Robert claims that his dog can do single-digit multiplication. He shows the dog 8 cards with simple multiplication problems that are either correct or incorrect. The dog correctly identifies the correctness of the card 5 times out of 8. If the dog were simply guessing, how many would the dog be expected to get correct? (1 point) Group of answer choices 5 8 13 4
Answer: Theorically it would be 4
Answer:
4
Step-by-step explanation:
Well since he has a 50% of getting it right, we use 50% of 8 which would be 4

A sphere with a radius of 21cm JUST fits in a cube-shaped box. Calculate the amount of empty space in the box rounded to the nearest tenth of a cubic centimetre.
How do you solve this?
Answer:
Since its a cube and a sphere just fits in side it we know that both the sphere and the cube are 21cm wide and since its a cube the dimensions of the cube is 21*21*21 giving you 9,261 cm³ then you find the volume of the V=4/3π10³≈4849.04826 now all you have to do is subtract your two totals to get 4411.95174
Step-by-step explanation:

Answer:
35,295.6 cm^3 to the nearest tenth.
Step-by-step explanation:
The diameter of the sphere = 2*21 = 42.
The volume of the box = 42^3 ( because the dimensions of the box = the diameter of the sphere).
The volume of the sphere = 4/3 π r^3
= 4/3 π 21^3
So the empty space = 42^3 - 4/3 π 21^3
= 35295.615 cm^3.

Emma took 20 1/4 cookies for her sleepover there was 50 1/2, Ava took 20 1/6 how many cookies did they both take
Answer:
40 5/12
Step-by-step explanation:
The cookies they both took can be determined by adding 10 1/4 and 20 1/6 together
[tex]20\frac{1}{4} + 20\frac{1}{6}[/tex]
[tex]40\frac{6 + 4}{24}[/tex]
[tex]40\frac{10}{24}[/tex]
the fraction is not in its simplest form, To transform the fraction to its simplest form, divide both the numerator and the denominator by 2
40 5/12
At a pet store, there are 30 aquariums.
Of the 30, 20 have fresh water with
15 fish each. The other 10 aquariums
have salt water with 6 fish each. Which
equation could be used to find f, the
total number of fish at the pet store?
Answer:
f = (20 × 15) + (10 × 6)
Explanation:
You are just find how many fish are salt water and how many freshwater and adding them together. The total number of aquariums is irrelevant in this case.

Sally designed a gold bracelet using 8 thin gold circles, arranged each circle has a radius of 2.5 what is the diameter and what is the length '5cm' of the chain
Answer:
Diameter of the circle = 5.0 unit
The length of the chain = 40 units
Step-by-step explanation:
Given
Number of thin gold circles used for making bracelet is equal to 8
Radius of the circle = 2.5 units
Diameter of the circle = 2 * Radius of the circle
Diameter of the circle = 2 * 2.5 = 5.0 unit
The length of the chain = 8 * diameter = 8 * 5 = 40 units

How do u work the problem m/-14 < -4 out
Answer:
m = 56
Step-by-step explanation:
The same way you would solve an equation.
m/-14 < -4
multiply both sides by -1
-1(- m/14) < -1 (-4)
since you are multiplying by a negative number, invert the inequality sign
m/14 > 4
multiply both sides by 14
m = 4 * 14
m = 56
Annabel is comparing the distances that two electric cars can travel after the battery is fully charged. Car A (miles) Car B (miles) Mean 145 200 Median 142 196 IQR 8 4 MAD 6 2 Part A Use the measures of center to make an inference about the data. Use the drop-down menus to complete your answer. Car A can travel further than Car B after the battery is fully charged. Part B Based on the data, which car performs most consistently? Explain. A. Car A because the measures of center are smaller for Car A than for Car B. B. Car B because the measures of center are smaller for Car B than for Car A. C. Car A because the measures of variability are smaller for Car A than for Car B. D. Car B because the measures of variability are smaller for Car B than for Car A.
Answer:
Car B can travel further than Car A after the battery is fully charged.
D. Car B because the measures of variability are smaller for Car B than for Car A.
Step-by-step explanation:
Car B can travel further than Car A after the battery is fully charged because Car A has lesser mean and median than Car B.
Median divides the data into two halves. A smaller median means that there is lesser mileage of Car A than Car B.
There are two measures.
Measure of center tells us how much near or far the data is spread from the center.
The mean , median and mode are the measures of center.
Car A has less mean , median telling us that it traveled less.
Measure of Variability tells us how data changes with a single value.
Smaller MAD means the data is denser at the mean. Car B has lesser MAD.
Smaller IQR tells us that data is closer to the middle of the data.
Car B has smaller IQR .
So car B traveled consistently as it has smaller IQR and MAD
D. Car B because the measures of variability are smaller for Car B than for Car A.
Answer:
Car B can travel further than Car A after the battery is fully charged.
D: Car B because the measure of variability is smaller for Car B than for Car A.

