Answer 1

Answer:

Step-by-step explanation:

Your first step is to figure out which variable you want to cancel out.

Luckily, all these problems have x or y already set up to eliminate.

You can find these variables because they are opposite signs of each other, such as -x and x

Add the y's together and the #'s on the other side together, then solve to find the 2nd variable. Once you find one, you can plug that answer into the easier of the two equations and solve for the other variable.

A standard number cube is rolled. What is the probability of rolling a number less than or equal to 2?

Answers

Answer: The probability is 1/3

Explanation: I am guessing by "standard number cube" it means the classic six-sided dice. This dice has numbers 1 through 6 on each side. There are only 2 numbers less than or equal to two. 1 and 2. This means that 2/6 rolls will roll a 1 or 2. You can simplify by dividing the fraction by 2. This gives you 1/3.

Magician Anthony has in his magic hat 14 grey, 8 white and 6 black mice. What is
the least number of mice he has to take out of his hat blindfolded to be absolutely
certain that he has got at least one mouse of each colour?

Answers

The least number of mice that he has to take out of his hat would be 23.

How to solve for the least number of mice

We have the following details to solve this problem

x = 14

t = 8

u = 6

n1 = x + t + 1

= 14 + 8 + 1 = 23

n2 = t + u + 1

= 8 + 6 + 1 = 15

n3 = x + u + 1

= =14+6+1=21

From here the

max n (n1, n2, n3) = 23, 15, 21

Hence the least number that has to be taken out would be 23.

What is the length of the longer side of the rectangle?

Answers

Answer:

5.21 i took the test

Length of longer side of the rectangle in which a quarter circle is drawn onto the shorter side is 5.12 cm

What is area of a geometric shape?

The area of a two dimensional shape is the space enclosed by the boundary of the shape. The area of a rectangle is the product of its length and breadth, the area of a circle is π×(radius)².

Given that, the shorter side of a rectangle is 4cm.

Let the length of the longer side of the rectangle is x.

Then, the area of rectangle is 4x

Also, the sum of area of rectangle and a quarter circle is 33.4cm²

And the radius of quarter circle = shorter side of rectangle

Therefore, area of quarter circle = (1/4)×π(4)²

According to question,

    4x + (1/4)π(4)² = 33.4

     4x + 4π = 33.4

     4x = 33.4 - 4×3.14

     4x=20.84

       x=5.21

Hence, the longer side of rectangle is 5.21 cm when the shorter side is 4cm and a quarter circle is drawn onto the shorter side of the rectangle.

Agency leadership is very interested in trend analysis. Using the 750 randomly selected vehicles as their​ sample, data was collected to determine which vehicles currently meet or exceed fuel economy standards and which vehicles currently do not meet fuel economy standards. This information is found in the Meet or Not Meet Current Standards column. Agency leadership asks your team to construct a​ 95% One-Sample proportion confidence interval for the population proportion of all vehicles that meet current fuel economy standards. Assume that all necessary Central Limit Theorem conditions for a​ One-Proportion confidence interval have been met. What is the​ 95% lower​ limit?

Answers

Using the z-distribution, as we are working with a proportion, considering that the estimate is of 90%, the 95% lower​ limit is of 0.8785.

What is a confidence interval of proportions?

A confidence interval of proportions is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.

In this problem, we have that:

There is a 95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so [tex]z = 1.96[/tex]. We suppose an estimate of [tex]\pi = 0.9[/tex].The sample size is of n = 750.

Hence, the lower bound of the interval will be given by:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.9 - 1.96\sqrt{\frac{0.9(0.1)}{750}} = 0.8785[/tex]

Answer:

[tex]\frac{1}{3}, \frac{2}{5} , \frac{3}{4} , \frac{4}{5}[/tex]

Step-by-step explanation:

Start by making a common denominator. That way we can just compare the numerators of the fractions and easily order then from least to greatest. Start by finding the LCM(least-common-multiple) of the denominators.

The LCM of 3, 4, and 5, is 60.

So let's make each of the fractions have a denominator of 60.

Start with [tex]\frac{2}{5}[/tex],

[tex]\frac{2}{5} =\frac{x}{60}[/tex], no we have to solve for x, and since we multiply by 12 to get to 60 from 5, we multiply 2 by 12 as well.

So, [tex]x=24[/tex].

Now do the same for each fraction.

[tex]\frac{1}{3} =\frac{x}{60}[/tex], we multiply by 20, so [tex]x=20[/tex]

[tex]\frac{4}{5} =\frac{x}{60}[/tex], we multiply by 12, so [tex]x=48[/tex]

[tex]\frac{3}{4}=\frac{x}{60}[/tex], we multiply by 15, so [tex]x=45[/tex]

So now are new fractions are [tex]\frac{24}{60} , \frac{20}{60} ,\frac{48}{60} , \frac{45}{60}[/tex]

Now just order these like normal since they have a common denominator.

[tex]\frac{20}{60} ,\frac{24}{60} , \frac{45}{60} , \frac{48}{60}[/tex]

Now revert them and make them there original values

[tex]\frac{1}{3}, \frac{2}{5} , \frac{3}{4} , \frac{4}{5}[/tex]

The given equation is [tex]3^2^x = 9^3^x^-^4[/tex]

We need to find the value of x.

We can write the given equation as below to make the bases same.

as 9 is equal to 3²

[tex]3^2^x = 3^2^(^3^x^-^4^)[/tex]

Apply distributive property in exponential part.

[tex]3^2^x = 3^(^6^x^-^8^)[/tex]

Now compare the exponential part as the bases are same

2x=6x-8

8=6x-2x

8=4x

Divide both sides by 4

x=2
