A dressmaker has 75 yards of lace. it takes
[tex]1 \frac{1}{2} [/tex]
yards of lace to decorate one pocket.
How many pockets can she decorate with the lace she has.​

Answers

Answer:

50 pockets

Step-by-step explanation:

Total yards of lace = 75

Yards to decorate one Pocket = 1 1/2 yards

How many pockets can she decorate with the lace

Number of pockets she can decorate with the lace = Total yards of lace / Yards to decorate one Pocket

= 75 ÷ 1 1/2

= 75 ÷ 3/2

= 75 × 2/3

= 150/3

= 50

Number of pockets she can decorate with the lace = 50 pockets

can someone solve a - 3 over 7 s = -8


and a + 24 = -15

STEP BY STEP PLEASE.

Answers

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

I think you would multiply 223 with 15 then divide that number with 792. That’s what I’m guessing

40 POINTS- Are a logistic equation and a logistic regression model the same thing? If not, what's the difference?
I have a logistic equation and need to make a logistic regression model from it but I'm not sure how to. Any help is appreciated :)

Answers

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).

Several bags of marbles of equal number are added to an empty jar. The total number of marbles in the jar is 1,320. A student places 9 more bags of marbles in the jar, bringing the total number of marbles in the jar to 1,518 marbles. If each bag in the jar contains the same number of marbles, how many marbles does each bag contain?

Answers

Answer: 22 Marbles

Step-by-step explanation:

1,518 - 1,320 = 198

198 ÷ 9 = 22

Answer:

Work out 5.9 + 3.172

Answers

Answer:

9.072

Step-by-step explanation:

Answer:

9.072

Step-by-step explanation:

For this problem, we will simply use the property of 0 and addition to accumulate a sum.

Note, any digit not shown to the right of a decimal can be written with a zero. So 5.9 can be rewritten as 5.900.

Let's perform the addition.

5.900

+ 3.172

-----------

9.072

Using the idea of zeros to the right of the decimal, we are able to trivially complete this sum.

Hence, the answer is 9.072.
