Which of the following groups of numbers is in order from least to greatest?

0.54, 7/10, 40%
3/4, 0.8, 94%
67%,1/2 , 0.8
7/10, 0.54, 67%

Answer:

a=-39; s=0.75

Step-by-step explanation:

Solve the System of Equations by Substitution.

First, solve one of the equations for a variable. I'll do the 2nd one because it only has one variable.

a+24=-15 -------> a=-39

Now we know what a is just plug it back into the other equation and get s.

[tex]\frac{a-3}{7s} =-8[/tex]

[tex]\frac{-39-3}{7s} =-8[/tex]

[tex]\frac{-42}{7s} =-8[/tex]

Switch the -8 and 7s

[tex]\frac{-42}{-8} =7s[/tex]

Simplify the fraction

5.25=7s

Divide by 7 to isolate the s

0.75=s

Answer:

2)a+24=-15

a=-15-24

a=-39

Answer:

The probability that the next person will purchase no more than one costume [tex]\frac{219}{239}[/tex].

Step-by-step explanation:

The data for a single day is s follows:

The total number of customers is, N = 236 + 202 + 40 = 478.

Let X denote the number of costumes purchased by the next person.

Compute the probability that the next person will purchase no more than one costume as follows:

[tex]P (X\leq 1)=1-P(X>1)[/tex]

               [tex]=1-\frac{40}{478}\\\\=\frac{478-40}{478}\\\\=\frac{438}{478}\\\\=\frac{219}{239}[/tex]

Thus, the probability that the next person will purchase no more than one costume [tex]\frac{219}{239}[/tex].

Step-by-step explanation:

try that, if it's the wrong answer then lmk!

Step-by-step explanation:

Let

base=x

height=x+5

we know that in a parrelogram

[tex]\boxed{\sf Area=base×height}[/tex]

[tex]{:}\rightarrowtail\sf x(x+5)=204 [/tex]

[tex]{:}\rightarrowtail\sf x^2+5=204 [/tex]

[tex]{:}\rightarrowtail\sf x^2=204-5 [/tex]

[tex]{:}\rightarrowtail\sf x^2=199 [/tex]

[tex]{:}\rightarrowtail\sf x=\sqrt {199}[/tex]

[tex]{:}\rightarrowtail\sf x=14.1[/tex]

[tex]{:}\rightarrowtail\sf base=14.

[tex]{:}\rightarrowtail\sf Height =14.1+5=19.1feet [/tex]

Answer:

No, not a function

Step-by-step explanation:

Functions cannot have two or more same domain and different range. (3,3) and (3,9) have same domain and different range.

Answer:

the product of 5 and a number

Step-by-step explanation:

product is the result of a multiplication problem

5c is the same as 5 times c

we don’t write an x (5xc) because x is sometimes used as a “placeholder” instead of c

Answer:

Yes I can help you :)

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

Multiplying fractions does not require that the fractions have the same denominator. Instead, the numerators are multiplied with each other and the denominators are multiplied with each other. However, the resulting fraction may not be in lowest terms so it may need to be reduced.

Answer: They are diffrent

Step-by-step explanation: The logistic equation was first published by Pierre Verhulst in 1845. This differential equation can be coupled with the initial condition P(0) = P0 to form an initial-value problem for P(t). Suppose that the initial population is small relative to the carrying capacity. Then P K is small, possibly close to zero.

The logistic regression coefficients are the coefficients b 0, b 1, b 2,... b k of the regression equation: An independent variable with a regression coefficient not significantly different from 0 (P>0.05) can be removed from the regression model (press function key F7 to repeat the logistic regression procedure).

By the way, this is copied from the internet.

Multiply the numbers:

-2 x 3 x -7 = 42

The the letters x time x = x^2

Y x y = y^2

Now combine for final answer:

Answer:

no

Step-by-step explanation:

9.080 is greater

Answer:

x + y = 2

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Given

y + 3 = - (x - 5) ← distribute

y + 3 = - x + 5 ( subtract 3 from both sides )

y = - x + 2 ( add x to both sides )

x + y = 2 ← in standard form

Answer:

64

Step-by-step explanation:

Complementary angles have to add up to 90.

90-26=64.

Answer:

  64°

Step-by-step explanation:

  Complementary angle means it add up to 90°

  26° + x = 90°

           x = 64°

Answer:

In order to use the Pythogrean theorem you must first use the points to form a triangle then count the side length in order to get your numbers. It should be 7^2+2^2=c^2 and your answer should be 7.28. This person subtracted the x coordinates from the x coordinate and the y from the y to get their numbers.

Answer:

i dunno about other people but the formula I learned needs the question to give you the radius.  

Step-by-step explanation:

ACP=(mAB/360)(2 pi r)

=(74/360)(6.28 r)

=1.29r

Answer:ACP=(mAB/360)(2 pi r)

=(74/360)(6.28 r)

=1.29r

Answer:

medium

Step-by-step explanation:

yea sure so according to my calculations small is 3.95 so if we subtract the medium size minus 3.95 which would be 4.25-3.95 the difference is 30 cents now if we subtract large size by small size 4.55-3.95 the difference is .60 cents therefore if she wants to save .60 cents i would choose medium size but large minus medium 4.55-4.25 it would also be .30 cents
