$\dfrac{10}{9}=\dfrac{9+1}{9}=\dfrac{9}{9}+\dfrac{1}{9}=1\dfrac{1}{9} \ \textgreater \ 1\\\\therefore\\\\\dfrac{10}{9}\ is\ closter\ to\ 1$

10/9 would be closer to 1 because 9/9 would be 1 whole and 10/9 is a little bigger than a whole
So it would be closer to 1

Hope this helped!! :D

True or False: A race car driver tested his car for time from 0 to 60 mph, and in 20 tests obtained an average of 4.85 seconds w

vredina [299]

Answer:

False

Step-by-step explanation:

given that a race car driver tested his car for time from 0 to 60 mph, and in 20 tests obtained an average of 4.85 seconds with a standard deviation of 1.47 seconds.

Sample size n = 20

since population standard deviation is not known, we can use t critical value for finding out the confidence interval

df=19

t critical = 2.045

Margin of error = $2.045*\frac{s}{\sqrt{n} } \\=2.045*\frac{1.47}{\sqrt{20} } \\=0.6722$

conidence interval = Mean±Margin of error

= $(4.85-0.6722, 4.85+0.6722)\\= (4.1778, 5.5222)$

The given confidence interval is (4.52, 5.18)

Hence the statement is false.

AWARDING EXTRA POINTSWhat is the distance between point A (-3, -2) and Point B (4, -7)?

kenny6666 [7]

Answer:

Hi there!

Your answer is:

8.6 units

Step-by-step explanation:

The distance formula is

√ ( (x2-x1)^2 + (y2-y1)^2 )

In your points:

A (-3, -2)

-3 is x1

-2 is y1

B (4, -7)

4 is x2

-7 is y2

Plug in to distance formula

√ ( 4-( -3))^2 + ( -7 - (-2))^2

√ (4+3)^2 + (-7+2)^2

√ (7^2) + ( -5)^2

√ 49 + 25

√ 74

This equals roughly 8.6 units!

What is the slope of y = - x + 7

svet-max [94.6K]

$\green{\huge{\red{\boxed{\green{\mathfrak{QUESTION}}}}}}$

What is the slope of y = - x + 7

$\red{ \bold{ \textit{STANDARD \: EQUATION}}}$

$y = mx + c$

$WHERE \\ m = SLOPE \\ c = Y - INTERCEPT$

$\huge\green{\boxed{\huge\mathbb{\red A \pink{N}\purple{S} \blue{W} \orange{ER}}}}$

$\blue{A.T.Q}$

$y = mx + c \sim y = ( - 1)x + 7$

$\orange{SO}$

m= (-1)

which is equal to the slope of the equation .
