If the state legislature cannot agree on a state budget, what would MOST LIKELY happen?
State employees would not receive salaries.
A temporary spending authority would be passed.
The governor would suspend the state legislature.
D)
Spending on government services would come to a halt
When a state legislature cannot agree on a state budget, the most probable outcome is the passing of a temporary spending authority, allowing the government to maintain operations while negotiations continue. Other, more drastic measures occur in extreme cases.
Explanation:If the state legislature cannot agree on a state budget, the most likely outcome would be that a temporary spending authority would be passed, also known as a continuing resolution. This temporary resolution authorizes the government to continue operations at the current funding level until a new budget can be agreed upon. Without this, essential government services could be disrupted, including wages for state employees and spending on other government services.
Halting all government spending or suspending the state legislature is highly unlikely and would typically only happen in extreme situations. It's also important to note that the specifics of what happens when a budget isn't passed can vary from state to state, as the processes for managing this situation are defined by each state's constitution and laws.

find the sum of−2 5/10 and−5 4/15. then, in two or more complete sentences, explain the steps you used to add the mixed numbers.
Answer:
- 7 23/30
Step-by-step explanation:
-2 5/10 + -5 4/15
First simplify the fractions if possible
-2 1/2 + -5 4/15
Then, we need to get a common denominator
The common denominator in this case is 30
-2 1/2*15/15 + - 5 4/15*2/2
-2 15/30 + -5 8/30
Since the signs are alike we add
First the whole numbers
2+5 =7
Then the fractions
15/30+8/30 = 23/30
Add the fraction and the whole number together
7 23/30
Take the sign
- 7 23/30
If the fraction was improper, we would change it to a mixed number and add the whole numbers together
Final answer:
To find the sum of −2 5/10 and −5 4/15, convert them to improper fractions, find a common denominator, add them with the negative signs, and simplify if needed, resulting in −7 23/30.
Explanation:
To find the sum of −2 5/10 and −5 4/15, we first convert the mixed numbers into improper fractions. The first step is to add the whole numbers together, and then add the fractions separately.
Since both numbers are negative, when we add them, the answer will also have a negative sign, following the rule that when two negative numbers add, the answer has a negative sign. We find the common denominator for the fractions, which in this case is 30, and convert them accordingly. After adding the converted fractions, we simplify the result if possible.
To illustrate, for the whole numbers: −2 + (−5) = −7. For the fractions: −(5/10 × 3/3) + −(4/15 × 2/2) = −(15/30) + −(8/30) = −(23/30). Thus, the sum is −(7) − (23/30) or −7 23/30.

What is the length of the shortest side of a triangle that has vertices at (4,6), (-2,0), and (-6,3)?
Answer:
5
Step-by-step explanation:
This is a 3, 4, 5 triangle
Answer: 5
If you graphed these three points on a graph you can see that the points (-2,0) and (-6,3) have the smallest length. First we want to find the slope of these points. We can use the formula y2 - y1 / x2 - x1. 3 - 0 / -6 - -2. 3-0 is 3 and -6 - -2 is -4. Two negatives make a postive. So the slope is 3/-4. We can't have a negative slope so change the -4 to a postive 4. Now square the slope 3/4 to get 9 and 16. We know the pythagoren therom formula is a^2 + b^2 = c^2. So square 3 and 4 to get 9 and 16 then add them to get 25. Square 25 and you get the answer 5.

what is the hourly difference in median income for a male versus female with an advanced degree?
The hourly difference in median income between males and females with an advanced degree is approximately $9.62/hr.
To determine the hourly difference in median income between males and females with an advanced degree, we need to know the median income for each gender and the number of hours worked. If you can provide the median income values for both males and females with an advanced degree, I can calculate the difference for you.
For illustration, let's assume the following median income values:
- Median income for males with an advanced degree: M dollars per year
- Median income for females with an advanced degree: F dollars per year
- Average hours worked per week: H hours
- Number of weeks worked per year: W weeks (usually 52)
Here's how to calculate the hourly difference:
1. Convert annual median incomes to hourly incomes:
[tex]\text{Hourly income for males} = \frac{M}{H \times W} \\\\\text{Hourly income for females} = \frac{F}{H \times W}[/tex]
2. Calculate the difference in hourly incomes:
[tex]\text{Hourly difference} = \text{Hourly income for males} - \text{Hourly income for females}[/tex]
Let's plug in hypothetical numbers for illustration:
- Median income for males: M = 100,000 dollars per year
- Median income for females: F = 80,000 dollars per year
- Average hours worked per week: H = 40 hours
- Number of weeks worked per year: W = 52
Calculate the hourly incomes:
[tex]\text{Hourly income for males} = \frac{100,000}{40 \times 52} = \frac{100,000}{2080} \approx 48.08 \text{ dollars/hour} \\\\\text{Hourly income for females} = \frac{80,000}{40 \times 52} = \frac{80,000}{2080} \approx 38.46 \text{ dollars/hour}[/tex]
Calculate the hourly difference:
[tex]\text{Hourly difference} = 48.08 - 38.46 = 9.62 \text{ dollars/hour}[/tex]
So, the hourly difference in median income between males and females with an advanced degree is approximately $9.62/hr. To provide an exact answer, please supply the specific median income values for males and females with an advanced degree.
The complete question is:

