Answer:

w≥15

Step-by-step explanation:

Subtract 80 from both sides to get -2w≤-30. Divide both sides by -2. Because it is negative, flip it. You will get w≥15.

<u>Sampe : Total</u>
25 : 750
(÷25) (÷25)
1 : 30
( x7) ( x7)
7 : 210

Answer: (a) There is a total of 210 orange cakes made on Monday.

The sample is 5 when corrected to the nearest whole number.
⇒Smallest possible number is 4.5

Total orange cakes baked on Tuesday = 4.5 x 30 = 135

P(Orange Cake) = 135/750 = 9/50

Answer: (b) The probability is 9/50

What is the center of the circle? Please show steps!

Vika [28.1K]

Answer:

<h2>A. (0, 4)</h2>

Step-by-step explanation:

The equation of a circle:

$(x-h)^2+(y-k)^2=r^2$

(h, k) - center

r - radius

We have the equation:

$x^2+(y-4)^2=25\\\\(x-0)^2+(y-4)^2=5^2$

h = 0, k = 4, r = 5

Suppose that a sample of size 100 is to be drawn from a population with standard deviation L0. a. What is the probability that t

NARA [144]

Answer:

The probability that the sample mean will lie within 2 values of μ is 0.9544.

Step-by-step explanation:

Here

the sample size is given as 100
the standard deviation is 10

The probability that the sample mean lies with 2 of the value of μ is given as

$P(| \bar{X}-\mu|$

Here converting the values in z form gives

$P(-2$

Substituting values

$P(-2$

From z table

$P(z\leq 2)=0.9772\\P(z\leq -2)=0.0228\\P(-2\leq z\leq 2)=P(z\leq 2)-P(z\leq -2)\\P(-2\leq z\leq 2)=0.9772-0.0228\\P(-2\leq z\leq 2)=0.9544\\$

So the probability that the sample mean will lie within 2 values of μ is 0.9544.
