Several different cheeses are for sale. The cheese comes in wedges

Tom [10]

Answer:

area = 39.25 cm²

Step-by-step explanation:

The top and bottom area of a cheese wedge is shaped like a sector of a circle so finding the area of the top surface of this wedge is same as applying the area of a sector.

Top surface area(sector) = ∅/360 × πr²

where

∅ = central angle

r = radius

Top surface area(sector) = ∅/360 × πr²

area = 45/360 × π × 10²

area = 1/8 × 100π

area = 100π/8

area = 100 × 3.14/8

area = 314 /8

area = 39.25 cm²

Researchers are planning a study to estimate the impact on crop yield when no-till is used in combination with residue retention

Greeley [361]

Answer: n= 14

Step-by-step explanation:

The formula to find the sample size :_

$n= p(1-p)(\dfrac{z^*}{E})^2$

, where p= Prior estimate of population proportion.

z* = Critical value.

E= Margin of error.

Given : Prior estimate of population proportion : p= 0.025

We know that , the critical value for 90% confidence interval :

$z^*=1.645$

E= 7.0%=0.070

Then , the required minimum sample size :

$n= (0.025)(1-0.025)(\dfrac{1.645}{0.07})^2\\\\=(0.025)(0.975)(23.5)^2\\\\13.46109375\approx14$

i.e. n= 14

Hence, the sample size needed : n= 14

Given the arithmetic sequence 4,7,10,13

Anastaziya [24]

Answer:

$b. \: a_n =4+ 3(n-1)$

Step-by-step explanation:

Given Arithmetic sequence is: 4, 7, 10, 13

Here,

First term (a) = 4

Common Difference (d) = 7 - 4 = 3

nth term of an Arithmetic sequence is given as:

$a_n = a + (n-1)d$

Substituting the values of a and d in the above sequence, we find:

$a_n = 4 + (n-1)\times 3\\\therefore a_n =4+ 3(n-1)\\\huge \red {\boxed {\therefore a_n =4+ 3(n-1)}} \\$
