]m = 2[/tex]
[tex]m = m[/tex]
[tex]\frac{y +9}{2} = 2[/tex]
Multiply both sides by 2
[tex]y +9 = 4[/tex]
Solve for y
[tex]y = 4-9[/tex]
[tex]y = -5[/tex]
Hence, the y coordinate of C is -5
