# A home has a room with length 22 feet and width 25 feet. Which dimensions could represent a scale model of the room? I’ll put you as brainliest A)Length =6.5in width=7.5inches B) length=13inch width=14inch C) length=17.6inch width=19.5inches D) length =11inches width=12.5inches

When making a scale model, you need to ensure that both values are in proportion, or work with the same constant.

In the case of Option D, the scale model is '2 feet : 1 inch'. Since multiplying 11 by 2 is 22 and 12.5 by 2 is 25, you know for sure that these numbers are in proportion

A quadratic function passes through the points ( − 5 , − 8 ) and ( 8 , − 8 ) . Find the equation for the line (axis) of symmetry.

The equation for the axis of symmetry is x=1.5.

Step-by-step explanation:

It is given that a quadratic function passes through the points ( − 5 , − 8 ) and ( 8 , − 8 ) .

In the given points y-coordinates are same, i.e., -8. It means both the points lie on the horizontal line y=-8.

If a quadratic function passes through two points (a,c) and (b,c), then the equation for the axis of symmetry is

According to the given points a=-5, b=8 and c=-8. Put these value in the above formula.

Therefore the equation for the axis of symmetry is x=1.5.

Can you show your work for me on divided Omg 0.6 and 12.9

0.6 divided by 12.9.

0.6 is outside the house for the divide then inside the house is 12.6
then you move your decimal point over 1 place so its 06 divide by 126.
after that 6 goes into 12 twice then your have a remainder of 09 then 6 goes into 9 once, our remainder is 3, then you put a 0 at the end of the decimal point of the 126. after that you bring down your zero and 6 goes into 30 five times.

Assume that the following confidence interval for the difference in the mean length of male​ (sample 1) and female babies​ (sample 2) at birth was constructed using independent simple random samples. What does the confidence interval suggest about the difference in length between male babies and female​ babies? minus −0.2 in. less than < mu 1 μ1 minus − mu 2 μ2 less than <1.7 in.a female babies are longer b male babies are longer
c there is no difference in the length between male and female babies

c. There is no difference in the length between male and female babies

Step-by-step explanation:

Hello!

If I understood correctly, the interval [-0.2;1.7] was constructed to estimate the difference between the population mean of the length of male babies at birth(μ₁) and the population mean of the length of female babies at birth (μ₂).

Estimated parameter: μ₁-μ₂

To make a desition using an interval your hypothesis must be two-tailed,

H₀: μ₁-μ₂ = 0

H₁: μ₁-μ₂ ≠ 0

The level of significance should be complementary to the confidence level of the interval. (For example, if the interval was constructed at 1 - α: 0.9, the test should have a level of α: 0.10)

Remember the Confidence interval is an estimation of the real value of μ₁-μ₂, so, under the null hypothesis you can say that:

If the interval contains the 0, then you don't reject the null hypothesis.

If the interval doesn't contain the 0, you reject the null hypothesis.

So since 0 is contained in the confidence interval, you support the null hypothesis, in other words, there is enough information to say that there is no difference between the average length of male and female babies at birth.

A human usually has 20 baby teeth, which are replaced by 32 adult teeth.Raul lost 8 of his baby teeth.Raul said he lost 4/10 of his baby teeth. Ana said Raul lost 2/5 of his baby teeth.Which of these conjectures are true?

Both of these conjectures are true.

What is conjecture?

A conclusion deduced by surmise or guesswork.

Given that, Raul lost 8 of his baby teeth. Raul said he lost 4/10 of his baby teeth. Ana said Raul lost 2/5 of his baby teeth. A human usually has 20 baby teeth,

According to Ana,

20x2/5 = 2x4 = 8

According to Raul,

20x4/10 = 2x4 = 8

In both the cases, the value is same.

Hence, both the explanation is correct.

coefficient

A coefficient is a number written with a variable to indicate the product of the number and the variable in a term.

What is a variable term?

In any of the algebraic expressions or an equation or a polynomial, a term contains at least one variable and a coefficient (numerical value). Thus, the coefficient of the term is one of the factors. So, the coefficient is indicated by the product of the number and the variable in a term.

Given statement:

The number written with a variable indicates the product of the number and the variable in a term is its coefficient. This is because it is a numerical value and it is the factor for the term.

E.g., 4xy - here 4 is the coefficient, and x y are the variables.

This can be written as 4 × x × y (product form).

What is 11(x+10)+5x=11+7x

X = -11.

11(x+10)+5x=11+7x

11x + 110 + 5x = 11 + 7x

(11x + 5x) + 110 = 7x + 11.

16x + 110 = 7x + 11.

16x + 110 - 7x = 7x + 11 - 7x

9x + 110 + 11.

9x + 110 - 110 =11 - 110.

9x/9 = -99/9

X = -11

How to get answer by Mimiwhatsup:

What is the degree of the polynomial below? 2x^2+3x+1

The degree of a polynomial is the largest exponent on the variable.

The only term in the given equation that has an exponent is 2x^2.

The exponent is 2, so the degree is 2

The degree of the polynomial for the quadratic equation (2x²+3x+1) is 2.

A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.

The quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

The given quadratic equation is (2x²+3x+1). From the definition, the degree of the polynomial is the highest power of the variable in a polynomial. In the above polynomial, the highest power is 2. Then the degree of the polynomial is 2.

Therefore, the degree of the polynomial is 2.
