Answers

Answer 1
W = 5

-4w - 4 = -24
+4 +4
-4w = -20
-4w/-4 = -20/-4
w = 5
Answer 2

Answer:

The answer is w = 5.

Step-by-step explanation:

1) Divide both sides by -4.

[tex]w + 1 = \frac{ - 24}{ - 4} [/tex]

2) Two negative numbers makes a positive.

[tex]w + 1 = \frac{24}{4} [/tex]

3) Simplify 24/4 to 6.

[tex]w + 1 = 6[/tex]

4) Subtract 1 from both sides.

[tex]w = 6 - 1[/tex]

5) Simplify 6 - 1 to 5.

[tex]w = 5[/tex]

Therefor, the answer is w = 5.

State whether each set of hypothesis is valid for a statistical test and briefly explain why ?

Answers

Complete Question:

State whether each set of hypothesis is valid for a statistical test and briefly explain why ?

[tex]H_0 : \mu=10; \ \ \ H_a : \mu\ne10[/tex]

[tex]H_0 : p \ne 0.5; \ \ \ H_a : p = 0.5[/tex]

[tex]H_0 : p_1 < p_2; \ \ \ H_a : p_1 \supset p_2[/tex]

Answer:

[tex]H_0 : \mu=10; \ \ \ H_a : \mu\ne10[/tex] --- Valid

[tex]H_0 : p \ne 0.5; \ \ \ H_a : p = 0.5[/tex] --- Invalid

[tex]H_0 : p_1 < p_2; \ \ \ H_a : p_1 \supset p_2[/tex] --- Invalid

Step-by-step explanation:

For a test of hypothesis to be valid, the null hypothesis has to contain some form of equality i.e. [tex]=, \le,\ or\ \ge[/tex]

So, the above will be used to test for validity in the given tests of hypotheses.

[tex]H_0 : \mu=10; \ \ \ H_a : \mu\ne10[/tex]

This is valid because the null hypothesis has an equality sign.

The null hypothesis is: [tex]H_0:\mu = 10[/tex]

[tex]H_0 : p \ne 0.5; \ \ \ H_a : p = 0.5[/tex]

This is invalid because the null hypothesis does not have any equality sign. The null hypothesis is: [tex]H_0:p \ne 0.5[/tex]

[tex]H_0 : p_1 < p_2; \ \ \ H_a : p_1 \supset p_2[/tex]

This is invalid because the null hypothesis does not have any equality sign. The null hypothesis is: [tex]H_0:p_1 <p_2[/tex]

A. -1
B. 1
C. -2
D. 2
E. -5
F 5

Answers

Answer:

-2

Step-by-step explanation:

For the given expression to be undefined, this means that the denominator must be zero.

From the given expression, the denominator is x + 2

Equating this to zero;

x+2 = 0

Subtract 2 from both sides

x+2-2 = 0 -2

x = -2

Hence the value of x that makes it undefined is -2

Olivia buys cookies and apples at the store.
• She pays a total of $24.79.
• She pays a total of $4.75 for the cookies.
• She buys 4 bags of apples that each cost the same amount.

Answers

Each bag cost $5.01. Why?

Because $24.79-4.75= $20.04
You said she bought 4 bags of apples each costing the same so now you divide $20.04 by 4 giving you $5.01

x°=180-116

x°=64°

Answer:

  x = 3

Step-by-step explanation:

The equation can be rewritten to make use of the graphing calculator's ability to identify function zeros:

  x(x -2)(x +3) -18 = 0

The attached shows x = 3 is the only real solution.

We're not sure what "system of equations" is intended. Perhaps it is ...

  y = 18

  y = x(x -2)(x +3)

To create the expression we graphed, we effectively subtracted the first equation from the second.

A tree is broken at a height of 7m from the ground and its top touches the ground at distance of 24m from the base of the tree. Find the original height of the tree. pls help with steps

Answers

let the broken part of tree be x
then total height of tree=7+x
since it form a right angled triangle with base 24m and height 7m and hypotenuse be x
then by using Pythagoras theorem
(hypotenuse)^2=(base)^2+(height)^2
x^2=24^2+7^2
x^2=576+49
x^2=625
x=25
therefore height of tree =x+7=25+7=31

The expression that represents all clothing is being marked down 15%.

is A) 0.85x.

What is the percentage?

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

We know fractions and percentages are related.

Assuming the cost of clothing to be 'x'.

∴ After the markdown of 15% it is,

= {(100 - 15)/100}×x.

= {85/100}×x.

= 0.85x
