Fill in the missing angles if angle 1 is 125 degrees. Remember: vertical angles are equal and supplementary angles add to 180 degrees.
Answers
. 5 and 4 are supplementary angles so it’s adds up to 180 that why you subtract 125 from 180 to get the missing number. 7 and 4 are vertical angles so they equal the same.
Answer:
See below
Step-by-step explanation:
Good work so far
1 = 4 so each are 125 degrees
We know that horizontal lines equal 180 degrees so:
125 + angle 3 = 180
180 - 125 = angle 3
angle 3 = 55
angle 3 = angle 2
so angle 2 is 55 as well
If we look at the angles below, they are the exact same as the angles above, therefore we can say that:
1 = 4 = 5 = 8
2 = 3 = 6 = 7
angle 6 and 7 = 55

Answers
The distance around the outer circle of the water is 14π. Option B shows the correct circumference of the circle.
In geometry, circumference is the circumference of a circle or an ellipse. That is, the circumference will be the length of the arc of the circle as if it were opened and straightened into a line segment. More generally, the perimeter is the length of the curve around any closed figure. The circumference can also refer to the circle itself, which corresponds to the path of the edge of the disc. The circumference of a sphere is the circumference or length of one of its great circles.
Given Information:
A lawn sprinkler sprays water 7 feet in every direction as it rotates.
When the sprinkler covers all directions, it completes its one revolution of the circle. The distance around the outer circle of the water is calculated by the perimeter of the circle which is called the circumference of the circle.
Circumference = 2πr
Where r is the radius of the circle = 7 feet.
Circumference = 2π × 7
⇒ Circumference = 14π
Hence we can conclude that the distance around the outer circle of the water is 14π. Option B shows the correct circumference of the circle.

On a postsynaptic membrane, the opening of which ion channel(s) induces an IPSP? Why? VRest -70 mV, threshold = -55 mV, Ec= -63 mV, Ex = -90 mV, and ENa = 60 mV. a) K+; It hyperpolarizes the neuron. O
Answers
On a postsynaptic membrane, the opening of K+ ion channel induces an IPSP (Inhibitory Postsynaptic Potential).
The potential changes in a neuron after the receptor and ion channel activation is called synaptic potential. This potential can be either an Excitatory Postsynaptic Potential (EPSP) or an Inhibitory Postsynaptic Potential (IPSP).EPSP is a depolarizing potential that results from the opening of the Na+ ion channel. It causes a change in the potential of the neuron towards threshold level that may trigger an action potential.Ion channels and pumps in a postsynaptic neuron regulate the internal potential of the cell. In a typical postsynaptic cell, the resting potential (Vrest) is -70 mV, the threshold value is -55 mV, the reversal potential for Cl- ion (Ec) is -63 mV, the reversal potential for K+ ion (Ex) is -90 mV, and the reversal potential for Na+ ion (ENa) is 60 mV.The opening of Cl- ion channel leads to an inward flow of negative ions and thus results in hyperpolarization. The opening of K+ ion channel leads to an outward flow of K+ ions, and the membrane potential becomes more negative. Thus, it also results in hyperpolarization. The opening of a Na+ ion channel leads to inward flow of Na+ ions, which makes the cell more positive, and it is depolarization. Therefore, the opening of K+ ion channel leads to an IPSP, and it hyperpolarizes the neuron.
The postsynaptic potential can be either an Excitatory Postsynaptic Potential (EPSP) or an Inhibitory Postsynaptic Potential (IPSP). The opening of the K+ ion channel leads to an outward flow of K+ ions, which makes the cell more negative and hyperpolarizes it, leading to IPSP.

a spherical golf ball is measured to have a radius of $$5 mm, with a possible measurement error of $$0.1 mm. what is the possible change in volume? use differential to estimate the error when computing the volume.
Answers
The possible change in volume (in mm3) resulting from the error in measuring the radius is 32. 06 mm³
Given,
A spherical golf ball is measured to have a radius of $$5 mm, with a possible measurement error of $$0.1 mm
How to determine the volume
The formula for volume of a sphere is expressed by;
Volume = 4/3 πr³
Where;
r is the radius of the sphere
pi takes the value 3.14
From the information given, we have that the measured radius is 5 mm, with a possible measurement error of 0.1 mm
Then, radius a = 5mm
Radius b = 5 + 0. 1 = 5. 01mm
Now, substitute the values into the formula
Volume, v = 4/ 3 (3.14)(5)³
v = 4/ 3 (392.5)
v = 523. 3 mm³
For radius of 5.01mm
Volume = 4/ 3 (3.14)(5.1)³
expand the bracket
Volume = 4/3 (416.52)
Volume = 555. 4 mm³
The change in volume = 555. 4 - 523. 3 = 32. 06 mm³

Answers
If about 20% of British children are deficient in vitamin and doctors test a group of elementary school children, the probability that the first vitamin d-deficient child is the 8th one tested is 4.19% determined using geometric distribution formula.
In probability and statistics, geometric distribution refers to the probability that first success would occurs after n number of trials and is given by:
P(X)=q^(x-1)p
Where p is the probability of success and q is (1-p)
In this case,
p=probability of children deficient in vitamin= 0.2
q= probability of children not deficient in vitamin= 0.8
Hence,
P(8)=0.8^(8-1)*0.2= 0.0419

Answer: I recommend starting treatment immediately. If you take more than 8 days to make a decision, the disease can no longer be cured because it will affect more than 50% of the body.
Step-by-step explanation:
The percentage of the body affected by the disease is a function of the number of days:
P(d) = 6d + 5This percentage is a dependent variable and the number of days is the independent variable.
If we give values to d, we can calculate the percentage of the body affected by the disease.
P(1)= 6·1 + 5 = 11%
P(2)= 6·2 + 5 = 17%
P(3)= 6·3 + 5 = 23%
P(4)= 6·4 + 5 = 29%
P(5)= 6·5 + 5 = 35%
P(6)= 6·6 + 5 = 41%
P(7)= 6·7 + 5 = 47%
P(8)= 6·8 + 5 = 53%
Depending on the days since the beginning of the disease, the doctors have a treatment for a different stage.
Starting immediately, the treatment will be stage 1: less than 15%
Starting on day 2 or 3, the treatment will be stage 2: 15-25%
After day 3, the treatment will be stage 3: 25-50%
After day 8, there is no cure: more than 50% of the body is affected by the disease.
I recommend starting treatment immediately. If you take more than 8 days to make a decision, the disease can no longer be cured because it will affect more than 50% of the body.

Determine whether the statement below is true or false. If it is false, explain. Least squares means that the square of the largest residual is as small as it could possibly be. Choose the correct answer below. O A. The statement is false. It is the sum of the squares of all the residuals that is minimized. OB. The statement is true. O C. The statement is false. It is the difference of the squares of all the residuals that is minimized.
Answers
C. The statement is false. It is the sum of the squares of all the residuals that is minimized.
In the context of least squares, the goal is to minimize the sum of the squares of the residuals, not the square of the largest residual alone. The residuals are the differences between the observed values and the corresponding predicted values obtained from a regression model.
By minimizing the sum of the squares of the residuals, the least squares method ensures that all residuals contribute to the overall measure of fit, rather than just focusing on the largest residual. This approach provides a balanced and comprehensive assessment of the overall goodness of fit between the model and the observed data.
Therefore, the statement that the square of the largest residual is as small as it could possibly be is false. The least squares method aims to minimize the sum of the squares of all the residuals, leading to the best overall fit between the model and the data.
