What’s greater 7.8 mL or 0.78 L
Answer:
7.8 mL
Step-by-step explanation:
Answer:
.78 L
Step-by-step explanation:
Well, simple conversions
a milliliter is .0001 of a liter and 1 liter is 1000 mL, so we can safely say that .78 L is 780 mL, dwarfing the given 7.8 mL

FIRST TO ANSWER GETS MARKED BRAINLEST! please look at picture. The probability that a student guesses the correct answer to a four-choice multiple choice question is P(correct) = 0.25. How many correct answers should a student expect to guess on a test with 56 four-choice multiple choice questions?
A student should expect to guess_______correct answers.
Answer:
14 answers
Step-by-step explanation:
since there is 1/4 of a chance to get a question right by guessing you need to see what 1/4 of 56 is, which is 14
A researcher is 95% confident that the interval from 5.2 hours to 7.8 hours captures u = the true mean amount of time
it takes to fully charge a battery pack.
Is it plausible that the true mean number of hours to charge all battery packs of this type may be 5?
O No, this is not a plausible value for the population mean, because 5 is within the 95% confidence interval.
No, this is not a plausible value for the population mean, because 5 is not within the 95% confidence interval.
O Yes, this is a plausible value for the population mean, because 5 is within the 95% confidence interval.
Yes, this is a plausible value for the population mean, because the lower bound of the confidence interval, 5.2, is
greater than 5.
No, this is not a plausible value for the population mean, because 5 is not within the 95% confidence interval.
====================================================
Explanation:
The greek letter mu is the population mean. It has the symbol [tex]\mu[/tex] which looks like the letter 'u' but with a tail at the front or left side.
The question is asking if mu = 5 is plausible if the researcher found the 95% confidence interval to be 5.2 < mu < 7.8
We see that 5 is not in that interval. It's a bit to the left of 5.2
Since mu = 5 is not in the interval, it's not a plausible value for the population mean.
Have we ruled it out with 100% confidence? No. Such a thing is not possible. There's always room for (slight) error. The researcher would need to do a census to be fully confident; however, such practices are very time consuming and expensive. This is the main reason why statistics is important to try to estimate the population with a sample.
Brandon is half of Ella's age. Ella is three times Tristans age. In fifteen years, their combined age will be 89. How old is Brandon?
Answer:
Step-by-step explanation:
Let Brandon's age be [tex]x[/tex]
Therefore Ella=[tex]2x[/tex]
Tristan= [tex]\frac{2x}{3}[/tex]
Fifteen years time add 15 to each age
Brandon: [tex]x+15[/tex]
Ella: [tex]2x+15[/tex]
Tristan:[tex]\frac{2x}{3} +15[/tex]
All their ages together=89
So: [tex]x+15[/tex] + [tex]2x+15[/tex] + [tex]\frac{2x}{3} +15[/tex][tex]=89[/tex]
[tex]3\frac{2}{3} x=44[/tex]

For the function g(x)=5x2+4x−5, find g(−5)
Answer:
100
Step-by-step explanation:
g(x)=5x^2+4x−5
Let x = -5
g(x)=5 ( -5)^2+4(-5)−5
= 5*25 - 20 -5
=125 - 25
= 100
What is -86 + x = - 4x + 29
Answer:
x = 23
Step-by-step explanation:
Add 4x to the left and add 86 to the right.
5x = 115
Now, divide 5 on both sides to get x.
x = 23.
The result is 23.
Answer:
x= – 115/3

the total of 3/4 and a number is no more than 2
3/4=a fraction
Answer:
Step-by-step explanation:
Let the number be x
[tex]\dfrac{3}{4}+x \leq 2\dfrac{3}{4}\\\\\\\dfrac{3}{4}+ x \leq \dfrac{11}{4}[/tex]
Subtract 3/4 from both sides
[tex]\dfrac{3}{4}-\dfrac{3}{4}+x\leq \dfrac{11}{4}-\dfrac{3}{4}\\\\\\x \leq \dfrac{11-3}{4}\\\\\\x \leq \dfrac{8}{4}\\\\\\x \leq 2[/tex]

∠A and ∠B are complementary. The measure of ∠A is 21°.
What is the measure of ∠B?
Enter your answer in the box.
point theif = ban
Answer:
69°Step-by-step explanation:
Complementary angles sum to 90°.
We have the measure of one angle, find the missing one as below.
m∠A + m∠B = 90°21° + m∠B = 90°m∠B = 90° - 21°m∠B = 69°Complementary angles have sum 90°
[tex]\\ \sf\longmapsto x+21=90[/tex]
[tex]\\ \sf\longmapsto x=90-21[/tex]
[tex]\\ \sf\longmapsto x=69[/tex]

6 6 small bricks have the same mass as 5 large bricks. The mass of one small brick is 2.5 kg. What is the mass of one large brick?
Since 6 small bricks have the same mass as 5 large bricks and the mass of one small brick is 2.5 kg, the mass of one of the large bricks is 3 kg
What is mass?Mass is the quantity of matter in a physical body.
6 small bricks have the same mass as 5 large bricks.
let
the total mass of the small or large bricks = x
Therefore,
6 × 2.5 = x
x = 15 kg
Therefore, the mass of each large bricks can be calculated as follows:
let the mass of each large bricks = y
15 = 5y
divide both sides by 6
y = 15 / 5
y = 3 kg
Therefore, the mass of one of the large bricks is 3 kg
