Answer:

m < 36

yes, Jamie is correct.

Step-by-step explanation:

I've bolded the statements that you can put down to show your work

the maximum that Jamie is willing to practice for the week is 300 minutes, so you can start by creating an inequality for that.

total minutes throughout the week < 300

next, you know that a week is monday through friday + the weekend, and the amount of minutes Jamie will practice for the weekend is already given.

so, you can rewrite the earlier inequality like so

Monday through Friday practice + 120 < 300

since Jamie plans to practice the same amount of time (m) for each day, and there are 5 days between monday and friday, you can substitute values in the equation

5m + 120 < 300

simplify

5m < 300 - 120

5m < 180

m < 36

since half an hour is 30 minutes, the answer is yes, Jamie's claim is correct.

what is the equation to seven less than the product of twice a number is greater than 5 more than the same number

postnew [5]

seven less than (-7) than the product of twice a number (2x) is greater than (>) five more than (+5) the same number (x)

2x-7>x+5
treat the > sign as an equals for now
2x-7=x+5
subtract x from both sides
x-7=5
add 7 to both sides
x=12
put the > sign back in
x>12

balandron [24]

Answer:

The first step is to determine the average

$x= \frac{0,6+0,7+ 0,7+0,3+0,4+ 0,5+ 0,4 +0,2}{8}\\\ x= 0,475$

The exercise says it’s a normal distribution: (n=8)

$s^{2}= \frac{1}{n-1} ((0,6.x)^2+2(0,7-x)^2+(0.3-x)^2+2(0.4-x)^2+(0.5-x)^2+(0.2-x)^2)\\\ \frac{1}{7}*0,235 = 0,0336 \\\\ s= 0183$

According to the exercise, the mean is equal to 0,5 then the value of t of the distribution can be obtained

$t= \frac{x-u}{\frac{s}{\sqrt{n} }}\\\ t= \frac{0,475 - 0,5}{0,183}\\\ t= -0,3860$

The variable t has 7 grade to liberty, we calculate the p-value as:

$2* P(t < - 0,3860)= \\\ 2* 0,3554 = 0,7108$

This value is very high, therefore the hypothesis is not rejected

Can you help me find the value of x and y. I am very confused.

Hello,
Let's assume top left corner: A
top right corner : B
Bottom right corner: C
Bottom left corner :D

M= middle of [CD]

ABM is a triangle rectangular isocel:

(3√2)²+(3√2)²=y²
==>y²=2*9*2
==>y²=36
==>y=6

The triangle BCM is rectangular with MB=3√2, MC=y/2=3
x²+3²=(3√2)²
==>x²=9*2-9
==>x²=9
==>x=3

Solve for x. Show each step of the solution. 5.5(8-x)+44=104-3.5(3x+24)

earnstyle [38]

5.5 ( 8 - x ) + 44 = 104 - 3.5 ( 3x + 24 )

Distribute 5.5 through the parenthesis.

44 - 5.5x + 44 = 104 - 10.5x - 84

Add the numbers.

88 - 5.5x = 20 - 10.5x

Move variable to the left side and change its sign.

88 - 5.5x + 10.5x = 20
-5.5x + 10.5x = 20 -88

Collect like terms.

5x = 20 - 88

Calculate the sum or difference.

5x = - 68

Divide both sides by 5.

x = - 68 / 5
