The employees that the company had a year ago is 500.
How many employees were there last year?Percentage is the rate expressed as a number out of 100. Percentage is used to measure the frequency of a dataset. The sign that represents percentages is %.
The employees last year would be greater than the employees this year. The equation that can be used to represent employees last year is:
Employees this year = employees last year x (1 - percentage decrease)
335 = employees last year x (1 - 0.33)
335 = employees last year x 0.67
employees last year = 335 / 0.67
employees last year = 500

A. (5, -5)
B. (5, 0)
C. (2, -2)
D. (2, -1)
Answer:
B
Explanation:
x = 5
2x + y = 10
Substitute x = 5 into 2x + y = 10
2(5) + y = 10
10 + y = 10
y = 0

How should the facts be explained?
According to the information provided, Helena was interested to know whether the quadrilaterals were congruent.
The quadrilaterals in this instance cannot be mapped into one another via a series of stiff transformations, hence they are not congruent.

The government levies a consumption tax known as a sales tax on the purchase of goods and services.At the point of sale, a standard sales tax is imposed, collected by the shop, and paid to the government.
Calculate sales tax ?
The formula sales tax = purchase price x sales tax rate can be used to calculate the sales tax that was imposed to a purchase by simply multiplying the tax rate by the purchase price.The final price paid with tax is calculated by adding the sales tax to the initial purchase price. The Short Answer: Retail purchases are subject to sales tax.It is used to fund local and state budgetary expenses including fire departments, roads, and schools.The Detailed Response: Sales tax is a type of consumption tax that is typically levied on goods purchased by customers from shops. Only when the taxable supply is made during a "taxable activity" is it assessed and paid.The amount to be taxed is the value of the products or supply.The nature of the sales tax requires that the customer bear the majority of the tax burden.Sales tax is an indirect tax, which explains why.

friends. Determine the number of regular and early morning hours that Aisha could work.
Answer:
Minimum 7 early morning hours
Maximum 13 regular hours
Step-by-step explanation:
x: number of regular hours
y: number of early morning hours
i) x + y = 20
ii) 7x + 8.5y = 150
ii - 7i
1.5y = 10 --> y = 10/1.5 = 20/3 = 6 2/3
x + 20/3 = 20 --> x = 40/3 = 13 1/3
She could work a minimum of 7 hours in the early morning and a maximum of 13 regular hours.
results from previous studies showed 79% of all high school seniors from a certain city plan to attend college after graduation. a random sample of 200 high school seniors from this city reveals that 162 plan to attend college. does this indicate that the percentage has increased from that of previous studies? test at the 5% level of significance. what is the p-value associated with your test of hypothesis?
The allegation that the proportion has increased from that of earlier studies is not supported by enough data.
What is Hypothesis test?Hypothesis test: A statistical hypothesis test is a method of statistical inference used to decide whether the data at hand sufficiently support a particular hypothesis. Hypothesis testing allows us to make probabilistic statements about population parameters
Let p represent the population percentage.
Then, Null hypothesis : H₀:p=0.79
Alternative hypothesis : H₀:p>0.79
The hypothesis test is a right-tailed test because the alternative hypothesis is right-tailed.
Out of 200 high school seniors in this city, 162 intend to enroll in college, according to a random sampling.
Because n = 200 > 30 we must employ the z-test (otherwise we use t-test.)
p`=162/200=0.81
Population percentage test statistic:
[tex]z=(p`-p)/[/tex][tex]\sqrt{p`(1-p)/n[/tex]
[tex]z=(0.81-0.79)/\sqrt{0.81(1-0.81)/200}[/tex] =0.720984093915≈0.72
Consequently, the sample test statistic's z-value is 0.72.
Right-tailed test P-value:
[tex]p(z > 0.72)=1-p(\leq 0.72)[/tex]
≈[tex]1-0.7642375[/tex]
≈[tex]0.2357625[/tex]
≈[tex]0.2358[/tex]
We are unable to reject the null hypothesis since the p-value is higher than the threshold for significance (0.05).
Therefore, we draw the conclusion that the allegation that the proportion has increased from that of earlier studies is not supported by enough data.

I don't know how to find the vertex for this
The equation of the function in standard form is 3x + y = 25.
What is a quadratic function?
f(x) = ax2 + bx + c, where a, b, and c are numbers and an is not equal to zero, is a quadratic function. A parabola is the shape of a quadratic function's graph. Although the "width" or "steepness" of a parabola can vary as well as its direction of opening, they all share the same fundamental "U" form.
From the given table we can get the dy/dx which is the slope (m) ,
Therefore,
dy/dx = (7 - 10 ) / ( 4 - 3 )
dy/dx = -3
Now,
( y - y1 ) = m ( x - x1 )
Putting the value from the table,
( y - 10 ) = -3 ( x -5 )
=> y - 10 = -3x + 15
=> 3x + y = 25

n = 15 + c.
Which algebraic expression models the situation?The initial number of cookies that she has is given by:
30.
(as stated in the problem).
She gives half of that amount to her students, hence the number of cookies that she has remaining is:
0.5 x 30 = 15 cookies remaining.
(to find the half of an amount, we can either divide by 2 or multiply by 0.5).
Then, on her way home, she purchases c cookies, hence the total number of cookies that she has when she reaches home is given by the following expression:
15 + c.
(she had 15, and then c was added to that amount).

Here, for instance, we can plot a graph showing the type and quantity of school supplies used by pupils in a class based on the data provided below.
Rectangle: Rectangles have parallel opposite sides; therefore, D must be positioned such that CD is parallel to AB and AD is parallel to BC. This necessitates that point D be.

Trapezoid: A trapezoid has one set of parallel opposed sides. As a result, we must select point E such that either AE or CD are parallel to AB.
We have picked point E in the accompanying picture so that AE and BC are parallel.
