Answer: 10mm

Step-by-step explanation: First you have to set up an equation using the formula: (a squared)+(b squared)=(c squared), (24 squared) + (x squared)=(26 squared

Then, solve for x: (26 squared)- (24 squared)= 676-576=100

Lastly, find the square root of 100, which is 10!

Hope this helps and I would appreciate it if you marked me as brainliest, but u don't have to!

a2+b2=c2

a=x

b=24

c=26

a2+24 squared=26 squared

a2+576=676

-576 -576

a2=100

Then, square root both sides.

It should be a/x=10

If you can walk 5.3 miles in 2.5 hours, how many minutes does it take to walk 3.18 miles? Round to 1 decimal.
Oksana_A [137]

Answer:

90min

Step-by-step explanation:

we can solve the first part by means of the rule of three:

5.3miles ----2.5 hour

3.18miles----x

then

x=\frac{3.18*2.5}{5.3} \\x=\frac{7.95}{5.3} \\x=1.5 hours

Now we must convert hours to minutes:

1.5 hours = 1.5hours (1)

1.5 hours =1.5 hours \frac{60min}{1 hours}

1.5 hours =(1.5)(60) min

1,.5 hours =90min

-4/3x+1/6 <7/9 please answer asap
xz_007 [3.2K]

Answer:x=−24/11

Step-by-step explanation:

Simplifies to:

x−86x=79

Let's solve your equation step-by-step.

x−86x=79

Step 1: Cross-multiply.

x−86x=79

(x−8)*(9)=7*6x

9x−72=42x

Step 2: Subtract 42x from both sides.

9x−72−42x=42x−42x

−33x−72=0

Step 3: Add 72 to both sides.

−33x−72+72=0+72

−33x=72

Step 4: Divide both sides by -33.

−33x−33=72−33

x=−2411

Lloyd's Cereal company packages cereal in 1 pound boxes (16 ounces). A sample of 36 boxes is selected at random from the product
Reptile [31]

Answer: 0.0304

Step-by-step explanation:

A z-test is a statistical test that is used to determine if two population means are different when the variances are known and the sample size is large. The test statistic is assumed to have a normal distribution, and nuisance parameters such as standard deviation should be known in order for an accurate z-test to be performed.

A z-statistic, also known as z-score, is a number representing how many standard deviations above or below the mean population a score derived from a z-test is.

Therefore,

sample size,n = 36

mean,u = 16 ounce

standard deviation,s = 0.2 pounds = 3.2 ounce

x = 15 ounce

z = (x-u) / (s/sqrt(n)) = -1.875

In conclusion, the probability that the amount dispensed by box will be increased is:

P(X<15) = P(Z<-1.875)

= 1 - P(Z<1.875)

= 1 - 0.9696

0.0304

The Answer is 0.0304.