Answer:
MN = 4 units
m<MLN = 42 degrees
Step-by-step explanation:
For this problem, we need to know the definition of congruence. Two shapes are said to be congruent if the angles and sides have the exact same measurements.
We are given that these two triangles are congruent, so we know they are the same. XYZ ~= NML
Since we know this, we simply rotate the triangles to be the same to know the measurements.
We know that XY = MN = 4 units.
We know that m<YZX = m<MLN = 42 degrees.
So, these are the solutions.
Cheers.

A rectangle has a length of 25 feet and a width of 18 feet what is the area model of the rectangle
Answer:
450 sq.feet
Step-by-step explanation:
Given,
Length ( l ) = 25 feet
Width ( b ) = 18 feet
To find :
Area ( rectangle ) = ?
Formula : -
Area ( rectangle ) = l x b
Area ( rectangle )
= 25 x 18
= 450 sq.feet

Martin is considering the expressions 12(7x+48) and −(12x−3)+4(x+5). He wants to know if one expression is greater than the other for all values of x. Show or explain how you found your answer to Part A. Enter your work or your explanation in the box provided.Write a new expression that always has a greater value than both of these expressions. Enter your expression in the box provided.
Answer:
Part A
The first thing we must do for this case is to rewrite both expressions.
We have then:
1/2 (7x + 48) = (7/2) x + 24
- [1 / 2x - 3] + 4 (x + 5) = - (1/2) x + 3 + 4x + 20 = (7/2) x + 23
Answer:
We note that the first expression is greater than the second for all values of x.
Part B:
A new expression that is greater than both written expressions is:
(7/2) x + 25
For all values of x, this expression is always greater.
Answer:
(7/2) x + 25

How many credit hours a student have to take for the two tuition cost to be equal round the answer to the nearest 10th of an hour 250+200 H equals 300+180 250+200 H equals 300+180-180-180 H 250+20 = 300 H equals credit hours
Answer:
Total credit hours a student have = 2.5 hours.
Step-by-step explanation:
P.S - The exact question is -
Given - The tuition costs, C, for a local community college are modeled by C(h) = 250 + 200h, where h represents the number of credit hours taken. The local state university has tuition costs, S, modeled by the function S(h) = 300 + 180h.
To find - How many credit hours will a student have to take for the two tuition costs to be equal.
Proof -
If the two tuition cost are equal, then
C(h) = S(h)
⇒250 + 200h = 300 + 180h
⇒200h - 180h = 300 - 250
⇒20h = 50
⇒2h = 5
⇒h = [tex]\frac{5}{2}[/tex]
⇒h = 2.5
∴ we get
Total credit hours a student have = 2.5 hours.

Susan estimated she would spend $250 on school clothes at the start of the school year. She actually ended up spending only $230. What was her percent of error in her calculations?
Answer:
8.7%
Step-by-step explanation:
the formula for % error is = [ (approx. - exact ) / exact ] x 100
so, we know the approx value was 250 while the exact one is 230
thus; [ ( 250-230 ) / 230 ] x 100
= 8.7%
