leonid [27]1 year ago

Step-by-step explanation:

we need to look up the p-value in the z-table.

for z = 1.36 we get 0.91309.

this is p(the population mean is less than 9).

left-tailed test (less) : p-value = z-table(1.36)

right-tailed test (larger) : p-value = 1 - z-table(1.36)

two-tailed test (not equal to) :

p-value = 2×minimum(z-table(1.36), 1 - z-table(1.36))

(a) is clearly the left-tailed test.

p-value (as above) = 0.91309

(b) is clearly the two-tailed test.

z-table(1.36) = 0.91309

1 - z-table(1.36) = 1 - 0.91309 = 0.08691

the minimum of these 2 values is 0.08691.

so,

p- value = 2×0.08691 = 0.17382

FYI - in both cases that p- value is not small enough (typically it should be <= 0.05) to drop H0.

F(x) = x<br> Horizontal stretch by a factor of 2<br> Shift left 3 units<br> . Shift up 5 units
WARRIOR [948]

Answer:

f(x) = 0.5(x + 3)^2 + 5.

Step-by-step explanation:

The horizontal stretch is given by multiplying by 1/2 or 0.5:

f(x) = 0.5x^2

Now a shift of 3 to the left  gives f(x) = 0.5(x + 3)^2.

5 units up gives 0.5(x + 3)^2 + 5.

In the figure, a square is inside another bigger square.
evablogger [386]

Answer:

Part 1) The length of the diagonal of the outside square is 9.9 units

Part 2) The length of the diagonal of the inside square is 7.1 units

Step-by-step explanation:

step 1

Find the length of the outside square

Let

x -----> the length of the outside square

c ----> the length of the inside square

we know that

x=a+b=4+3=7\ units

step 2

Find the length of the inside square

Applying the Pythagoras Theorem

c^{2}= a^{2}+b^{2}

substitute

c^{2}= 4^{2}+3^{2}

c^{2}=25

c=5\ units

step 3

Find the length of the diagonal of the outside square

To find the diagonal Apply the Pythagoras Theorem

Let

D -----> the length of the diagonal of the outside square

D^{2}= x^{2}+x^{2}

D^{2}= 7^{2}+7^{2}

D^{2}=98

D=9.9\ units

step 4

Find the length of the diagonal of the inside square

To find the diagonal Apply the Pythagoras Theorem

Let

d -----> the length of the diagonal of the inside square

d^{2}= c^{2}+c^{2}

d^{2}= 5^{2}+5^{2}

d^{2}=50

d=7.1\ units

ILL MARK BRAINIEST IF YOU DO THIS RIGHT!!!
Arlecino [84]
First let’s find the equation:
a = (42-21)/(26-13)
a= 21/13
y-y1 = a(x-x1)
y-21=(21/13)(x-13)
y-21=(21/13)x - 21
y=(21/13)x-21+21
y=(21/13)x

Now we will find the other point:
X = 2 >> y =(21/13)*2 = 3.23 (not)
X = 3 >> y =(21/13)*3 = 4.84 (not)
X = 4 >> y =(21/13)*4 = 6.46 (not)

X = 5 >> y =(21/13)*5 = 8.07 (yes) find the answer

A number decreased by the sum of the number and four<br> and please show the steps
FromTheMoon [43]

let the number be x.

a number decreased means

x-

and the sum of the number and 4 is

x+4

to put the expression together, we get. put them in parentheses

x - ( x+4 )

= x - x -4

= - 4

Robert weighs 20 pounds more than his friend Genesis. The sum of their weights is more than 220 lbs. What is are the smallest po
Vesnalui [34]

Answer:robert=120lbs,genesis=100

Step-by-step explanation:take genesis as (x) and since robert is 20 pounds heavier he would be (X+20) so:

x+(x+20)  =220lbs

2x+20=220

2x=220-20

2x=200

x=100 which we took as genesis

which leaves robert's weight 100 +20 =120
