Answer:
Ca (Calcium)
Explanation:
Calcium is a positive ion with a charge of 2+. The metal is also an alkali earth metal since the oxide MO is basic when dissolved in water.
In light of the preceding circumstances;
The metal is not arsenic since arsenic is a metalloid with the oxides As2O3 and As3O5, which are amphoteric (reactive as both, a base and/or acid) and acidic in nature, respectively.
Because it is a metalloid, the metal is not germanium, and even though germanium oxide has the formula GeO2, it is amphoteric.
Because chlorine is a non-metal, the metal is not chlorine.
Because calcium oxide has the formula CaO and calcium is an alkaline earth metal, the metal is unmistakably calcium.
Because selenium is anon-meal and its oxide has the formula Se02 and is acidic, the metal is not selenium.
Corey deposited $700 into a savings account that pays a simple annual interest rate of 2. 9%. How much interest will he earn after 3 months?
The simple interest that Corey will earn after 3 months is $5.075
What is simple interest?Simple interest is a calculation of interest that doesn't take into account the effect of compounding.
The simple interest (SI) is computed as :
= p * r * t / 100
= 1 / 100 ( 700 * 2.9 * 3 / 12 )
= 7 * 2.9 * 1 / 4
= 5.075
Hence, the simple interest that Corey will earn after 3 months is $5.075

How career and study choices are influenced by availability of finances/affordability
There are several elements that might impact a person's profession decision. This decision-making process begins when high school graduates decide on the degree they want to pursue while keeping their budget in mind. A college degree is a valuable commodity that many young folks want to get, but it is also growing increasingly expensive. Many students choose a more cheap and practical degree over what they actually want to study because of economic considerations. In truth, college affordability is a catastrophe that the United States is currently confronting. According to the College Board, students at public universities spend more than $20,000 on tuition and room and board alone during the course of a four-year degree. As a result of the crisis, many students are obliged to pursue less costly occupations, which means they must take less expensive degree programs. The cost of receiving a higher education might impact an individual's study choices and, as a result, his or her future employment choices.

A doctor is measuring the mean systolic blood pressure of female students at a large college. Systolic blood pressure is known to have a skewed distribution. The doctor collects systolic blood pressure measurements from random sample of 28 female students. The resulting 90% confidence interval is (100. 4, 159. 6). Units of systolic blood pressure are mmhg. Which one of the following conclusions is valid?
Using the Central Limit Theorem, it is found that the valid conclusion is given as follows:
The sampling distribution will probably not follow a normal distribution, hence we cannot draw a conclusion.
Central Limit TheoremThe Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the sampling distribution is also approximately normal, as long as n is at least 30.
In this problem, we have a skewed variable with a sample size less than 30, hence the Central Limit Theorem cannot be applied and the correct conclusion is:
The sampling distribution will probably not follow a normal distribution, hence we cannot draw a conclusion.

Do you think evil exists? Is there an ultimate cause of evil? If there is an ultimate cause of the good (for example, God) and an ultimate cause of evil (for example, the Devil), which ultimate cause is greater? How do you know? If God exists and God is good, then why does God allow evil in the world? Can God design a world without suffering? If God is dead or does not exist, does this mean that evil will take over the world? Can good exist without God? Are humans free to do evil acts if they have free will? If yes, then is giving humans free will in fact an evil act? Can a person be evil while going good deeds?
Answer:
Evil people don't exist, but evil actions do.
Explanation:
No one can be born completely evil, but they could have done evil things. There isn't one cause of evil, rather, there are many and they vary. An example of one could be massacre ten people because those people killed their child, or friend, or relative of some sort. While it isn't right, there is usually motives. Someone who has hunger for human flesh will kill humans to eat them. It also isn't right, but the hunger is the motive, not the main drive of the person. I don't think God and the Devil exist, but if they did, God could not create a world without suffering. It is impossible to watch everything at once and if God helped us too much, we'd be helpless to defend ourselves and we could not function or advance without God's help. Good can exist without God, because there are always good people out there. Humans are free to do evil acts if they have free will, but that doesn't mean everyone would do evil acts. Giving humans free will is not an evil act, it's like giving lifeless puppets life and watching them. Refusing humans free will is also an evil act, it is basically like slavery. Yes, a person could be evil while doing good deeds because like I said, no one is completely evil.

Answer:
ω = 13.33 rad/sExplanation:
Applying,
v = ωr......................... Equation 1
Where v = linear speed, ω = angular speed and r = radius.
Note that,
r = d/2................. Equation 2
Where d = diameter of the wheel.
Substitute equation 2 into equation 1
v = ωd/2............... Equation 3
make ω the subject of the equation
ω = 2v/d................ Equation 4
Given: v = 4 m/s, d = 60 cm = 0.6 m
Substitute these values into equation 4
ω = 2(4)/0.6

A typical neutron star has a mass of about 1. 5msun and a radius of 10 kilometers
How thick a layer would Earth form as it wraps around the neutron star’s surface is: 6.67 10⁻³ m.
Density of the Neutron starDensity
ρ = m / V
Where:
ρ= density
m = mass of the planet 5.98 10²⁴ km
V =volume of the spherical layer
Volume of a sphere
Volume = 4/3 π r³
Mass = 1.5 = 1.5 1,991 10³⁰
Mass= 2.99 10³⁰ kg
Density:
ρ = 2.99 10³⁰ / [4/3 π (10 10³)³]
ρ is = 7.13 10 17 kg / m³
V = 5.98 10²⁴ / 7.13 10¹⁷
V = 8,387 10⁶ m³
Thickness of the layer
V = 4π r² e
e = V / 4π r
e = 8,387 10⁶ / [4π (10 10³)²]
e = 6.67 10⁻³ m

Answer:
A 0.32
Explanation:
i got it right
The approximate measure of an angle is calculated as 0.32 radian. Thus, the correct option for this question is found to be A.
What do you mean by Trigonometric functions?Trigonometric functions may be characterized as those functions that are actual and tangible in all respective forms. They simply function as the angle of a triangle. The three basic and most fundamental trigonometry functions may include Sine, Cosine, and Tangent.
According to the context of this question,
We have a right-angled triangle and require to find the angle L. This is found with help of the Tangent of an angle in a right-angled triangle. It is the respective ratio of the opposite side to the adjacent side.
The height of a pole = 9.5 feet.
The height of the shadow which is formed = 29 feet.
tan L = JK / LK
tan L = 9.5 / 29
L = tan⁻¹ (9.5 / 29)
L = 0.31657 radians ≅ 0.32 radians.
Therefore, the approximate measure of an angle is calculated as 0.32 radian. Thus, the correct option for this question is found to be A.
