After the z value is calculated, the ____________ is obtained from a table of z-scores.

7 0

<span>The critical value will be established. This is the point at which the researcher can reject the null hypothesis because the value falls outside the bounds at which the result was due to random chance. Values inside this bound show that the result cannot be determined to be due to the variables, so they cannot be used to reject the null hypothesis.</span>

Donna borrowed $10,500 at a simple interest rate of 4% for 3 years to buy her new car. How much interest would Donna pay and how much is the car altogether ?

<h3>Given:-</h3>

$\bullet$ Principal (P) = $10,500

$\bullet$ Rate of interest (r) = 4%

$\bullet$ Time (t) = 3 years

Interest of Donna and amount of car altogether.

<h2>Solution:-</h2>

We know,

${ \boxed{\rm \red {I \: = \frac{Prt}{100}}}}$

$\therefore$ I = $\frac{10,500 \: × \: 4 \: × \: 3}{100}$

I = $\frac{126,000}{100}$

I = $1260

Now,

Amount of the car = $ (10,500 + 1260)

= $ 11,760

<h3><u>$</u><u>1</u><u>2</u><u>6</u><u>0</u> interest would Donna pay and <u>$</u><u>1</u><u>1</u><u>,</u><u>7</u><u>6</u><u>0</u> is the car altogether. [Answer]</h3>

Which is the result when the equation y = -2/5x + 5/2 is converted to<br> standard form?

mixer [17]

Answer:

$4x+10y-25=0$

Step-by-step explanation:

$y=-\frac{2}{5} x+\frac{5}{2}$

Multiply by 10 on both sides,

$10y=-4x+25\\$

so $4x+10y-25=0$

What is the slope-intercept form of the function described by this table?

Pavel [41]

Answer:

y = -4x +2

Step-by-step explanation:

As x-values increase by 1, y-values decrease by 4. The slope of the line is ...

... m = (change in y)/(change in x) = -4/1 = -4

We can use the first (x, y) pair as a point to use in the point-slope form of the equation of a line. That form can be written, for slope m and point (h, k) ...

... y = m(x -h) +k

using m = -4 and (h, k) = (1, -2), we can fill in the numbers to get ...

... y = -4(x -1) -2

... y = -4x +4 -2 . . . . eliminate parentheses

... y = -4x +2 . . . . . . slope-intercept form

_____

<em>Alternate approach</em>

After you recognize that a change in x of 1 gives a change in y of -4, you can work backward one step to find the table value for y corresponding to x=0. That will be -2+4 = +2. Now, you know both the slope (-4) and the y-intercept (+2), so you can write the equation directly from this knowledge:

... y = -4x +2

At the market,8 apples cost $4.How much do 9 apples cost?

svet-max [94.6K]

Divide the price by amount to find out how much each costs. multiply that by 9. 4 (divided by) 8 = .5, or 50cents. each apple is 50cents. multiply .50 by 9. It costs 4.50. Hope this helps

I need help with this question

nata0808 [166]

I don't know if you've learnt this, but there's something called the KFC rule (you use it when dividing fractions), so k basically stands for keep (so you keep the first fraction), f stands for flip (so you flip the second fraction) and c stand for change (you change the division sign to a multiplication sign)

So you get

5/20*11/5

55/100

which is 11/20

so, an answer of 11/20 would make Quintin correct
