To change from gram to kilograms you move the decimal 3 places to the left.
4458 grams is 4.458 kilograms

What are the distributive property 14k+35

malfutka [58]

I’m not too sure of what you are asking. But if you want an equivalent expression, it would be

7(2k+5)

Since 7 is the greatest common factor of both 14 and 35. 14/7=2. 35/7=5

Find the greatest common divisor of 100 and 254, using • prime factorization- • euclidean algorithm-

larisa [96]

Via prime factorization:

$100=10^2=2^2\cdot5^2$
$254=2\cdot127$

of which the only common factor is a single power of 2, so $\mathrm{gcd}(100,254)=2$ .

Via the Euclidean algorithm:

$254=2\cdot100+54$
$100=1\cdot54+46$
$54=1\cdot46+8$
$46=5\cdot8+6$
$8=1\cdot6+2$
$6=3\cdot2+0$

which means $\mathrm{gcd}(100,254)=2$ , as expected.

simple random sample from a population with a normal distribution of 99 body temperatures has x overbarequals98.20degrees Upper

Verizon [17]

Answer:

Step-by-step explanation:

Let x be the normal body temperature

X is N(99, sigma)

Sample mean x bar = 98.2 and s = 0.63

Margin of error = Z critical * 0.63 = 1.95 *0.63 = 1.2285

It is safe since 1.5 <1.96 critical value of z at 95%

What is the solution to this system of linear equations?

Readme [11.4K]

Answer:

(7,3)

Step-by-step explanation:

you can add the equations together to eliminate y and first solve for x

(x-3y = -2) + (x+3y=16) = (2x = 14)

x = 7

then plug x into one of the equations to solve for y

(7) - 3y = -2

9 = 3y

y = 3

the solution is (7,3)