Mary is creating valentine’s Day card for her friends and can choose from white,red,or pink construction paper to create a heart.On the heart she can use a black blue or green marker to write out her message and she can’t finish the valentine by sprinkling gold or silver glitter.Wh is the probability that her valentine to her friend will be on either red or pink construction paper with. black market and gold glitter?
Answer:
(1/9)
Step-by-step explanation:
Mary can choose from white,red,or pink construction paper to create a heart.
And she can use black, blue or green marker to write out her message and she can’t finish the valentine by sprinkling gold or silver glitter.
The probability that her valentine to her friend will be on either red or pink construction paper with black marker and gold glitter.
The probability that she uses red or pink construction paper = (2/3)
(since red or pink are two out of the total 3 sample spaces available for construction paper)
Probability that she uses black marker = (1/3)
(Black is one of the 3 sample spaces for markers)
Probability that she uses gold glitter = (1/2)
(Gold glitter is one of two sample spaces for glitters)
The required probability is then
(2/3) × (1/3) × (1/2) = (1/9)

If sally got 28 questions correct and received 70% on the exam, how many questions were on the exam
Answer: 40
Step-by-step explanation:
Number of correct questions Sally got = 28 questions
Percentage of correct questions answered= 70% on the exam,
Total number of questions in the exam = Unknown
Let the total questions in the exam be represented as y.
Since Sally got 70% correctly, this will be:
70% of y = 28
70/100 × y = 28
0.7 × y = 28
0.7y = 28
Divide both side by 0.7
0.7y/0.7 = 28/0.7
y = 40
There are 40 questions in the exam.
Simplify (-2x^4y^2)^3
Final answer:
The expression (-2x⁴y²)³ simplifies to -8x¹²y⁶, by individually raising the coefficient and each variable to the third power.
Explanation:
To simplify the expression (-2x⁴y²)³, you must raise both the numerical coefficient and the variables to the third power. Remember that raising a power to a power multiplies exponents and raising a negative number to an odd power results in a negative number.
First, raise -2 to the third power: (-2)³ = -8Then raise x⁴ to the third power: (x⁴)³ = x¹²Lastly, raise y² to the third power: (y²)³ = y⁶Putting it all together, the expression simplifies to -8x¹²y⁶.

Given:
The rectangular prism has a length of 25 feet, a width of 10 feet and a height 55 feet.
The triangular prism has a base length of 25 feet, a height of 8 feet, and a prism height of 55 feet.
To find:
The total area to be painted.
Solution:
There are 4 external surfaces for the rectangular prism and 4 external surfaces for the triangular prism.
The rectangular prism has 4 rectangles out which there are 2 sets of similar rectangles.
There are two rectangles with lengths of 25 feet and widths of 10 feet while the other two rectangles have lengths of 55 feet and widths of 10 feet.
The area of a rectangle with a length of 25 feet and a width of 10 feet [tex]= 25(10)= 250[/tex] square ft.
The area of two such rectangles [tex]= 2(250) = 500[/tex] square feet.
The area of a rectangle with a length of 55 feet and a width of 10 feet [tex]= 55(10)= 550[/tex] square feet.
The area of two such rectangles [tex]= 2(550) = 1100[/tex] square feet.
The triangular prism has 2 triangles and 2 rectangles.
The triangles have base lengths of 25 feet and heights of 8 feet while the rectangles have lengths of 55 feet and heights of 14.8 feet.
The area of a triangle with a base length of 25 feet and a height of 8 feet [tex]= \frac{1}{2}(25)(8)= 100[/tex] square feet.
The area of two such triangles [tex]=2(100)= 200[/tex] square feet.
The area of a rectangle with a length of 55 feet and a width of 14.8 feet [tex]= 55(14.8)= 814[/tex] square feet.
The area of two such rectangles [tex]= 2(814) = 1628[/tex] square feet.
The total area to be painted [tex]=500+1100+200+1628 = 3128[/tex] square feet.
So an area of 3128 square feet is to be painted.
An area of 3128 square feet is to be painted.
The rectangular prism has a length of 25 feet, a width of 10 feet and a height 55 feet.

If a normal distribution has a mean of 44 and a standard deviation of 8, what
is the z-score for a value of 46?
O A. 1.25
O B. 1.75
O c. 0.75
O
D. 0.25
Answer:
The answer to this question is gotta be 0
Step-by-step explanation:
Because a normal distribution gives an area between 0 and z and the area for P(X=46) = 0
The correct answer is option D: 0.25. The z-score for a value of 46 is 0.25.
To calculate the z-score for a given value in a normal distribution, we use the formula:
z = [tex]\frac{{x - \mu}}{{\sigma}}[/tex]
where:
x - the value
[tex]\mu[/tex] - the mean
[tex]\sigma[/tex] - the standard deviation
Given:
x - 46
[tex]\mu[/tex] - 44
[tex]\sigma[/tex] - 8
We can plug these values into the formula:
z = [tex]\frac{{46 - 44}}{{8}}[/tex]
z = [tex]\frac{{2}}{{8}}[/tex]
z = 0.25
So, the z-score for a value of 46 is 0.25.
The question is:
If a normal distribution has a mean of 44 and a standard deviation of 8, what is the z-score for a value of 46?
