A cereal box is 8 inches by 2 inches by 12 inches. Its surface area is square inches.

Part B

stira [4]

<h3>Given:</h3>

Radius of 50 point region= 3 in
Width of other regions= 4 in

The area of the target which earns 30 points on a throw.

<h3>Solution:</h3>

$\huge\boxed{Formula: a= \pi{r}^{2}}$

$4+3$

$=7$

Let's solve

We have to find the answer in terms of π so, we'll just have to multiply the radius by itself.

$a={7}^{2}$

$\large\boxed{a= 49 \pi\: {in}^{2}}$

Hence, the area of the target which earns 30 points on a throw is 49π square inches.

Answer= Option B

Solve the system by elimination. State whether the system has one solution, infinite solutions, or no solution.

lukranit [14]

I'm not sure I'm right, I'm not all that good at elimination but I think the answer is y = 13. So I guess the answer would be A. one solution

Based on the data in the two-way table, the probability of being older than 25 years and having a hemoglobin level above 11 is

marta [7]

Based on the data in the two-way table, the probability of being older than 25 years and having a hemoglobin level above 11 is
(154-69)/(429-139)
=85/290
=0.2931~0.29
Answer: A. 0.29

The probability of having a hemoglobin level above 11 is
P(H>11)
=154/429
=0.35897~0.36
Answer: C:0.36

Being older than 25 years and having a hemoglobin level above 11

Answer this please, thank you !

Answer:

m∠ADC=55°

Step-by-step explanation:

step 1

Find the value of x

we know that

m∠CDE+m∠EDF=180° ----> by supplementary angles (form a linear pair)

substitute the given values

$(2x+1)\°+(x-7)\°=180\°$

solve for x

$2x+x=180+6$

$3x=186$

$x=62$

step 2

Find the measure of angle ∠ADC

we know that

m∠ADC=m∠EDF ----> by vertical angles

m∠EDF=(x-7)°

substitute the value of x

m∠EDF=(62-7)°=55°

therefore

m∠ADC=55°

-PLEASE ANSWER- An experiment was repeated a number of times and the following measurements were obtained:

gladu [14]

Answer:

Step-by-step explanation:

From the given data, it can be observed that there are two number that are abnormal and extremely different from others, 322 and 19. Eliminating these two numbers would reduce the error that can be generated.

Then to obtain the best single result from the measurements, find the mean of the other numbers.

i.e 52.3, 52.5, 52.2, 52.6

Mean = $\frac{52.3 + 52.5 + 52.2 + 52.6}{4}$

= $\frac{209.6}{4}$

= 52.4

Thus the best single result that can be obtained is 52.4.
