Hello!

a) 6 pounds

$9 is three times the cost we are given. Therefore, we multiply our original two pounds by three, giving us 6.

b) You would not be able to

There are 16 ounces in a pound. If each one weighs 5 ounces, it would be 5/16 of a pound. This would be 5/16 of $1.5, which is about 0.47. If we multiply this by 24 oranges, we get a cost 11.28, which is more than $9.

I hope this helps!

A / you can buy 6 pounds for 9 dollars.

B / No you cannot. If 1 orange is 5 ounces, 24 oranges all together is 7.5 pounds. Since its 2 pounds for 3 dollars, you could get 6 pounds out of the 7.5 and that would be 9 dollars. But you would have 1.5 pounds left.

Y = mx + b is the slope-intercept form of the equation of a line,
where m = slope, and b = y-intercept.

In problems 1 and 3, your equations are written in the y= mx + b form, so you can read the slope and y-intercept directly.

1.
m = -5/2
b = -5

3.
m = -1
b = 3

5.
For problem 5, you need to solve for y to put the equation
in y = mx + b form. Then you can read m and b just like we did
for problems 1 and 3.

4x + 16y = 8

16y = -4x + 8

y = -4/16 x - 8/16

y = -1/4 x - 1/2

m = -1/4

b = -1/2

Forty percent of households say they would feel secure if they had $50,000 in savings. you randomly select 8 households and ask

Kay [80]

Answer:

Let X be the event of feeling secure after saving $50,000,

Given,

The probability of feeling secure after saving $50,000, p = 40 % = 0.4,

So, the probability of not feeling secure after saving $50,000, q = 1 - p = 0.6,

Since, the binomial distribution formula,

$P(x=r)=^nC_r p^r q^{n-r}$

Where, $^nC_r=\frac{n!}{r!(n-r)!}$

If 8 households choose randomly,

That is, n = 8

(a) the probability of the number that say they would feel secure is exactly 5

$P(X=5)=^8C_5 (0.4)^5 (0.6)^{8-5}$

$=56(0.4)^5 (0.6)^3$

$=0.12386304$

(b) the probability of the number that say they would feel secure is more than five

$P(X>5) = P(X=6)+ P(X=7) + P(X=8)$

$=^8C_6 (0.4)^6 (0.6)^{8-6}+^8C_7 (0.4)^7 (0.6)^{8-7}+^8C_8 (0.4)^8 (0.6)^{8-8}$

$=28(0.4)^6 (0.6)^2 +8(0.4)^7(0.6)+(0.4)^8$

$=0.04980736$

(c) the probability of the number that say they would feel secure is at most five

$P(X\leq 5) = P(X=0) + P(X=1) + P(X=2) + P(X=3) + P(X=4) + P(X=5)$

$=^8C_0 (0.4)^0(0.6)^{8-0}+^8C_1(0.4)^1(0.6)^{8-1}+^8C_2 (0.4)^2 (0.6)^{8-2}+8C_3 (0.4)^3 (0.6)^{8-3}+8C_4 (0.4)^4 (0.6)^{8-4}+8C_5(0.4)^5 (0.6)^{8-5}$

$=0.6^8+8(0.4)(0.6)^7+28(0.4)^2(0.6)^6+56(0.4)^3(0.6)^5+70(0.4)^4(0.6)^4+56(0.4)^5(0.6)^3$

$=0.95019264$

there are 2.54 centimeters in 1 inch. there are 100 centimeters in 1 meter.questionto the nearest meter, how many meters are in

Gre4nikov [31]

There are 7 meters in 279 inches.

There are 2.54 centimeters in 1 inch.
There are 100 centimeters in 1 meter.
The number of inches is given to be 279.
Unit conversion is a multi-step procedure that includes multiplying or dividing by a numerical factor, determining the appropriate number of significant digits, and rounding.
First of all, we need to convert inches to centimeters.
1 inch equals 2.54 centimeters.
279 inches equals 2.54*279 centimeters.
279 inches equals 708.66 centimeters.
Now, we need to convert these centimeters into meters.
Meters in 100 centimeters = 1
Meters in 1 centimeters = 1/100
Meters in 708.66 centimeters = (1/100)*708.66
Meters in 708.66 centimeters = 7.0866
Thus, there are approximately 7 meters in 279 inches.
